FIREWOOD HOT WATER CENTRAL HEATING BOILERS MODEL: STADLER TR STADLER TR firewood hot water central heating boilers provide comfortable and energy saving heating. Such heating is enabled with integration of the new innovative technology in the field of control and modern production technology. s are constructed for burning all types of wood and reach efficiencies of over 91%. Constant growth of fossil fuel prices and the increased care for the environment make this boiler even more important. By using different types of wood, even of different humidity, these boilers allow you to reach perfect combustion conditions. Emitted flue gases are harmless to the natural balance. You should load the boiler with ½ m long firewood as close together as possible, thus reaching uniform fuel structure and stable combustion conditions. Single load should be enough for several hours of operation. Fireplace volume equals to 150 l and can be loaded with up to 50kg of hardwood logs. Connection to the power supply is very simple, as the boiler includes already prepared wiring with plug equipped cables. By purchasing our boiler, you meet all of the requirements to obtain your government's subsidy. Construction of the boiler incorporated the modern degassing combustion technology. The flame is vertically directed through the burner nozzle with the help of the controlled injection of the primary and secondary air. When the flame enters the combustion chamber, it swirls and in touch with the red-hot combustion chamber causes the remaining not-combusted wood gases to burn at temperatures of approx. 1000 C. The control regulates the operation of the primary and secondary air step motors, thus supplying the combustion process with regulated quantities of air which enable the best combustion. The large panel shielded loading place protects the boiler from accumulation of tar and ensures long service life of the boiler. s can be loaded with firewood of up to 56 cm in length. The burner nozzle is made of chrome alloy which also significantly prolongs the service life of the boiler. 2 The boiler is included in the German BafA-List and therefore entitled to incentives. The fireproof clay combustion chamber is upgraded with the bottom made of high-temperature resistant concrete which guarantees complete combustion of wood gases. s are equipped with the Lambda probe, temperature sensor and continuously controlled electric motor of the fan.

FIREWOOD HOT WATER CENTRAL HEATING BOILERS MODEL: STADLER GT STADLER GT boilers belong to a new generation of firewood hot water heating boilers. With their wood gasification technology they enable modern and energy saving heating. They are constructed to burn all types of firewood of up to 54 cm or 33cm in length. Their combustion efficiency reaches over 90%. themselfs are designed and produced in Slovenia. By naming the product range STADLER we wished to show that the production is still active and adapts to new combustion conditions and techniques. These boilers provide stable combustion processes enabled by the inovative construction and lambda probe. They achieve excellent combustion parameters which are characteristic for wood gasification boilers. Quality production, controlled combustion process and high efficiency of these boilers beat the competition of the lower priced boilers by far. By using different types of wood, it is possible to achieve good combustion conditions in the boiler. Firewood burns in the lower part, whilst the supplied primary air leads the flame and wood gases downwards into the combustion chamber. When flue gases come through the burner nozzle, they are blown with controlled supply of secondary air. Flue gases mixed with the flame and fresh air swirl in the combustion chamber, and in touch with the red-hot fireproof clay, burn with extreme temperatures. The control regulates the combustion process via lambda probe and the temperature sensor in the chimney and sensors installed in the boiler and the accumulator. It also regulates the continuous control of the fan and the primary and secondary combustion air supply motor flap. Controlled supply of the combustion air enables low values of emmissions in flue gases which are significantly lower than the law regulated ones. s are equipped with an insulated hot combustion chamber made of fireproof clay which quickly reaches high temperatures and enables good combustion of wood gases. The efficiency boilers reache over 90% which points out the top-class echievement. The hot combustion chamber enables the boiler to reach the optimal combustion process in only minutes. These boilers must be installed into systems equipped with hot water accumulators. We recommend the use of the heating system control because this is the only way to preserve different water layers in the hot water accumulator. Our boilers are in compliance with all currently valid provisions on safety and construction design (e.g. DIN 4751 B1.1, DIN 4702, etc.). They are tested for pressure and water tightness, factory equipped with a thermal protection device and can be installed in closed heating systems. The permissible operating pressure of boilers equals to 3 bars. We recommend the use of firewood with humidity between 15 and 25% which is achieved by drying it outdoors for 2 years. You should load the boiler with firewood as close together as possible, thus reaching uniform fuel structure and stable combustion conditions. Single load should be enough for several hours of operation. The volume of the fireplace is 105 dm3 and can be loaded with approx. 30 kg of firewood. You should load the container with firewood to the top of the doors, while taking care not to load them too close to each other as this could cause jamming.

WOOD PELLET HOT WATER CENTRAL HEATING BOILERS MODEL: STADLER PELET STAR Stadler PELET STAR hot water central heating boilers belong to a new generation of wood pellet boilers. They were designed by our company in cooperation with the Swedish company Ariterm. The BeQuem burner enabled the development of a completely automatic wood pellet boiler which guarantees reliable and safe operation with minimum cleaning and maintenance interventions. s are produced with the modern sheet metal treatment technique. Construction concepts provided the boiler with a touch of modern design, while respecting the ergonomic demands for the operation of the boiler. Construction of the boiler is produced in accordance with regulations DIN 4751 B1.1, DIN 4702, EN 303-5. s are equipped with the CE 0036 marking and can also be installed in smaller rooms to provide comfortable and energy saving heating. The side of the boiler is equipped with the weekly wood pellet silo, whilst the large ash chamber allows longer intervals between cleaning. Construction of boilers allows easy access to all internal surfaces and hence easier cleaning and maintenance. We recommend you to install your central heating system with a hot water accumulator which allows optimum boiler operation with low energy consumption (low-energy constructions and transition periods). In case of bigger consumption, the hot water accumulator amortizes the current lower burner operation capacity. Special construction of the BeQuem wood pellet burner allows reliable operation and high level of safety. Wood pellet feeding is arranged with a double stoker system where the lower stoker feeds wood pellets into the lower part of the combustion chamber. With such wood pellet feeding the ash is pushed further and the combustion chamber automatically cleaned. Such feeding technique makes the burner appropriate even with wood pellets of weaker quality which can now often be found on the market. Fire safety is ensured with temperature sensors and the cell block. Ignition and control of the flame are controlled with a special sensor.

