ICONS Domestic Hot Water production (D.H.W.) Heating Water Production grey STOCK AVAILABILITY STOCK AVAILABILITY Grey highlighted products are available in stock and can be dispatched in 1-5 working days. GUIDE WHEN CHOOSING A CALORIFIER A calorifier is an indirect water heating appliance (i.e. one that features at least one heat exchanger) which accumulates heat so as to handle consumption rates that may vary greatly over a period of time, while also limiting the power used by the generators. Cordivari offers a wide and varied range of calorifiers, thermal storage and heating components, to provide the most suitable product to any need and also allow simultaneous use of more energy sources. Calorifiers with traditional boilers: These products are designed for use with conventional boilers which use water as a heating medium in a sealed or open expansion circuit. The heat exchangers are designed to handle high flow rates on the primary side to ensure that the heat transfer will be efficient while at the same time avoiding excessively low return water temperatures. Calorifiers with biomass boilers: The selection of a calorifier while operating in conjunction with a biomass boiler must take account of fact that excessively low return water temperatures could reduce the lifespan of the boiler. In addition, a calorifier with a larger accumulation volume than normal will be more suitable as it will act as a buffer which will be beneficial to the biomass boiler. Calorifiers with condensing boilers: Condensing boilers are highly efficient and ecologically friendly. They operate at optimum performance when the flow water temperature is limited which results in the return water temperature being as low as possible. This will ensure that the latent heat is extracted out of the combustion products which will maximise the efficiency of the system. Calorifiers with solar systems: The heat exchange coil surface area is a critical issue when interfacing solar thermal systems with calorifiers due to limited primary flow rates and temperatures. The calorifier must also be capable of acting as a buffer to harness the solar energy throughout daylight hours. Calorifiers with heat pumps: Calorifiers operating in conjunction with airto-water or water-to-water heat pumps must have extremely oversized heat exchange surface areas to ensure that heat exchange will take place even when there is a limited difference in temperature between the primary circuit and secondary stored water. This will maximise the COP (coefficiency of performance) of the heat pump. Calorifiers with steam boilers: The use of saturated steam as a heating medium to produce domestic hot water, although little used in the housing sector, is a solution which is still employed in industrial environments where the steam is already in use for the manufacturing process. Technically speaking, steam calorifiers are characterized by relatively small heat exchangers, as on one hand the steam gives high heat exchange coefficients and on the other hand the exchangers usually operate with considerable differences in temperature between the primary and secondary circuits. The use of steam demands a more stringent safety regeime than the use of low pressure hot water systems as steam boilers, depending on their capacity and design pressures, are classified as higher risk and therefore must comply with the European Pressure Equipment Directive. Domestic hot water production (D.H.W.) Calorifiers operating with more than one energy source The demand to heat a calorifier using more than one energy source, while at the same time keeping the various circuits separate, has become much more common in recent times with the advent of renewable technologies which usually need to be backed-up with conventional boilers. In these cases, calorifiers with a number of heat exchangers are used with the design ensuring that excellent thermal stratification will be achieved with minimal interference between the various heat sources. Calorifiers operating with renewable energies D.H.W. production system connected to renewable energies, exploiting natural resources coming from air, water and ground. Calorifiers operating with electrical power Cordivari products designed for working with electricity can be connected to A/C power supply. Combined with a renewable energy power supply system (fotovoltaic, wind energy, and so on), it allows to have an environmental friendly system. GUIDE WHEN CHOOSING STORAGE A storage tank is a well insulated tank that is inserted in heating systems powered by a biomass generator. It has the dual function of allowing the generator to operate in a regular manner, restricting the number of stoppages, and of creating a thermal stabiliser for the heating system, thus improving working comfort considerably. Cordivari offers a wide range of storage tanks, which include both standard versions and a number of combined versions to be used as a single appliance, acting both as a storage tank and to produce domestic hot water. Central heating systems with one or more boilers which are plumbed together and do not generate domestic hot water. Central heating systems with one or more boilers which are plumbed together in conjunction with solar power which is connected to either one or two coil type heat exchangers. Domestic hot water is not generated in these tanks. Heating systems with one or more sources hydraulically divided, with the exploitation of the solar power and without DHW production. These are heating systems powered by a biomass generator or more generators that are hydraulically divided. The preparation of the DHW is done without involving the hot water storage tank. + + + Combined central heating system and domestic hot water production with one or more boilers which are plumbed together.

