4 CENTRAL AIR HEATING, RESIDENTIAL HOME SUPPLY UNIT (HSU) Compact design Energy saving and high efficiency Standard dimensions Low maintenance Description The Home Supply Unit (HSU) is an indirect air treatment system. Heat released by, for example, a central heating system, district heating system or heat pump, is transferred to the air supply through an intermediate medium (water) in heat coils. The main advantages of an indirect system are comfort and low energy costs. The HSU is easy to apply in combination with under floor heating and solar heating along with radiators (to be installed later). This allows you flexibility in your choices, which is not the case with direct (gas) heating systems! Additionally, the self-regulating directcurrent fans only use half the energy used by traditional fans. Function The Home Supply Unit allows you the possibility to heat your home efficiently and comfortably with air treatment. By applying high efficiency heat coils, air filters, energy saving fans with the possibility of heat recovery, you choose the optimal comfort for your indoor climate. In combination with the Heat Recovery Unit (HR- WTW) you can easily supply clean air whilst discharging impure air. This allows an ultimate ventilation balance and a clean & healthy indoor climate as well as ensuring a direct reduction of your energy costs. With only one initial investment, the Home Supply Unit definitely offers you triple advantage of heating, ventilation and cooling your home. Technical specifications The HSU is constructed from durable, corrosion-proof and low maintenance coated materials and is grey in colour - RAL 7035/7036. The high quality, polished interior is thermally and acoustically insulated. This material is self-extinguishing and complies with Fire Classification B1, DIN4102. The HSU has a built in vibration free and noise reduction fan, which can be adjusted to different speeds. Supplied with: innovative intelligent regulators energy-saving direct-current fan (optional) heat coils with copper tubing and profiled aluminium grille applicable in combination with HR-WTW balanced ventilation >90% efficiency (optional) filtering for air purification applicable for low temperature heating cooling battery (optional) automatic moisture meter, remote control (optional) setup socket (optional) Models HSU (ST) standard HSU (EC) economic Heat Recovery Option: HR-WTW Every Home Supply Unit is easily supplemented with a heat recovery module. This module has the same design as the HSU and can be mounted on top. Both appliances become one design. The biggest advantage of the HR-WTW is optimal comfort with a high efficiency of >90%. The Home Supply Unit is available in 6 standard models of various versions, such as the Low Temperature version and the Up-flow or Downflow version.

5 HIGH EFFICIENCY HEAT RECOVERY HR- WTW Thermal efficiency >90% Energy saving of up to 400 m³ gas per year possible Balanced ventilation and air purifying Comfortable energy saving low maintenance Description The High Efficiency Heat Recovery Unit is specifically designed for well balanced ventilation with heat recovery and is perfectly suited for use in combination with the Home Supply Unit. Optimal balanced ventilation is created with this combination, which ensures a healthy and clean indoor climate with minimal energy loss. Function Insulation in buildings and homes has improved which now creates a necessity for improved ventilation and air quality management. Of course a good insulated home consumes less energy but also causes less possibilities for ventilation. Standaard Supplied with: cross flow heat exchanger for heat recovery and condensation discharge balanced ventilation filtering for purification of fresh air supply noise reduction, cross current ventilator with suspended blades balanced air dampers for recirculation By installing heat absorbing glass, modern insulation materials and following modern building techniques, houses are constructed in accordance with the strict Energy Performance Standard (EPN). Compliance as per the Standards stated in Machine Directive 89/336 EC (attachment 2B) and the Low Voltage Directive 73/23/EEC. Due to these restrictions, humidity levels, dust particles and CO 2 emissions will rise higher than the accepted values. It is now become a necessity for constant ventilation in housing following the balanced ventilation principle. This principle implies that extracted and supplied air should be controlled, as specified in NEN The HR-WTW utilizes the heat emitted from the impure, extracted air to warm the clean external air supply. Both airflows remain strictly separated by a cross current converter. This converter transfers 90% of the warmth which makes the reheating of ventilated air no longer necessary. Energy savings of approximately 400 m³ gas per year is possible. In addition, the fresh air is filtered (filter class G3) to ensure only clean air is supplied. Technical specifications The HR-WTW is constructed from durable, corrosion-proof and low maintenance coated materials and is grey in colour - RAL 7035/7036. The high quality, polished interior is thermally and acoustically insulated. This material is self-extinguishing and complies with Fire Classification B1, DIN4102.