WOOD PELLET HOT WATER CENTRAL HEATING BOILERS MODEL: STADLER EKO PELET Stadler EKO PELET hot water central heating boilers were designed with combination of firewood boilers and Swedish made burners. In this way boilers with the BeQuem wood pellet burners became automated units for heating of living quarters. Unlike the use of fossil fuels, the use of local energy resources, such as wood pellets, is harmless to the environment and decreases heating costs. These wood pellet boilers are equipped with a control which allows completely automated operation of the boiler without constant regulation. They regulate the supply of pellets from the container and the combustion process. s are also equipped with a pellet ignition device and flame control. The burner activates automatically as soon as the sensor in the boiler detects fall of water temperature bellow the preset value, and deactivates as soon as this temperature is reached. The volume of the factory offered wood pellet container equals to 0.6 m3 which is enough for approx. 10 days of operation. Alternatively you can order a larger container with volume of 0,93 m3. Our company also offers elements for the construction of even larger wood pellet containers which can be assembled in your boiler room or the room next to it. These boilers can easily be rearranged into firewood heating boilers by unscrewing the flange screws, removing the burner and turning it into the position which does not interfere with the operation of the boiler. Then, you have to install the cover over the burner on the external side of the boiler. Fix the cover firmly and prevent the flue gases from escaping. Cleaning of the boiler is also very simple. Open the lower door and remove the ash collected in the drawer. From time to time it is also necessary to check if the combustion chamber is clean. In case you notice any slag residue, remove it adequately. We do not recommend you to disassemble the burner during cleaning, however if this is necessary please call our authorised repair service centre. After each rearrangement of the boiler for burning firewood, clean the fireplace of the boiler and the space under the grate. The construction of the burner is equipped with a display showing mode of operation and temperature. Under the display, there are some arrow keys which enable you to scroll along the simple menu. With the use of these keys you can set the operation of the burner or simply control its operation. Calculation of the required boiler power m 2 cm 0,30 Apartment x Living quarters x Heat loss size height coefficient Poorly insulated buildings, shady and high altitude positions require the use of a heat loss coefficient of 0.40. In case of simpler heating systems we recommend you to install a special pump. This special pump with a three-way valve ensures that the boiler first reaches the temperature of 60 C and then only emits the excess energy into the system. During the cool down phase, the pump and the three-way valve ensure that the water temperature in the boiler does not fall below 55 C, thus preventing the formation of condensate. If the system includes a hot water accumulator, the three-way mixing valve allows the accumulator to be filled. With the use of the water accumulator, better operation can be achieved, especially during transition periods when temperatures are not too low. model Wood pellet boiler capacity kw Firewood boiler capacity kw / 860 = Required boiler power Electric connection 240 V 50 Hz Power consumption 240 V 50 Hz Efficiency EKO PELET 20 10-20 30 450 W 60 W 91,5 % EKO PELET 40 25-40 40 600 W 90 W 90,7 % WVterm d.o.o., Valvasorjeva 73, 2000 Maribor, Tel.: +386 2 429 28 10, Fax: +386 2 420 21 67, wvterm@wvterm.si 9
WOOD PELLET AND FIREWOOD HOT WATER CENTRAL HEATING BOILERS MODEL: STADLER EKO PELET Kompakt EKO pelet Kompakt wood pellet hot water heating boilers are equipped with wood pellet containers located above the boiler where the domestic water heater is generally installed. These boilers are appropriate for installation in smaller spaces where there is desire for comfortable and energy saving heating. s are produced left or right oriented. They can easily be rearranged into firewood heating boilers by unscrewing the flange screws connecting the burner and the boiler, removing the burner and turning it into the position which does not interfere with the operation of the boiler and its safe loading. Then, you have to install the cover over the burner on the external side of the boiler. Fix the cover firmly and prevent the flue gases from escaping. Fasten the line of the draft regulator to the primary air flap of the lower door. Remove the safety barrier and the rectifier from the boiler. After you finish the above procedure, the boiler is rearranged to use firewood. CHARACTERISTICS OF FIREWOOD BOILERS: Stadler EKO hot water central heating boilers are constructed to burn 33 cm long firewood (logs are to be loaded transversely) and 56 cm long firewood (logs are to be loaded longitudinally to the boiler). They are intended for operation in the 90/70 C mode. The new way of flue gas conduction improves combustion processes during the burning of firewood. Loading doors enable loading of large logs. Constructions of boilers are produced in accordance with regulations DIN 4751 B1.1, DIN 4702 and EN 303-5. s are also equipped with the CE 0036 marking. Chimney must be constructed in accordance with solid fuel boiler chimney manufacturer's tables and must ensure drafts as described in the table of the brochure related to individual boiler models. s are equipped with large fireplaces, therefore we recommend you to burn your wood pellets or firewood in a downwards direction, thus prolonging the combustion time of a single load. During the burning phase, the draft regulator must constantly be set above 70 C, thus preventing overcooling of the return water and formation of condensate in the fireplace. We also recommend the installation of one of the insufficient water return prevention systems. Easy access to all internal surfaces enables easy cleaning and maintenance.

HOT WATER CENTRAL HEATING ACCUMULATORS MODEL: AT Hot water accumulators represent intermediate central heating elements and are used in modern heating systems. They are used for accumulation of the excess thermal energy produced by the boiler and for evenly regulated supply of energy to different consumers. Hot water accumulators are indispensable in systems with installed firewood, wood pellet, or wood chip heating boilers. Firewood heating boilers do not allow the complete control of power without significant interruption of the combustion process. Firewood combustion cycle brings excess thermal energy which consumers cannot use at that moment therefore it is conducted to the hot water accumulator. After the fuel has burnt and the heating elements cooled down, the automatic control takes care for transfer of hot water from the accumulator to heating elements. Our production programme includes hot water accumulators of various sizes: 500, 750, 1000, 1250, 1500, 1800, 2000, and 3000l. Accumulators are equipped with fittings for connection of heating circles, sensors and thermometers.

DUAL FIREPLACE FIREWOOD AND FUEL OIL CENTRAL HEATING BOILERS MODEL: STADLER TOBI Stadler TOBI central heating boilers are constructed as extremely energy saving boilers due to the installation of fuel oil and firewood boilers in a single construction. Both boilers use a single water reservoir, but completely separated fireplaces. Such design enables automatic rearrangement from burning of one type of fuel to another which cannot be achieved with combined boilers. s are basically intended for burning firewood in the 90/70 C operating mode. The fuel oil part of the boiler activates automatically after all of the fuel from the firewood fireplace has been used and the temperature dropped under the preset value. The fuel oil part of the boiler does not activate if the firewood fireplace is full and the preset temperature is reached. In case you deactivate the automatic system, these boilers only operate by burning firewood. A more modern construction concept classifies these boilers among the new generation of eco-friendly products as they operate in a similar way as hybrid cars. The firewood fireplace is equipped with modern burning in the lower side part of the boiler which enables controlled long burning process lasting even over 3 ½ h. The fireplace allows you to burn 33 cm long firewood. s are equipped with a return water preheating system and a cast iron grate which improves firewood combustion processes. Loading doors allow loading of large pieces of firewood. The special fireplace constructed for burning fuel oil is equipped with a hot combustion chamber and a turbulator in the third draft. Its design enables top-class efficiency of over 93%. Combusted flue gas emissions reach even more favourable parameters than required by law. The fuel oil part of the boiler is equipped with the SELTRON control. These boilers cannot be upgrades with domestic water heaters. Domestic water heaters can be installed as separated units which are then connected to the boiler. Ba purchasing the domestic water heater additionally, it is possible to control the temperature in the domestic water heater with the help of a pump. panelling is enamelled in the RAL 3000 or RAL 2004 colour combination. Our boilers are in compliance with all regulations regarding safety at work. Construction of the boiler is produced in accordance with regulations DIN 4751 B1.1, DIN 4702, EN 303-5, and is equipped with the CE 0036 marking. s are also equipped with a thermal protection device. The central heating system must compulsory include one of the system for lifting the return water as this is the only way to use the boiler with lower powers. If the boiler is not connected with the system for lifting return water the boiler condensates and causes poor combustion. This special pump with a three-way valve ensures that the boiler first reaches the temperature of 60 C, and emits only the excess energy into the system. At the same time it prevents the return water with temperatures lower than 55 C to enter the boiler, thus preventing the condensation. If the system includes a hot water accumulator, the three-way mixing valve enables the accumulator to be filled. With the use of the hot water accumulator, better operation of the burning device can be achieved, especially during the transition periods when temperatures are not too low, but still demand heating. model TOBI Power (fuel oil) kw Power (wood) kw Fireplace size dm 3 water quantity l Required draft Pa Weight kg Chimney Connection (fuel oil) Ø Chimney Connection (wood) Ø width mm height mm Required door width to enter the boiler with panelling into the room Required door width to enter the boiler without panelling into the room Efficiency (fuel oil) 20 15-20 20 86 105 15 230 130 160 990 1200 850 770 93,2 81,2 25 20-25 25 86 100 20 240 130 160 990 1200 850 770 93,4 81,5 % Efficiency (wood) % 16 WVterm d.o.o., Valvasorjeva 73, 2000 Maribor, tel.: +386 2 429 28 10, Fax: +386 2 420 21 67, wvterm@wvterm.si

FIREWOOD HOT WATER HEATING BOILERS MODEL: HDG Euro HDG Euro boilers are distinguished by very long loading intervals and efficiency of over 90%. They are effective, energy saving and comfortable for the user. Flue gas emission values are lower than all of the prescribed values. Contraction and production of the boiler are in accordance with all safety regulations. These boilers were granted the German innovation award and are equipped with the TÜV quality marking. Large fuel loading space significantly increases fuel reloading intervals. Cleaning of the boiler is easy as its doors are positioned in a way which enables easy access. s are delivered with installed panelling and are connected immediately. Connection with the power supply is very simple, as boilers include already prepared wiring with plug equipped cables. Combustion takes place in the lower side part of the boiler on the grate which allows wide selection of fuels. Along with the special combustion chamber, the robust and innovatively constructed burner nozzle provides swirling mixing of flue gases which ensures optimal combustion. After the combustion has finished, the flaps shut down and the fan deactivates. This prevents the boiler from cooling, whilst the next ignition is facilitated by the remaining charcoal. Grates are massive and equipped with a practical cleaning opening. The loading shaft is made of 10 mm thick quality steel sheet. Pneumatic cylinders facilitate opening of shaft doors. The system bolt of the loading shaft cover enables safe loading. The spacious conical loading shaft can be filled with firewood or bulk material. If you select the right size of the device, you will be able to get the necessary heating energy with only one loading of the boiler daily. Planning of the central heating system must include a hot water accumulator as such reservoir combined with the boiler control guarantees environment friendly combustion. The hot water accumulator significantly increases comfort of burning as it takes over the excess energy and transfers it back if necessary. The correct selection of the hot water accumulator enables very long loading intervals. During the summer, burning of a single load can be sufficient for several days of domestic water use. Volume of the accumulator depends on customer s demands regarding comfort, boiler power, volume of the loading shaft and the consumption of hot water for room heating. Combination of the firewood boiler equipped with the hot water accumulator and the solar energy device meets the demands of the modern heating system. Lambda control enables very low emission values, high efficiency and low fuel consumption. The adjustable primary and secundary air motors provide accurate amounts of combustion air to specific combustion areas. Primary air takes care for uniform combustion power, whilst the secundary air takes care for the lowest emission values and high efficiency throughout the combustion process.