EXTRA1 - HEAT EXCHANGERS TECHNICAL DATA Cordivari heat exchangers, with tubes bent to the bottom, are able to heat the complete quantity of volume in an homogeneus way. Energy storaging is therefore improved and Ignition time data have to be referred to the complete volume of the tank, while in traditional straight heat exchangers equipped calorifires, a range between 9-17% of volume remains cold. t2 T1 T2 t1 CURVED HEAT EXCHANGERS Maximum power exchange (kw) with primary Ignition time (minutes) from 1 C to t2 and DHW continuous production lt/h within 1-45 at T1, secondary within 1-45 C and primary at T1 C and primary at T1 constant use of DHW production T1/t2 T1 T1 55/5 65/6 7/6 8/6 55 65 7 8 55 65 7 8 2 113 147 113 148 77 12 49 65 7,3 5,8 11,5 8,9 13,7 1,5 18 13,9 178 141 283 218 338 258 455 344 3 112 145 113 146 76 12 48 65 11,1 8,9 17 13,8 21 16,3 28 21,6 274 219 435 339 52 42 71 534 5 139 18 14 181 96 125 6 8 15 12,1 23,8 18,7 28,5 22,1 38 29,4 369 297 587 46 72 545 947 725 8 146 186 147 188 11 13 64 83 23 18 36 29 44 34 59 46 57 465 98 721 187 854 1465 1136 1 128 157 128 157 86 17,9 54 69 33 27 53 43 63 51 86 69 814 687 139 177 1571 1281 2127 1711 15 12 145 119 146 82 1 51 64 51 44 81 68 98 81 133 18 1256 175 222 1687 2428 28 329 2684 2 121 146 122 147 83 11 52 65 69 59 111 93 133 111 18 148 1699 1465 2738 232 3288 2741 4453 3665 25 118 145 119 146 81 11 51 65 84 71 134 111 16 131 216 174 266 1755 339 2734 3964 3244 5352 4314 3 128 456 127 157 87 11 55 7 1 84 159 13 19 154 255 24 2461 282 3926 3224 4694 3817 6321 553 4 126 159 127 161 87 112 56 73 131 11 27 168 247 198 33 26 3236 2718 5121 4151 615 493 8168 6443 5 137 138 96 61 162 253 31 41 3992 627 745 9921 176 179 125 82 135 24 239 312 3332 549 5923 7727 PRESSURE LOSS - CURVED HEAT EXCHANGERS 2 18 16 Chart for surfaces of:,5 m 2 /,75 m 2 / 1 m 2 Flow Rate [lt/min] 1 2 3 4 5 6 7 8 9 1,5 m 2 18 16 6 5 Chart for surfaces of: 1,5 m 2 / 2 m 2 / 3 m 2 Flow Rate [lt/min] 5 1 15 2 25 3 1,5 m 2 5, [mm H 2 O] 14 12 1 8,75 m 2 14 12 1 8 [mbar] [mm H 2 O] 4 3 2 m 2 3 m 2 4, 3, [mbar] 6 1 m 2 6 2 2, 4 4 1 1, 2 2, 2 4 6 8 1 12 14 16 18 1 2 3 4 5 6 Flow Rate [m 3 /h] Flow Rate [m 3 /h] INCREASED STORAGE CAPACITY OF CURVED ANTILEGIONELLA HEAT EXCHANGER Storage volume: Standard heat exchanger Storage volume: Heat exchanger for 1% heated volume Advantage in storaged volume Advantage in percentage [litres] [litres] [litres] [%] 2 165 19 25 13% 3 251 285 34 12% 5 438 485 47 1% 8 694 79 96 12% 1 97 995 88 9% STANDARD HEAT EXCHANGER 1% VOLUME HEATED WITH Antilegionella HEAT EXCHANGERS 16