8 AIR HEATING > AIR CIRCULATION UNIT / DESTRATIFICATION ES-2 Saving on energy costs Functions independently Applicable in combination with (in)direct fired air heaters Simple and efficient Description The ES-2 reduces energy costs in a very effective way and is particularly effective in high spaces. Transmission loss results in escaped energy, for example, through the roof. The ES-2 forces the rising, heated air back down. This results in a smaller area in which heat is suspended like a warm blanket. The ES-2 provides a direct contribution to the energy savings in a very efficient way. Function By lowering the rising, heated air you directly save energy by needing less heat. The fitted thermostat operates the unit when the set temperature has been reached. The unit only functions, therefore, when the effective temperature is reached at high level. In addition to saving energy this system of operation ensures the unit does not run unnecessarily and reduces humidity. Air is distributed effectively by way of an adjustable double deflection outlet grille. For optimum performance the ES-2 unit should be mounted at a maximum height of 8 metres. Technical specifications The ES-2 is constructed from durable, corrosion-proof and low maintenance coated panels and is grey colour - RAL 7035; other colours on request.

40 VENTILATORS HIGH EFFICIENCY DIRECT DRIVEN CENTRIFUGAL FANS DDEC Air volume from 350 to 4500 m³/h Energy saving Speed controllable Extremely silent operation Energy Saving With these new generation DDEC high efficiency fans you never use more energy than necessary. This brushless direct current motor in combination with electronic regulation utilises far less energy than conventional motors. These constant volume fans have a high efficiency rating of 70-80% at any speed. Define the energy saving? See NEN NEN Function Fan regulation lowers the speed and torque of the motor to the actual pressure loss, which causes the low energy usage. In these situations a conventional motor goes to the working point where the ventilation curve and system curve cross each other, which results in higher energy usage.

51 AIR HANDLING, AIR TREATMENT CABINETS LBK - CONCEPT Sandwich panel-construction Air volume from 100 to m³/h Cooling / heating / heat recovery / humidifying / mixing / ventilation Customised according to your specifications Three construction methods with maximum flexibility Description The importance of a comfortable indoor climate is often underestimated. As producers of air handling units, we can supply any concept of air handling and climate control equipment that is required. Ventilation, heating, cooling, humidifying, dehumidifying and heat recovery are some of these possibilities. Welded frame- construction For heat recovery we utilise high efficiency cross flow heat exchanger, twin coil systems, heat wheels and heat pipes. Also possible is StatiqCooling, a new energy saving method of cooling with water without a cooling machine. Every air handling unit can be assembled according to your wishes, without being bound to measurements. Our staff will be happy to inform you of the possibilities. Air volume, process, external resistance, filters, dimensions, sound, energy use etc. will all be taken into consideration to help you make your final choice. Pentapost- construction To realise this, we at Thermo Air, have designed three construction types to produce air handling units for every process. A. Welded frame- construction B. Pentapost- construction C. Sandwich panel-construction Every construction method has its own specific application areas. As standard, we have designed a number of modules with which we can build up our air handling units. The process determines which construction method and module should be applied. With these models and dimensions, we can provide you with any type of airhandling unit you require. Given its air volume and matching dimensions, the 30SP type is a speciality product that is only available on request. Pentapost- construction Thermo Air - Product Catalogue Edition

52 LBK - CONCEPT Construction types A. Welded frame-construction Constructed of a fully welded frame with single walled or double walled insulated plating. Sendzimir galvanised plating material is applied as standard. Available in pre-coated colours such as RAL 9010, 9001, 7035, other colours available on request. This construction method is frequently used for ventilation and industrial heating processes such as spraying cabinets or oil/gas fired air heaters. C. Self supporting sandwich-construction Completely manufactured from self supporting sandwich panels (with a standard width of 40 mm). This construction type is suitable for larger air volumes and dimensions, as well as special application ranges. The self supporting PIR/PUR panels have a closed cel structure and are galvanised on both sides with an RAL 7035 polyester coating. Other colours are available on request. The welded frame construction guarantees you a robust and sturdy air handling unit. A significant advantage of this construction type is the availability of practical modules. This construction is suitable for indoor and outdoor installation. All sandwich panel constructed units are single, complete units. They are therefore applied in the larger and more complex air handling units. Sandwich panels are available in various panel widths. B. Aluminum pentapost-construction Aluminium angle profile with single or double walled insulated plating, with an insulation width of 20 to 50 mm. The galvanised steel plating material is supplied standard in the colour RAL It is also available in pre-coated panels in the colours RAL 9010 and 9001 or customer specific colours.