In case you have fine fuel at your disposal, you can also additionally order the upper boiler loading doors. Turbotec boilers are distinguished by very long loading intervals and efficiency of over 90%. They are effective, energy saving and comfortable for the user. Flue gas emission values are lower than all prescribed values. Construction and production of the boiler are in accordance with all safety regulations. They are ideal for use in the craft industry, agriculture and forestry, and are equipped with the TÜV quality label granted by a German institution. Cleaning of the boiler is easy as its doors are positioned in a way which enables easy access. s are delivered with installed panelling and are connected immediately. Connection to the power supply is very simple, as boilers include already prepared wiring with plug equipped cables. The robust and innovative constructed nozzle provides good combustion. The interior of the combustion chamber is shielded with fireproof concrete. Swirling of flue gases in the combustion chamber provides optimal combustion. After the combustion has finished, the flaps shut down and the fan deactivates. This prevents the boiler from cooling, whilst the next ignition is facilitated by the remaining charcoal. s are made of quality steel sheet. Primary and secondary air servomotors deliver the necessary air directly in the combustion zone. Primary air takes care for constant performance of the boiler, whilst the secondary air takes care for the lowest flue gas emission values. If you select the right size of the device, you will be able to obtain the necessary heating energy with only one loading of the boiler daily. Planning of the central heating system must include the hot water accumulator as such accumulators combined with the boiler control guarantee environment friendly combustion. Installation of the hot water accumulator significantly increases comfort of burning as it takes over the excess energy and transfers it back if necessary. The correct selection of the hot water accumulator enables very long loading intervals. During the summer, burning of a single load can be sufficient for several days of domestic water use. Volume of accumulators depends on customer's demands regarding comfort, boiler power, volume of the loading shaft and the consumption of hot water for room heating. HDG Turbotec boilers are equipped with HDG lambda control 1 which ensures very low emission values, high efficiency and low fuel consumption. Adjustable primary and secondary air motors deliver accurate amounts of combustion air to specific combustion areas. Primary air takes care for uniform combustion power, whilst the secundary air takes care for the lowest emission values and high efficiency throughout the combustion process. 1394 1218 540 280 180 270 576 1939 1785 1606 60 Power Loading Loading Loading Chimney Required Operating Max. flow Model space volume space depth space width water quantity connection Ø draft pressure temperature weight kw l mm mm l mm Pa Bar C kg HDG Turbotec 50 L 50 340 1100 540 370 180 15 3 95 940 HDG Turbotec 60 L 60 340 1100 540 370 180 15 3 95 940 20 WVterm d.o.o., Valvasorjeva 73, 2000 Maribor, tel.: +386 2 429 28 10, Fax: +386 2 420 21 67, wvterm@wvterm.si
HDG WOOD CHIP AND WOOD PELLET HEATING SYSTEMS MODEL: HDG Compact These boilers are appropriate for burning wood pellets and wood chips with humidity of up to 45%. s can also burn Class 6 and 7 fuels. The compact and favourable priced versions are appropriate for use in households, agriculture, craft industry and public institutions, basically everywhere where a reliable and economic operation is required. Constant power is provided by the automatic technology of angled or movable grates. s are equipped with automatic ignition via the hot air fan. Two large external ash collectors make operation and maintenance easy. s are distinguished by low emission values and optimum efficiency of over 90%. The reliable fuel loading technology and the fire extinguishing device provide absolutely safe operation. Cell block is especially accurately manufactured and takes care for proper loading. Vertical surfaces of the heat exchanger provide better heat transfer. In emergency situations boilers can also burn firewood. HDG Compact electronic control device of the boiler takes care for good combustion technology and is a product of our development programme. It can also be upgraded for control of different heating systems. All actual conditions of the operating device are shown on the display. Fuel loading takes place directly on combustion grates. Fuel supply and primary and secondary air can be adjusted independently. Even in case of bigger shares of non-combustible materials, the power stays constant due to the technology of angled grates. After reaching a certain loading level, the fuel ignites with the help of hot air. Automatic ignition increases the device control comfort. Device operates with optimum emission values. You should prevent long lasting smouldering during the time of ember preservation, thus preventing the contamination of heat exchanger and chimney surfaces. In combination with the fire extinguishing equipment, loading of the boiler via the patented cell block and feeding stoker guarantees perfectly safe operation. With the help of the cell block, the combustion chamber is completely separated from the silo and the transport unit and represents patented protection from the return fire. The next advantage lies in cutting of large firewood by the cell block into smaller pieces, thus creating ideal combustion conditions. The circular skimming device for takeover of wood mass from the silo is appropriate for simple, unproblematic takeover of wood chips, wood pellets, wood shavings, sawdust and wood briquettes from the silo. Maximum stoker length is 6 m (max. weight of fuel = 250 kg/m3). The takeover device can be installed also in larger containers, provided that they do not require complete emptying. Two pretightened joint levers are equipped with rotating spring feathers which rotate and skim the wood mass onto the stoker. Material takeover takes place along the transverse and open transport stoker. In case of square and round containers (6 m diameter) emptying takes place with the transverse stoker. The loading system can be installed in different positions in 180 radius according to the option of the silo connection. These systems are described in details in technical brochures. Our experts will make a special offer with technical solutions which meet the customer's demands for each individual device.

GAS AND FUEL OIL HOT WATER BOILERS MODEL: STADLER ZV In these times, when the environmentally aware part of the world tries to lower the emissions of greenhouse gases into the environment, it is very important that the fossil fuels heating systems operate as efficiently as possible, with perfect combustion, and low fuel consumption. Our company already several years ago decided to actively contribute to the development of such heating devices with no impact to the environment. On the basis of 40 years of tradition in the field of boiler production and intensive investments into development, our company produced a new family of hot water boilers named STADLER ZV. These boilers are constructed on the triple draft principle with low Nox emissions. Due to the low load of the combustion chamber ( 1,2 MW/m3) and the conduction of flue gases through the pipe register, these boilers provide optimum combustion with top-class efficiency. s are made in accordance with Directive 97/23/CE PED and the Slovenian SIST EN12953 standard regarding gas or fuel oil burning. s are also equipped with a substantially dimensioned heat part. At the time of dimensioning of flame pipes, flue pipe packages and the water part, special attention was given to thermodynamic compliance and fast transfer of temperature to the water. s are also equipped with large volume water parts appropriate for optimum temperature control in different operating conditions. Inspection openings for entrance into the water part are easily accessible and allow easy access. s are well insulated and installed on a support frame. The operating overpressure is adapted to customer's demands. Our company produces boilers intended for pressures of 6-16 bars with the maximum operating mode of up to 160 C depending on the order or the investor's temperature mode. Minimum operating mode equals to 60 C. The external boiler fitting must provide protection of the hot water boiler against too low temperatures of the return tube.