Energy storaging is therefore improved and Ignition time data have to be referred to the complete volume of the tank, while in traditional straight heat exchangers equipped calorifires, a range between 9-17% of volume remains cold. t2 T1 T2 t1 ANTILEGIONELLA CURVED HEAT EXCHANGERS 15 2 25 3 4 Ignition time (minutes) from 1 C to t2 and primary at T1 PRESSURE LOSS - CURVED HEAT EXCHANGERS Maximum power exchange (kw) with primary at T1, secondary within 1-45 C and constant use of DHW production DHW continuous production lt/h within 1-45 C and primary at T1 T1/t2 T1 T1 55/5 65/6 7/6 8/6 55 65 7 8 55 65 7 8 125 125 85 54 51 81 98 133 1256 222 2428 329 152 152 15 67 44 68 81 18 175 1687 28 2684 123 123 84 53 69 111 133 18 1699 2738 3288 4453 148 148 13 65 59 93 111 148 1465 232 2741 3665 134 134 92 58 69 111 133 18 1699 2738 3288 4453 164 164 114 73 59 93 111 148 1465 232 2741 3665 13 13 9 57 1 159 19 255 2461 3926 4694 6321 162 162 113 73 84 13 154 24 282 3224 3817 553 133 133 92 59 131 27 247 33 3236 5121 615 8168 17 17 119 77 11 168 198 26 2718 4151 493 6443 Heat exchanger surface [m 2 ] 15 3 2 4 25 5 3 6 4 8 Chart for surfaces of: 3 m 2 Flow Rate [lt/min] 5 1 15 2 25 3 6 5 5, 4 4, [mm H 2 O] 3 3 m 2 3, [mbar] 2 2, 1 1,, 2 4 6 8 1 12 14 16 18 Flow Rate [m 3 /h] Chart for surfaces of: 4 m 2 Flow Rate [lt/min] 5 1 15 2 25 3 35 4 5 Chart for surfaces of: 5 m 2 Flow Rate [lt/min] 5 1 15 2 25 3 35 4 5 45 45 45 45 4 4 4 4 35 35 35 35 [mm H 2 O] 3 25 2 4 m 2 3 25 2 [mbar] [mm H 2 O] 3 25 2 5 m 2 3 25 2 [mbar] 15 15 15 15 1 1 1 1 5 5 5 5 5 1 15 2 25 Flow Rate [m 3 /h] 5 1 15 2 25 Flow Rate [m 3 /h] 2

Energy storaging is therefore improved and Ignition time data have to be referred to the complete volume of the tank, while in traditional straight heat exchangers equipped calorifires, a range between 9-17% of volume remains cold. t2 T1 T2 t1 UPPER STRAIGHT HEAT EXCHANGERS 2 3 5 8 1 15 2 25 3 4 5 Maximum power exchange (kw) with primary at T1, secondary within 1-45 C and constant use of DHW production T1/t2 T1 T1 Ignition time (minutes) from 1 C to t2 and primary at T1 DHW continuous production lt/h within 1-45 C and primary at T1 55/5 65/6 7/6 8/6 55 65 7 8 55 65 7 8 57 57 39 25 7 11 14 18 179 283 339 456 74 75 52 33 6 9 11 14 142 219 259 344 57 57 39 25 11 18 21 28 275 436 521 72 73 73 52 33 9 14 16 22 22 34 43 535 52 52 36 23 23 37 44 59 573 911 19 1468 66 55 46 3 19 29 35 46 468 724 857 1139 62 62 42 27 33 53 64 86 817 1312 1573 2129 75 76 53 34 28 44 52 69 69 179 1284 1715 8 8 55 35 32 51 61 82 783 1252 151 229 1 1 7 45 26 41 48 65 647 18 1198 1599 68 68 47 3 51 82 98 133 1259 226 243 3295 82 83 57 37 44 68 81 19 177 169 211 2687 7 7 48 3 69 111 133 18 172 2741 3293 4463 84 85 59 37 59 93 111 148 1468 236 2744 3668 59 59 4 25 84 134 16 216 269 3313 3969 5358 71 72 5 32 71 111 131 174 1758 2738 3249 4318 71 72 49 31 1 159 19 255 2465 3931 4698 6325 88 89 62 4 84 13 154 24 286 3229 3821 557 71 72 5 32 131 27 247 33 3242 5126 6112 8179 89 9 63 41 11 168 198 26 2723 4167 499 6448 78 78 54 35 162 253 31 4 3998 6275 7459 9924 99 1 71 46 135 24 239 312 3338 555 593 7735 t2 T1 T2 t1 CURVED HEAT EXCHANGERS 2 3 5 8 1 15 2 25 3 4 5 Maximum power exchange (kw) with primary at T1, secondary within 1-45 C and constant use of DHW production T1/t2 T1 T1 Ignition time (minutes) from 1 C to t2 and primary at T1 DHW continuous production lt/h within 1-45 C and primary at T1 55/5 65/6 7/6 8/6 55 65 7 8 55 65 7 8 113 113 77 49 7,3 12 14 18 178 283 338 455 147 148 12 65 6 9 11 13,9 141 218 258 344 112 113 76 48 11 17 21 28 274 435 52 71 145 146 12 65 9 14 16 21,6 219 339 42 534 9 9 62 39 23 37 44 59 571 99 188 1467 114 115 8 51 19 29 35 46 466 722 856 1137 11 11 69 44 33 53 64 86 815 131 1572 2128 124 125 86 55 28 44 52 69 688 177 1282 1712 82 83 56 36 51 82 98 133 1257 224 2429 3293 11 1 69 44 44 68 81 18 176 1689 21 2685 12 119 82 51 51 81 98 133 1256 222 2428 329 145 146 1 64 44 68 81 18 175 1687 28 2684 121 122 83 52 69 111 133 18 1699 2738 3288 4453 146 147 11 65 59 93 111 148 1465 232 2741 3665 118 119 81 51 69 111 133 18 1699 2738 3288 4453 145 146 11 65 59 93 111 148 1465 232 2741 3665 128 127 87 55 1 159 19 255 2461 3926 4694 6321 456 157 11 7 84 13 154 24 282 3224 3817 553 126 127 87 56 131 27 247 33 3236 5121 615 8168 159 161 112 73 11 168 198 26 2718 4151 493 6443 137 138 96 61 162 253 31 41 3992 627 745 9921 176 179 125 82 135 24 239 312 3332 549 5923 7727 26

EXTRA3 - HEAT EXCHANGERS TECHNICAL DATA Cordivari heat exchangers, with tubes bent to the bottom, are able to heat the complete quantity of volume in an homogeneus way.

Calorifiers for HEAT PUMP Cordivari Srl is constantly investing in the research of the best solutions for all innovative installations. Heat pumps heating systems are among the most advanced applications in terms of efficiency, energy-saving and sustainability and the production of domestic hot water (DHW) is a crucial factor of the proper functioning of such installations. Therefore a calorifier expressly conceived for heat pump systems is a key element in order to maximize the efficiency, the performances, the comfort of use while extending the generator lifecycle. The need to fulfil all these new challenging applications has lead to the extension of the range of Cordivari calorifiers for heat pumps. 142

NEW BOLLY PDC RANGE PATENTED HEAT-EXCHANGE MODULE Bolly PDC is the result of a continuous research aimed to develop a calorifier unique in its field. It is in fact the only patented system of thermal exchange actually on the market, specifically conceived for installation and heat pumps of latest generation. The exchange and stratification system is conceived to self-balance: only part of the heated water, proportionate to the temperature achieved during the thermal exchange, is inserted in the tank from the top. This way the water inserted in the upper part is at maximum desired temperature while fresh water coming from the lower part of the tank goes to the exchanger. This lead to many advantages such as the increased efficiency of the heat pump C.o.p, the achievement of a perfect thermal stratification, that allows to profit immediately of the heated water. This also allows to heat only part of the tank reducing energy waste. The innovative Bolly PDC, combined with an heat pump and thanks to the new patented exchange group is able to guarantee 3 % higher performances compared to a generic, traditional calorifier in terms of ignition time and thermal exchange efficiency. Laboratory tests and researches conducted on the stratification process confirm the use of Bolly PDC in a heat pump installation means an increased comfort and about a 15% reduction of electric consumption while extending the generator lifecycle reducing its turning on/off. 5 l.