Model Heating power kw power kw Weight kg BIOFLAMM HEATING SYSTEMS MODEL: TRB/VA This heating device comprises the pre-fireplace reactor TRB and the VA boiler. The combination of these two components is used everywhere where the combustion conditions are difficult due to the higher humidity or due to the problematic fuel. Bioflamm multi draft VA boilers are used as heat exchangers and places for flue gas burn down. s are equipped with two horizontal drafts and three vertical drafts routed through the pipe packages. The inspection-cleaning doors are positioned on the side of the boiler (top, bottom) and on the back side, thus allowing easy access. In especially tough operating conditions boilers are shielded with quality fireproof clay in the first draft. Large dimensioned drafts and vertical pipe packages provide this heat exchanger with low temperature flue gases and enable high efficiency. All larger boilers are equipped with walkable platforms with railings intended for cleaning and supply and with entrance and exit ladder. They are produced by welding certified quality sheet metal in accordance with DIN 4702 and 4751. The construction is made in accordance with TRD and all regulations and norms of SIST, EN-DIN and VGB. The production process is controlled by our experts as the company is certified in accordance with ISO 9001, module B and module D. Products are equipped with the CE 0036 marking. The standard version of boilers operates with overpressure of 3 bars and the operating temperature of the flow of 120 C. On special demand, boilers can also be produced for operation in tougher conditions (hot water boilers or low pressure steam boilers with powers of up to 6 MW, temperatures 140 C and operating pressure 4.5 bars). The automatic Bioflamm TRB pre-fireplaces with movable grates and automatic deashing enable the combustion of very problematic fuels. Reactors are constructed as a water-cooled pipe cage construction. The frame of the burner is shielded with quality fireproof clay A 40 or A 60, depending on the fuel the device is planned for. The quality movable transverse grates made of 24% chromed alloy ensure long service life and quality combustion on grates. Grates are installed next to each other, are simple, can be individually replaced, and form several movable grate layers. In case of extra humid, ash rich, or slag forming fuels, the Bioflamm degassing reactors with special air injection systems improve the combustion with their controlled combustion air fans. The primary air fan regulates the degassing process on the grate, whilst the secondary air fan enables combustion during the degassing of the formed flue gases. Separation from the fireplace and the boiler enables fast control in accordance with DIN 4751 Part 2. Reactors are produced in two construction versions; TRB N for humid fuels and TRB T for dry fuels. They are also equipped with the automatic cleaning and ash removing system. The exterior of the boiler can be installed with automatic deashing which transfers the ash into the ash container. The standard version of boilers operates with overpressure of 3 bars and the operating temperature of the flow of 120 C. On special demand, boilers can also be produced for operation in tougher conditions (hot water boilers with powers of up to 6 MW, temperatures 140 C and operating pressure 4.5 bars). In the past years, the company also developed an extra version of reactors marked TRB LK for connection of grain dryers or dryers of the sawdust accumulated during wood pellet production. Reactors are made of double-walled steel sheet frame where the air is directed into individual combustion zones. On the internal side, reactors are shielded with fireproof clay, whilst their external side is substantially insulated to prevent heat radiation into the environment. Grate movements and combustion air injection are similar to those of the basic version. The entire TRB/VA device is controlled by the Optimatika+ micro processing control via information received from the Lambda probe and temperature sensors. This control regulates the combustion process as well as the peripheral units from the takeover of the wood mass from the silo all to the cleaning of flue gases.

BIOFLAMM KURILNI SISTEMI MODEL: TRF-RK These boilers are appropriate for use where the biomass humidity cannot be controlled or where the humidity cannot be dried out and therefore remains very high. In the first and second draft, boilers are shielded with quality fireproof clay. The quality movable transverse grates made of 24% chromed alloy ensure long service life and quality combustion on grates. Construction allows to burn inferior and problematic humid wood residues which could previously not be used as fuel due to the excessive emissions of harmful substances in flue gases. s are equipped with a large combustion chamber with the first inversion of hot flue gases over the fuel where the first phase of fuel drying begins. The large quantity of fireproof clay radiates the temperature on the fuel which moves along the grate, thus drying it additionally. The front side of the fireplace is equipped with primary and secondary air fans. The air is conducted into the combustion process along a special system of channels and air injection nozzles, thus achieving swirling of flue gases and further increasing the combustion. The well-dimensioned second draft serves also for deposition of large particles of floating ash. fireplaces are equipped with horizontal heat exchangers. Three draft heat exchangers are equipped with channels for first inversion of hot flue gases, whilst the other two inversions take place through pipe packages. Large dimensioned drafts horizontal pipe packages provide the boiler with low temperature flue gases and high efficiency. s are produced by welding certified quality boiler sheet metal in accordance with DIN 4702 and 4751. The construction is made in accordance with TRD and all regulations and norms of SIST, EN-DIN and VGB. The production process is constantly controlled by our experts as the company is certified in accordance with ISO 9001, module B and module D. Additional quality control is provided by the company TÜV Sava Ljubljana and other institutions taking care for product quality control. s are equipped with thermal protection devices for protection against overheating. The horizontal heat exchanger pipes are cleaned pneumatically or in accordance with the special programme. The inspection-cleaning doors are positioned on the front of the boiler (top, bottom), thus allowing easy access for cleaning of horizontal drafts. They are also equipped with the automatic cleaning and ash removing system. The exterior of the boiler can be installed with automatic deashing which transfers the ash directly into the ash container. The standard version of boilers operates with overpressure of 3 bars and the operating temperature of the flow of 120 C. On special demand, boilers can also be produced for operation in tougher conditions (hot water boilers or steam boilers with powers of up to 10 MW, temperatures 160 C and operating pressure 10 bars). s are factory shielded with fireproof clay A 60, which is resistant to high temperatures. They are also equipped with a special system for the supply of primary and secondary air. The secondary air is conducted along special channels located in the body of the fireplace and directed with nozzles through the fireproof clay panelling into both drafts. Supply of the primary and secondary air is controlled via the continuously controlled fans. The entire device is controlled by the micro processing control via information received from the Lambda probe and temperature sensors. This control regulates the combustion process as well as the peripheral units from the takeover of the wood mass from the silo all to the cleaning of flue gases.

DEVICE CONTROL Controls with the Lambda probe Lambdamatika and Optimatika+ are installed in Rital cabinets which include all control elements for the entire system, continuous motor drives, protection of drive units, and the device for calling of 6 telephone numbers. On special order they can also be installed with modems for connection with the remote control. The cabinet is equipped with the main switch (depending on the supply power of electric motors) and the emergency switch. Doors of the cabinet are equipped with the microprocessor with a display and a keyboard for direct access into the combustion parameter setting program. Use of the program and the input of desired data is simple as the program allows scrolling with cursor keys and includes simple commands. The programme is made as a multi-level programme device operator level and repair or fine-tune expert level. VISUALIZATION The communication package for remote control of data and for the visualization of operation is used for control when the operator is out of the boiler room. The connection is established with the help of the modem and internet, or directly via the cable in case of small distances. In case of the cable connection, the visualization works trouble-free for 24 h, but demands an amplifier in case of distances greater than 200 m. Long-term connection via your telephone will cause disturbances during monitoring of current values due to the signal strength fluctuation. Significant data about device operation and reports of disturbances can be followed on the PC display. This way enables the operator-supervisor the access to all required data, which is why he can quickly react in cases of device malfunctioning. On the basis of these data, the supervisor makes corrective measures and adapts the operation to desired parameters. If the supervisor is unable to repair the malfunctioning he must immediately contact the manufacturer's service team which will take care for it with no major problems. With the permission of the investor, the manufacturer's service team can enter into the communication system. The visualization allows access to different levels of operation, depending on the data to be checked. All levels enable formation of excel charts and analyses of operation in individual time periods. Because this is a complex heating device, we recommend the operator to plan adequate maintenance interventions on the basis of number of hours of operation. COMPANY PRESENTATION OUR 150 YEARS Company WVterm from Maribor continues the TVT Boris Kidrič company's tradition in the field of boiler production. The beginning of industrial production reaches back in 1863 when the railway carriage and steam locomotive overhaul facilities were constructed. In 1970 the TVT Boris Kidrič, proizvodnja tirnih in cestnih vozil company signed a contract with the German STADLER company. Later, TVT became the biggest producer of boilers in the former Yugoslavia. Unfortunately, this big company could not avoid the crisis which appeared after the break-up of Yugoslavia. In 1995 an ownership transformation occurred and a new company WVterm was founded. During the past years, WVterm proved to be a vital export oriented company. The changed approach to work enabled better conditions in all fields of operation. The operation economics provides the company with a favourable business partner position. The company experienced rapid growth during the past years and today employs approx. 80 workers instead of the original 27. Due to the local conditions, export orientation was compulsory and today represents over 60% of all production. Our biggest partners come from the EU market. Besides the EU market the company is also present in the markets of the former Yugoslavia where the TAM STADLER trademark is still appreciated. Our perspective is built on experience upgraded with hard development work and with the aim to develop good products interesting for the market. With the internal and external potentials we significantly renewed and expanded our production programme. Efficiencies as well as low flue gas emissions and design of our products are now at the same level as the European competition. The conformity of products is guaranteed with the company s TÜV certificates which represent an integral part of documentation. One of the founding aims of the market appearance is to renew the old trademark that is to establish a positive contact with the market. We strive to restore the good name of the STADLER TVT trademark with hard work and quality production. Use of the trademark is protected both at home and abroad with number Z-9670961. Besides this trademark we are also present in the wood biomass market with Bioflamm and HDG Bavaria trademarks. The company provides HDG boilers in Slovenia and other countries of the former Yugoslavia. Company's production programme is very wide and with its Made in Slovenija products covers almost all areas of hot water boiler production. In the last years, the company increasingly invested in new technologies and has already caught up with technical development of its European competitors, thus keeping its competitiveness in the EU. During the last years, the welding technology was modernised with new pulse welding machines and robot welding of boilers and components. Preparation of boiler parts is based on top-class laser cutting of sheet metal and CNC technology for sheet metal and pipe forming. This technology helped us to achieve the production and productivity which is comparable with European competitors.

FIREWOOD HOT WATER CENTRAL HEATING BOILERS MODEL: STADLER TR STADLER TR firewood hot water central heating boilers provide comfortable and energy saving heating. Such heating is enabled with integration of the new innovative technology in the field of control and modern production technology. s are constructed for burning all types of wood and reach efficiencies of over 91%. Constant growth of fossil fuel prices and the increased care for the environment make this boiler even more important. By using different types of wood, even of different humidity, these boilers allow you to reach perfect combustion conditions. Emitted flue gases are harmless to the natural balance. You should load the boiler with ½ m long firewood as close together as possible, thus reaching uniform fuel structure and stable combustion conditions. Single load should be enough for several hours of operation. Fireplace volume equals to 150 l and can be loaded with up to 50kg of hardwood logs. Connection to the power supply is very simple, as the boiler includes already prepared wiring with plug equipped cables. By purchasing our boiler, you meet all of the requirements to obtain your government's subsidy. Construction of the boiler incorporated the modern degassing combustion technology. The flame is vertically directed through the burner nozzle with the help of the controlled injection of the primary and secondary air. When the flame enters the combustion chamber, it swirls and in touch with the red-hot combustion chamber causes the remaining not-combusted wood gases to burn at temperatures of approx. 1000 C. The control regulates the operation of the primary and secondary air step motors, thus supplying the combustion process with regulated quantities of air which enable the best combustion. The large panel shielded loading place protects the boiler from accumulation of tar and ensures long service life of the boiler. s can be loaded with firewood of up to 56 cm in length. The burner nozzle is made of chrome alloy which also significantly prolongs the service life of the boiler. 2 The fireproof clay combustion chamber is upgraded with the bottom made of high-temperature resistant concrete which guarantees complete combustion of wood gases. s are equipped with the Lambda probe, temperature sensor and continuously controlled electric motor of the fan.

FIREWOOD HOT WATER CENTRAL HEATING BOILERS MODEL: STADLER LT Due to their wood gas combustion technology, Stadler LT firewood hot water central heating boilers enable energy saving heating. s are constructed for burning all types of wood and reach efficiencies of over 90%. They are completely made in Slovenia, thus showing high level of expertise. Development of the product brought such improvement that our company was granted with the national patent by the Slovenian Intellectual Property Office. These hot water boilers are constructed for for burning of 56 cm, or 33 cm long firewood. You should load the boiler with firewood as close together as possible, thus reaching uniform fuel structure and stable combustion conditions. Single load should be enough for several hours of operation. Fireplace volume equals to 130 dm3 and can be loaded with approx. 35 kg of firewood. The container should be loaded with firewood to its top limit, while taking care not to load the firewood too close to each other as this could cause jamming. Modern control enables you to burn different types of wood and to reach ideal combustion conditions with flue gases which are harmless to the natural balance. These boilers are equipped with modern fireplaces with hot combustion chambers made of temperature resistant ceramics. The hot combustion chamber allows swirling combustion of wood gases resulting in the combustion of all combustible substances in flue gases.

FIREWOOD HOT WATER CENTRAL HEATING BOILERS MODEL: STADLER GT STADLER GT boilers belong to a new generation of firewood hot water heating boilers. With their wood gasification technology they enable modern and energy saving heating. They are constructed to burn all types of firewood of up to 54 cm or 33cm in length. Their combustion efficiency reaches over 90%. themselfs are designed and produced in Slovenia. By naming the product range STADLER we wished to show that the production is still active and adapts to new combustion conditions and techniques. In comparison with our boilers marked TR and LT, these boilers come with a simpler control. Nevertheless, they provide stable combustion processes enabled by the inovative construction. These boilers achieve excellent combustion parameters which are characteristic for wood gasification boilers. Quality production, controlled combustion process and high efficiency of these boilers beat the competition of the lower priced boilers by far. By using different types of wood, it is possible to achieve good combustion conditions in the boiler. Firewood burns in the lower part, whilst the supplied primary air leads the flame and wood gases downwards into the combustion chamber. When flue gases come through the burner nozzle, they are blown with controlled supply of secondary air. Flue gases mixed with the flame and fresh air swirl in the combustion chamber, and in touch with the red-hot fireproof clay, burn with extreme temperatures. The control regulates the combustion process via the temperature sensor in the chimney and sensors installed in the boiler and the accumulator. It also regulates the continuous control of the fan and the primary and secondary combustion air supply motor flap. Controlled supply of the combustion air enables low values of emmissions in flue gases which are significantly lower than the law regulated ones. s are equipped with an insulated hot combustion chamber made of fireproof clay which quickly reaches high temperatures and enables good combustion of wood gases. The efficiency boilers reache over 90% which points out the top-class echievement for boilers with lower level control without the Lambda probe. The hot combustion chamber enables the boiler to reach the optimal combustion Characteristics Unit GT 20 GT 30 process in only minutes. These boilers can be installed into systems equipped with hot water accumulators. We recommend the use of the heating system control because this is the only way to preserve different water layers in the hot water accumulator. Our boilers are in compliance with all currently valid provisions on safety and construction design (e.g. DIN 4751 B1.1, DIN 4702, etc.). They are tested for pressure and water tightness, factory equipped with a thermal protection device and can be installed in closed heating systems. The permissible operating pressure of boilers equals to 3 bars. We recommend the use of firewood with humidity of 25% which is achieved by drying it outdoors for 2 years. You should load the boiler with firewood as close together as possible, thus reaching uniform fuel structure and stable combustion conditions. Single load should be enough for several hours of operation. The volume of the fireplace is 105 dm3 and can be loaded with approx. 30 kg of firewood. You should load the container with firewood to the top of the doors, while taking care not to load them too close to each other as this could cause jamming.

WOOD PELLET HOT WATER CENTRAL HEATING BOILERS MODEL: STADLER PELET STAR Stadler PELET STAR hot water central heating boilers belong to a new generation of wood pellet boilers. They were designed by our company in cooperation with the Swedish company Ariterm. The BeQuem burner enabled the development of a completely automatic wood pellet boiler which guarantees reliable and safe operation with minimum cleaning and maintenance interventions. s are produced with the modern sheet metal treatment technique. Construction concepts provided the boiler with a touch of modern design, while respecting the ergonomic demands for the operation of the boiler. Construction of the boiler is produced in accordance with regulations DIN 4751 B1.1, DIN 4702, EN 303-5. s are equipped with the CE 0036 marking and can also be installed in smaller rooms to provide comfortable and energy saving heating. The side of the boiler is equipped with the weekly wood pellet silo, whilst the large ash chamber allows longer intervals between cleaning. Construction of boilers allows easy access to all internal surfaces and hence easier cleaning and maintenance. We recommend you to install your central heating system with a hot water accumulator which allows optimum boiler operation with low energy consumption (low-energy constructions and transition periods). In case of bigger consumption, the hot water accumulator amortizes the current lower burner operation capacity. Special construction of the BeQuem wood pellet burner allows reliable operation and high level of safety. Wood pellet feeding is arranged with a double stoker system where the lower stoker feeds wood pellets into the lower part of the combustion chamber. With such wood pellet feeding the ash is pushed further and the combustion chamber automatically cleaned. Such feeding technique makes the burner appropriate even with wood pellets of weaker quality which can now often be found on the market. Fire safety is ensured with temperature sensors and the cell block. Ignition and control of the flame are controlled with a special sensor.