ECO COMBI 1 PDC MULTI-HEAT ENERGY BUFFER FOR HEAT PUMP WITH 316L STAINLESS STEEL DHW CORRUGATED PIPE APPLICATION Heating hot water storage and D.H.W. production. MATERIAL BUFFER TANK: made in mild steel outside painted. There is no need of any anti-corrosion treatment due to the fact that the buffer is in a closed circuit without any adding air. DHW STORAGE: 316L stainless steel corrugated pipe, suitable drinkable water according to D.M. n. 174 dated 6.4.4. TECHNICAL DESCRIPTION Multi-heat Energy tanks EcoCombi 1 are used in units with a typically discontinuous energy source for double use: heating system and domestic hot water. Heating system with a biomass generator as energy source, combining the possibility to produce domestic hot water. In such case, storage heating volume allows the generator to regularly work, limiting number of stops due to the inadequate energy request of the heating system. Moreover, it limits the emission of smoke and creation of corrosive condensate (smokes side). In this system, the high potentiality of the Eco Combi allows to obtain a good DHW production, even if temperatures of the primary system are not so high (e.g. using heating pumps as primary source and solar source as support). The particular shape of the corrugated pipe is avoiding any problem relating to the DHW storage and ensure high heating exchange performances.

ECO-COMBI 1 MULTI-HEAT ENERGY BUFFER WITH 316L STAINLESS STEEL D.H.W. CORRUGATED PIPE APPLICATION Heating hot water storage and D.H.W. production. MATERIAL BUFFER TANK: Mild steel construction with exterior paint. No anti-corrosion treatment required due to the buffer s closed circuit system. D.H.W. STORAGE : 316L stainless steel corrugated pipe, suitable for drinkable water according to D. M. n. 174 dated 6.4.4 TECHNICAL DESCRIPTION Heating system with a biomass generator as energy source, combining the possibility to produce hot water for sanitary use. In such case, storage heating volume allows the generator to regularly work, limiting number of stops due to the inadeguate energy request of the heating system. Moreover, it limits the emission of smoke and the creation of corrosive condensate (smokes side). Domestic hot water production systems for domestic and sanitary use where heating water is stored. In this system, the high potentiality of the Eco Combi allows to obtain a good production of hot sanitary water even if temperatures of the primary system are not so high (i.e using heating pumps as primary source and solar source as support) The particular shape of the corrugated pipe is avoiding any problem relating to the storage of sanitary hot water and ensure high heating exchange performances.

STORAGE : 316L stainless steel corrugated pipe, suitable for drinkable water according to D. M. n. 174 dated 6.4.4. HEAT EXCHANGER: 1 fixed heat exchanger. TECHNICAL DESCRIPTION Multi-Heat Energy tanks EcoCombi 2 are used in units with a typically discontinuous energy source for double use: heating system and sanitary hot water system. Heating system with a biomass generator as energy source, combining the possibility to produce hot water for sanitary use. In such case, storage heating volume allows the generator to regularly work, limiting number of stops due to the inadeguate energy request of the heating system. Moreover, it limits the emission of smoke and the creation of corrosive condensate (smokes side). Domestic hot water production systems for domestic and sanitary use where heating water is stored. In this system, the high potentiality of the Eco Combi allows to obtain a good production of hot sanitary water even if temperatures of the primary system are not so high (i.e using heating pumps as primary source and solar source as support). The particular shape of the corrugated pipe is avoiding any problem relating to the storage of sanitary hot water and ensure high heating exchange performances.

OPEN EXPANSION VESSEL 34 STAINLESS STEEL / GALVANIZED / POLYETHILENE STAINLESS STEEL BOLLYTERM EXTRA- BOLLY Opened Expansion tanks are used as safety accessories in the heating systems where, due to legal reason it is forbidden to install closed expansion tanks systems. In Italy, for the water fireplaces, they are still one of the most simple and economic solution. Expansion tank is composed by a cover unit where all the security piping of outlet pipe for too full, supplying and systems charge, should arrive. Its rule is to merge the water in excess due caused by temperature increase. Expansion Tank should be placed on the highest point reached by the water and should have an expanding volume not less than the expansion volume developed by all the water contained into the system, whose value should be declared in the project. Expansion volume needed in the system is calculated by the following formula: Ve = C x e Where C is the water contained into the system and e is equal to the difference between the expansion factor of the water at the minimum conceivable temperature with sleeping system and the expansion factor of the water at boiling temperature of atmospheric pressure. Considering the first water temperature equal to 1 C and the boiling one at 1 C e =.431 It is possible to connect more than one tank together.