WOOD PELLET HOT WATER CENTRAL HEATING BOILERS MODEL: STADLER EKO PELET Stadler EKO PELET hot water central heating boilers were designed with combination of firewood boilers and Swedish made burners. In this way boilers with the BeQuem wood pellet burners became automated units for heating of living quarters. Unlike the use of fossil fuels, the use of local energy resources, such as wood pellets, is harmless to the environment and decreases heating costs. These wood pellet boilers are equipped with a control which allows completely automated operation of the boiler without constant regulation. They regulate the supply of pellets from the container and the combustion process. s are also equipped with a pellet ignition device and flame control. The burner activates automatically as soon as the sensor in the boiler detects fall of water temperature bellow the preset value, and deactivates as soon as this temperature is reached. The volume of the factory offered wood pellet container equals to 0.6 m3 which is enough for approx. 10 days of operation. Alternatively you can order a larger container with volume of 0,93 m3. Our company also offers elements for the construction of even larger wood pellet containers which can be assembled in your boiler room or the room next to it. These boilers can easily be rearranged into firewood heating boilers by unscrewing the flange screws, removing the burner and turning it into the position which does not interfere with the operation of the boiler. Then, you have to install the cover over the burner on the external side of the boiler. Fix the cover firmly and prevent the flue gases from escaping. Cleaning of the boiler is also very simple. Open the lower door and remove the ash collected in the drawer. From time to time it is also necessary to check if the combustion chamber is clean. In case you notice any slag residue, remove it adequately. We do not recommend you to disassemble the burner during cleaning, however if this is necessary please call our authorised repair service centre. After each rearrangement of the boiler for burning firewood, clean the fireplace of the boiler and the space under the grate. The construction of the burner is equipped with a display showing mode of operation and temperature. Under the display, there are some arrow keys which enable you to scroll along the simple menu. With the use of these keys you can set the operation of the burner or simply control its operation. Calculation of the required boiler power m 2 cm 0,30 Apartment x Living quarters x Heat loss size height coefficient Poorly insulated buildings, shady and high altitude positions require the use of a heat loss coefficient of 0.40. In case of simpler heating systems we recommend you to install a special pump. This special pump with a three-way valve ensures that the boiler first reaches the temperature of 60 C and then only emits the excess energy into the system. During the cool down phase, the pump and the three-way valve ensure that the water temperature in the boiler does not fall below 55 C, thus preventing the formation of condensate. If the system includes a hot water accumulator, the three-way mixing valve allows the accumulator to be filled. With the use of the water accumulator, better operation can be achieved, especially during transition periods when temperatures are not too low. model Wood pellet boiler capacity kw Firewood boiler capacity kw / 860 = Required boiler power Electric connection 240 V 50 Hz Power consumption 240 V 50 Hz Efficiency EKO PELET 20 10-20 30 450 W 60 W 91,5 % EKO PELET 40 25-40 40 600 W 90 W 90,7 % WVterm d.o.o., Valvasorjeva 73, 2000 Maribor, Tel.: +386 2 429 28 10, Fax: +386 2 420 21 67, wvterm@wvterm.si 9

HOT WATER CENTRAL HEATING ACCUMULATORS MODEL: AT Hot water accumulators represent intermediate central heating elements and are used in modern heating systems. They are used for accumulation of the excess thermal energy produced by the boiler and for evenly regulated supply of energy to different consumers. Hot water accumulators are indispensable in systems with installed firewood, wood pellet, or wood chip heating boilers. Firewood heating boilers do not allow the complete control of power without significant interruption of the combustion process. Firewood combustion cycle brings excess thermal energy which consumers cannot use at that moment therefore it is conducted to the hot water accumulator. After the fuel has burnt and the heating elements cooled down, the automatic control takes care for transfer of hot water from the accumulator to heating elements. Our production programme includes hot water accumulators of various sizes: 500, 750, 1000, 1250, 1500, 1800, 2000, and 3000l. Accumulators are equipped with fittings for connection of heating circles, sensors and thermometers. The number of used fittings depends on the complexity of the planned heating system prescribed by the manufacturer at the time of sale of the product or by other professional subjects.

DUAL FIREPLACE FIREWOOD AND FUEL OIL CENTRAL HEATING BOILERS MODEL: STADLER TOBI Stadler TOBI central heating boilers are constructed as extremely energy saving boilers due to the installation of fuel oil and firewood boilers in a single construction. Both boilers use a single water reservoir, but completely separated fireplaces. Such design enables automatic rearrangement from burning of one type of fuel to another which cannot be achieved with combined boilers. s are basically intended for burning firewood in the 90/70 C operating mode. The fuel oil part of the boiler activates automatically after all of the fuel from the firewood fireplace has been used and the temperature dropped under the preset value. The fuel oil part of the boiler does not activate if the firewood fireplace is full and the preset temperature is reached. In case you deactivate the automatic system, these boilers only operate by burning firewood. A more modern construction concept classifies these boilers among the new generation of eco-friendly products as they operate in a similar way as hybrid cars. The firewood fireplace is equipped with modern burning in the lower side part of the boiler which enables controlled long burning process lasting even over 3 ½ h. The fireplace allows you to burn 33 cm long firewood. s are equipped with a return water preheating system and a cast iron grate which improves firewood combustion processes. Loading doors allow loading of large pieces of firewood. The special fireplace constructed for burning fuel oil is equipped with a hot combustion chamber and a turbulator in the third draft. Its design enables top-class efficiency of over 93%. Combusted flue gas emissions reach even more favourable parameters than required by law. The fuel oil part of the boiler is equipped with the SELTRON control. These boilers cannot be upgrades with domestic water heaters. Domestic water heaters can be installed as separated units which are then connected to the boiler. Ba purchasing the domestic water heater additionally, it is possible to control the temperature in the domestic water heater with the help of a pump. panelling is enamelled in the RAL 3000 or RAL 2004 colour combination. Our boilers are in compliance with all regulations regarding safety at work. Construction of the boiler is produced in accordance with regulations DIN 4751 B1.1, DIN 4702, EN 303-5, and is equipped with the CE 0036 marking. s are also equipped with a thermal protection device. The central heating system must compulsory include one of the system for lifting the return water as this is the only way to use the boiler with lower powers. If the boiler is not connected with the system for lifting return water the boiler condensates and causes poor combustion. This special pump with a three-way valve ensures that the boiler first reaches the temperature of 60 C, and emits only the excess energy into the system. At the same time it prevents the return water with temperatures lower than 55 C to enter the boiler, thus preventing the condensation. If the system includes a hot water accumulator, the three-way mixing valve enables the accumulator to be filled. With the use of the hot water accumulator, better operation of the burning device can be achieved, especially during the transition periods when temperatures are not too low, but still demand heating. model TOBI Power (fuel oil) kw Power (wood) kw Fireplace size dm 3 water quantity l Required draft Pa Weight kg Chimney Connection (fuel oil) Ø Chimney Connection (wood) Ø width mm height mm Required door width to enter the boiler with panelling into the room Required door width to enter the boiler without panelling into the room Efficiency (fuel oil) 20 15-20 20 86 105 15 230 130 160 990 1200 850 770 93,2 81,2 25 20-25 25 86 100 20 240 130 160 990 1200 850 770 93,4 81,5 % Efficiency (wood) % 16 WVterm d.o.o., Valvasorjeva 73, 2000 Maribor, tel.: +386 2 429 28 10, Fax: +386 2 420 21 67, wvterm@wvterm.si
FIREWOOD AND FUEL OIL HOT WATER CENTRAL HEATING BOILERS MODELS: STADLER EKOs and RLs These devices include two separate boilers. The basic boiler is the firewood boiler onto which the fuel oil boiler or gas oiler is installed. The firewood boiler is reinforced with two holders which enable safe installation of the fuel oil or gas boiler. Each boiler represents the best solution for itself as it is in compliance with all ecology standards. The boiler can additionally be upgraded with a separate domestic water heater, whilst the heating control takes place via the external control. Stadler EKOs heating boilers are constructed in accordance with new findings concerning wood combustion processes. Fireplaces are adapted for standard firewood lengths (33cm and 50cm). The construction of the fireplace also allows loading of somewhat longer logs. Permissible cutting length equals to +6 cm, thus enabling you to load the boiler with firewood of up to 40 or 56 cm in length. s EKOs 25 are to be loaded with 33cm long firewood, whilst boilers EKOs 30-40 are to be loaded with 50cm long firewood. s are designed for operation in the 90/70 C mode, whilst their return water preheating system improves the thermal load of the boiler. The new way of conduction of flue gases improves the combustion processes during firewood burning. Large loading doors enable easy loading of firewood into the fireplace. s can be loaded with large quantities of firewood, therefore we recommend you to burn your fuel in a downwards direction, thus prolonging the combustion time of a single load.