Furthermore, the tanks are located near uses characterised by highly variable air requirements in order to limit pressure fluctuations along the distribution lines. Optimum tank volume in a production system depends on the type of compressor, environmental conditions of operation and type of use. In systems characterised by max operating pressure of 1 bar and flow rates from 1 to Tank 1 Nm3/min, tank capacity is calculated, as a first approximation, with the following relationship: V=.2 to.6 Q V = theoretical volume of the tank in m 3 Q = intake flow rate from the compressor in m 3 /min.2 = coefficient for large plants.6 = coefficient for small plants MULTIFUEL ENERGY CYLINDERS - PUFFER HYDRONIC INERTIAL WATER PRESSURE COMPRESSED AIR RECEIVERS Pre filter Services ACCESORIES AND SPARE PARTS Filters Compressor Draining Air Dryer Drain Treatment TECHNICAL SUPPORT The following schemes are purely illustrative.

EXTRA- BOLLY BOLLYTERM STAINLESS STEEL FOR HEAT PUMP MULTIFUEL ENERGY CYLINDERS - PUFFER HYDRONIC INERTIAL WATER PRESSURE COMPRESSED AIR RECEIVERS Tank Pre filter Services Filters Air Dryer Compressor Draining Drain Treatment The following schemes are purely illustrative. To realize the installation, always refer to a qualified design engineer. Furthermore, the tanks are located near uses characterised by highly variable air requirements in order to limit pressure fluctuations along the distribution lines. Optimum tank volume in a production system depends on the type of compressor, environmental conditions of operation and type of use. In systems characterised by max operating pressure of 1 bar and flow rates from 1 to 1 Nm3/min, tank capacity is calculated, as a first approximation, with the following relationship: V=.2 to.6 Q V = theoretical volume of the tank in m 3 Q = intake flow rate from the compressor in m 3 /min.2 = coefficient for large plants.6 = coefficient for small plants ACCESORIES AND SPARE PARTS TECHNICAL SUPPORT 279

THERMAL STRATIFICATION Thermal stratification is a physical process in which an hot fluid naturally tends to position itself higher than the cold one. The fluid (water) is always moving, and tends to remix, therefore the natural process of stratification must be supported to maintain an increasing temperature gradient from bottom to upper part and avoid the mixing of liquid at different temperatures. To allow stratification into the tanks means to create a remarkable difference in temperature storaging volume from upper to lower part. With important positive effects in terms of efficiency. A proper stratificated storaging means to have quantities of hot water available in short time. Example of stratification: Heat received during the day is accumulated in the higher part of the tank, reaching a suitable temperature for end user, while in the lower part temperature remains cold and even when solar collectors have a temperature below the one needed (afternoon-evening), the heat exchanger continues and tanks is storaging further energy. 75 C 7 C 65 C 6 C 55 C 5 C 45 C 4 C 35 C 3 C 25 C 2 C Heating delivery Standard Thermal stratification Efficient Thermal stratification 75 C 3 C THE TECHNICAL SOLUTIONS FOR THE OPTIMIZATION OF THERMAL STRATIFICATION LABYRINTH SPREADER (CORDIVARI PATENT) Performances are optimized thanks to the Labyrinth Spreader (Cordivari Patent). Its spread shape allows a perfect stratification of the water that returns back from the plate exchange to the tank. Heating installation efficiency is guaranteed. Sequence of thermographic images that show how Labyrinth Spreader works. EASY STRATIFICATION BUFFERS (Cordivari Patent) The heating return stratification system (Cordivari patent), avoid any turbolences, that would affect the thermal stratification inside the buffer tank. Thanks to this optimized solution, efficiency and energy savings are continuosly improved. Stratification plate Heating return stratificator system 1 2 3 4 5 6 Sequence of thermographic images that show how a system works with the easy stratification Buffer. NEW BUFFER CTS The new range of Buffer Tanks CTS are Cordivari s last innovative storage tanks designed for Solar Thermal Systems. The exclusive Stratification device CTS allows to have a prompt delivery of energy suitable for the production of hot water. The energy absorbed from the Solar Collectors is efficiently stratified in the upper part of the tank through the CTS stratification device and separation plate already assembled in Buffer CTS. The thermal stratification inside the Buffer tanks will be then improved naturally, without any external valves thanks to the mixed combination of: 1. Labyrinth Spreader that allows a perfect stratification of the water that returns back from user thanks to its spread shape avoiding mixes of temperatures of storaged water 2. Upper thermal loading systems that concentrates in the upper part of the tank hot water produced by the lower solar fixed coil in short time and high temperature. 3. Lower fixed Heat Exchanger designed for an optimal relation between space and efficiency. 298