HDG Compact electronic control device of the boiler takes care for good combustion technology and is a product of our development programme. It can also be upgraded for control of different heating systems. All actual conditions of the operating device are shown on the display. Fuel loading takes place directly on combustion grates. Fuel supply and primary and secondary air can be adjusted independently. Even in case of bigger shares of non-combustible materials, the power stays constant due to the technology of angled grates. After reaching a certain loading level, the fuel ignites with the help of hot air. Automatic ignition increases the device control comfort. Device operates with optimum emission values. You should prevent long lasting smouldering during the time of ember preservation, thus preventing the contamination of heat exchanger and chimney surfaces. In combination with the fire extinguishing equipment, loading of the boiler via the patented cell block and feeding stoker guarantees perfectly safe operation. With the help of the cell block, the combustion chamber is completely separated from the silo and the transport unit and represents patented protection from the return fire. The next advantage lies in cutting of large firewood by the cell block into smaller pieces, thus creating ideal combustion conditions. The circular skimming device for takeover of wood mass from the silo is appropriate for simple, unproblematic takeover of wood chips, wood pellets, wood shavings, sawdust and wood briquettes from the silo. Maximum stoker length is 6 m (max. weight of fuel = 250 kg/m3). The takeover device can be installed also in larger containers, provided that they do not require complete emptying. Two pretightened joint levers are equipped with rotating spring feathers which rotate and skim the wood mass onto the stoker. Material takeover takes place along the transverse and open transport stoker. In case of square and round containers (6 m diameter) emptying takes place with the transverse stoker. The loading system can be installed in different positions in 180 radius according to the option of the silo connection. These systems are described in details in technical brochures. Our experts will make a special offer with technical solutions which meet the customer's demands for each individual device.

They are planned with a 3D construction technology which provides precise design of each part of the boiler. The modern construction design is based on the triple draft principle. Flue pipes are not equipped with turbulators. s are constructed in accordance with high environmental standards and are produced in standard versions for operation with 4 bars of overpressure. For higher pressures (>10 bar), modified construction is used. You can choose between 90/70 C and 110/90 C operating modes. The ideal construction and the flame pipe type of flue gas conduction provide optimum combustion with efficiency of over 95%. Such efficiency means almost perfect combustion with minimum flue gas emissions which is, at this time of environmental awareness, more and more important. Products are equipped with the CE 0036 marking. s are intended for burning liquid or gas fuels. Advantageous boiler dimensions allow installation in small areas. Operation of our boilers is good even in case of saccadic and oscillating loads.

GAS AND FUEL OIL HOT WATER BOILERS MODEL: STADLER ZV In these times, when the environmentally aware part of the world tries to lower the emissions of greenhouse gases into the environment, it is very important that the fossil fuels heating systems operate as efficiently as possible, with perfect combustion, and low fuel consumption. Our company already several years ago decided to actively contribute to the development of such heating devices with no impact to the environment. On the basis of 40 years of tradition in the field of boiler production and intensive investments into development, our company produced a new family of hot water boilers named STADLER ZV. These boilers are constructed on the triple draft principle with low Nox emissions. Due to the low load of the combustion chamber ( 1,2 MW/m3) and the conduction of flue gases through the pipe register, these boilers provide optimum combustion with top-class efficiency. s are made in accordance with Directive 97/23/CE PED and the Slovenian SIST EN12953 standard regarding gas or fuel oil burning. s are also equipped with a substantially dimensioned heat part. At the time of dimensioning of flame pipes, flue pipe packages and the water part, special attention was given to thermodynamic compliance and fast transfer of temperature to the water. s are also equipped with large volume water parts appropriate for optimum temperature control in different operating conditions. Inspection openings for entrance into the water part are easily accessible and allow easy access. s are well insulated and installed on a support frame. The operating overpressure is adapted to customer's demands. Our company produces boilers intended for pressures of 6-16 bars with the maximum operating mode of up to 160 C depending on the order or the investor's temperature mode. Minimum operating mode equals to 60 C. The external boiler fitting must provide protection of the hot water boiler against too low temperatures of the return tube. Equipment of the boiler can also include the system for protection against condensation. Good boiler insulation prevents heat loss into rooms and enables stable thermal operation. s are insulated with two layers of 60 mm thick Type ZV Heat power water quantity Transport weight Operating weight water side flue side Flue side volume width lengt height kw l 6 bar 16 bar 6 bar 16 bar mbar mbar m 3 B L H 800 800 1300 2250 2650 3550 3950 20 6,3 1,3 1350 2850 1650 1000 1.000 1800 2550 2950 4350 4750 55 6,7 1,6 1550 2900 1850 1500 1.500 3800 3500 4000 7300 7800 57 7,2 2,6 1750 3750 2000 2000 2.000 5000 5200 5800 10200 10800 52 8 3,2 1850 4150 2100 2500 2.500 6000 6500 7600 12500 13600 65 8,6 4,2 1950 4350 2200 3000 3.000 7200 6900 8200 14100 15400 84 9,8 5,1 2000 4600 2250 4000 4.000 8000 9100 10300 17100 18300 145 8,7 5,8 2100 5200 2350 5000 5.000 9500 10500 11800 20000 21300 120 11,5 6,3 2300 5500 2550 6000 6.000 11500 13600 16200 25100 27700 164 11,7 8,3 2550 5800 2800 7000 7.000 17500 19500 23000 37000 40500 170 12,5 8,8 2850 6775 3200 8000 8.000 19000 21500 25300 40500 44300 155 11,5 12,3 2900 7250 3250 9000 9.000 21000 24200 27600 45200 48600 167 13,2 14,7 3000 7600 3400 10000 10.000 22800 25100 28500 47900 51300 156 13,5 16,7 3100 7950 3500 12000 12.000 25500 27300 34500 52800 60000 172 12,5 19,4 3200 8150 3600 24 15000 15.000 28000 35000 43000 63000 71000 163 14 23,5 3400 8500 3800 WVterm d.o.o., Valvasorjeva 73, 2000 Maribor, tel.: +386 2 429 28 10, Fax: +386 2 420 21 67, wvterm@wvterm.si

WOOD RESIDUE, WOOD CHIP AND WOOD PELLET HEATING SYSTEMS BIOFLAMM Biomass is becoming more and more important economic factor as it enables energy independence and discontinuation of fossil fuel use which represent excessive impact on the environment. Due to the increasing prices of fossil fuels and financial country incentives for biomass equipment, investment into this equipment become very profitable in short-term. Our company has been producing boilers and biomass equipment for almost 30 years and has developed and still develops a wide range of products. Equipment is technologically adapted so it can be installed practically in every room, even in smaller boiler rooms which were planned for fuel oil boilers. The company strives for improvement of products, especially regarding the combustion technique, with solutions for combustion of chemically compromised wood residues and with the use of wide range of granulation and moisture. s are adapted also for burning wood pellets, thus allowing the use of biomass boilers even in cities, industrial facilities and other settlements. BIOFLAMM HEATING SYSTEMS MODEL: VE/SREB s are produced with the installed reactor with the step grate. They are produced by welding certified quality boiler sheet metal in accordance with DIN 4702 and 4751. Contraction is made in accordance with TRD and all regulations and norms of SIST, EN-DIN and VGB. The production process is controlled by our experts as the company is certified in accordance with ISO 9001, module B and module D. Products are equipped with the CE 0036 marking. In the first draft, boilers with integrated burner are shielded with fireproof clay A 40 or A 60, depending on the fuel the device is planned for. Construction of the boiler allows to burn wood residue with humidity of up to 45%. s are equipped with a large combustion chamber and well dimensioned first and second draft for deposition of large particles of floating ash. They are equipped with two horizontal drafts and three vertical drafts routed through the pipe package. The inspection-cleaning doors are positioned on the side of the boiler (top, bottom) and on the back side, thus allowing easy access. All larger boilers are equipped with walkable platforms and railings, intended for cleaning and supply, and with entrance and exit ladders. They are also equipped with the automatic cleaning and ash removing system. The exterior of the boiler can be installed with automatic deashing which transfers the ash directly into the ash container. At the flue gas exhaust it is necessary to install a fan and a flue gas deduster, thus achieving dedusting of up to 80 mg/m3. Where the demands are very strict it is necessary to additionally install electric or fabric filters. Fabric filters enable cleaning of dust particles of up to 10 mg/m3. The entire device is controlled by the Lambdamatik micro processing control via information received from the Lambda probe and temperature sensors. This control regulates the combustion process as well as the peripheral units from the takeover of the wood mass from the silo all to the cleaning of flue gases. The standard scope of micro processing control delivery includes the system for calling of 6 telephone numbers in case of standstill of any component of the device.

Model Heating power kw power kw Weight kg BIOFLAMM HEATING SYSTEMS MODEL: TRB/VA This heating device comprises the pre-fireplace reactor TRB and the VA boiler. The combination of these two components is used everywhere where the combustion conditions are difficult due to the higher humidity or due to the problematic fuel. Bioflamm multi draft VA boilers are used as heat exchangers and places for flue gas burn down. s are equipped with two horizontal drafts and three vertical drafts routed through the pipe packages. The inspection-cleaning doors are positioned on the side of the boiler (top, bottom) and on the back side, thus allowing easy access. In especially tough operating conditions boilers are shielded with quality fireproof clay in the first draft. Large dimensioned drafts and vertical pipe packages provide this heat exchanger with low temperature flue gases and enable high efficiency. All larger boilers are equipped with walkable platforms with railings intended for cleaning and supply and with entrance and exit ladder. They are produced by welding certified quality sheet metal in accordance with DIN 4702 and 4751. The construction is made in accordance with TRD and all regulations and norms of SIST, EN-DIN and VGB. The production process is controlled by our experts as the company is certified in accordance with ISO 9001, module B and module D. Products are equipped with the CE 0036 marking. The standard version of boilers operates with overpressure of 3 bars and the operating temperature of the flow of 120 C. On special demand, boilers can also be produced for operation in tougher conditions (hot water boilers or low pressure steam boilers with powers of up to 6 MW, temperatures 140 C and operating pressure 4.5 bars). The automatic Bioflamm TRB pre-fireplaces with movable grates and automatic deashing enable the combustion of very problematic fuels. Reactors are constructed as a water-cooled pipe cage construction. The frame of the burner is shielded with quality fireproof clay A 40 or A 60, depending on the fuel the device is planned for. The quality movable transverse grates made of 24% chromed alloy ensure long service life and quality combustion on grates. Grates are installed next to each other, are simple, can be individually replaced, and form several movable grate layers. In case of extra humid, ash rich, or slag forming fuels, the Bioflamm degassing reactors with special air injection systems improve the combustion with their controlled combustion air fans. The primary air fan regulates the degassing process on the grate, whilst the secondary air fan enables combustion during the degassing of the formed flue gases. Separation from the fireplace and the boiler enables fast control in accordance with DIN 4751 Part 2. Reactors are produced in two construction versions; TRB N for humid fuels and TRB T for dry fuels. They are also equipped with the automatic cleaning and ash removing system. The exterior of the boiler can be installed with automatic deashing which transfers the ash into the ash container. The standard version of boilers operates with overpressure of 3 bars and the operating temperature of the flow of 120 C. On special demand, boilers can also be produced for operation in tougher conditions (hot water boilers with powers of up to 6 MW, temperatures 140 C and operating pressure 4.5 bars). In the past years, the company also developed an extra version of reactors marked TRB LK for connection of grain dryers or dryers of the sawdust accumulated during wood pellet production. Reactors are made of double-walled steel sheet frame where the air is directed into individual combustion zones. On the internal side, reactors are shielded with fireproof clay, whilst their external side is substantially insulated to prevent heat radiation into the environment. Grate movements and combustion air injection are similar to those of the basic version. The entire TRB/VA device is controlled by the Optimatika+ micro processing control via information received from the Lambda probe and temperature sensors. This control regulates the combustion process as well as the peripheral units from the takeover of the wood mass from the silo all to the cleaning of flue gases. The standard scope of micro processing control delivery includes the system for calling of 6 telephone numbers in case of standstill of any component of the device. With additional payment it is possible to supply customers with a control for remote regulation and inspection of the combustion process and for the control of peripheral units. At the flue gas exhaust of the boiler it is necessary to install a flue gas deduster. Where the demands are very strict it is necessary to additionally install electric or fabric filters. Fabric filters enable cleaning of dust particles of up to 10 mg/m3.

DEVICE CONTROL Controls with the Lambda probe Lambdamatika and Optimatika+ are installed in Rital cabinets which include all control elements for the entire system, continuous motor drives, protection of drive units, and the device for calling of 6 telephone numbers. On special order they can also be installed with modems for connection with the remote control. The cabinet is equipped with the main switch (depending on the supply power of electric motors) and the emergency switch. Doors of the cabinet are equipped with the microprocessor with a display and a keyboard for direct access into the combustion parameter setting program. Use of the program and the input of desired data is simple as the program allows scrolling with cursor keys and includes simple commands. The programme is made as a multi-level programme device operator level and repair or fine-tune expert level. VISUALIZATION The communication package for remote control of data and for the visualization of operation is used for control when the operator is out of the boiler room. The connection is established with the help of the modem and internet, or directly via the cable in case of small distances. In case of the cable connection, the visualization works trouble-free for 24 h, but demands an amplifier in case of distances greater than 200 m. Long-term connection via your telephone will cause disturbances during monitoring of current values due to the signal strength fluctuation. Significant data about device operation and reports of disturbances can be followed on the PC display. This way enables the operator-supervisor the access to all required data, which is why he can quickly react in cases of device malfunctioning. On the basis of these data, the supervisor makes corrective measures and adapts the operation to desired parameters. If the supervisor is unable to repair the malfunctioning he must immediately contact the manufacturer's service team which will take care for it with no major problems. With the permission of the investor, the manufacturer's service team can enter into the communication system. The visualization allows access to different levels of operation, depending on the data to be checked. All levels enable formation of excel charts and analyses of operation in individual time periods. Because this is a complex heating device, we recommend the operator to plan adequate maintenance interventions on the basis of number of hours of operation. COMPANY PRESENTATION OUR 150 YEARS Company WVterm from Maribor continues the TVT Boris Kidrič company's tradition in the field of boiler production. The beginning of industrial production reaches back in 1863 when the railway carriage and steam locomotive overhaul facilities were constructed. In 1970 the TVT Boris Kidrič, proizvodnja tirnih in cestnih vozil company signed a contract with the German STADLER company. Later, TVT became the biggest producer of boilers in the former Yugoslavia. Unfortunately, this big company could not avoid the crisis which appeared after the break-up of Yugoslavia. In 1995 an ownership transformation occurred and a new company WVterm was founded. During the past years, WVterm proved to be a vital export oriented company. The changed approach to work enabled better conditions in all fields of operation. The operation economics provides the company with a favourable business partner position. The company experienced rapid growth during the past years and today employs approx. 80 workers instead of the original 27. Due to the local conditions, export orientation was compulsory and today represents over 60% of all production. Our biggest partners come from the EU market. Besides the EU market the company is also present in the markets of the former Yugoslavia where the TAM STADLER trademark is still appreciated. Our perspective is built on experience upgraded with hard development work and with the aim to develop good products interesting for the market. With the internal and external potentials we significantly renewed and expanded our production programme. Efficiencies as well as low flue gas emissions and design of our products are now at the same level as the European competition. The conformity of products is guaranteed with the company s TÜV certificates which represent an integral part of documentation. One of the founding aims of the market appearance is to renew the old trademark that is to establish a positive contact with the market. We strive to restore the good name of the STADLER TVT trademark with hard work and quality production. Use of the trademark is protected both at home and abroad with number Z-9670961. Besides this trademark we are also present in the wood biomass market with Bioflamm and HDG Bavaria trademarks. The company provides HDG boilers in Slovenia and other countries of the former Yugoslavia. Company's production programme is very wide and with its Made in Slovenija products covers almost all areas of hot water boiler production. In the last years, the company increasingly invested in new technologies and has already caught up with technical development of its European competitors, thus keeping its competitiveness in the EU. During the last years, the welding technology was modernised with new pulse welding machines and robot welding of boilers and components. Preparation of boiler parts is based on top-class laser cutting of sheet metal and CNC technology for sheet metal and pipe forming. This technology helped us to achieve the production and productivity which is comparable with European competitors.
