Heat recovery Why recover heat? The question should in fact be: Why not recover heat? Amazingly, 100 percent of the (electrical) energy input to a compressor is converted into heat. Up to 96 % of this energy can be recovered and reused for space heating or hot water production purposes. This not only reduces primary energy consumption, but also significantly improves the total energy balance. Saves money and benefits the environment For plate heat exchanger systems Compressor model Rated power Heat recovery Annual savings potential with fuel oil Heat in the compressor Amazingly, almost 100 percent...

Heat recovery Minimise primary energy consumption for heating The enclosed, compact design of modern rotary screw compressors makes them especially suitable for heat recovery. Direct use of the recyclable heat via a ducting system enables up to 96 % of the compressor’s total energy requirement to be recovered and used for heating purposes. This is the case irrespective of whether fluid-injection cooled compressors or dry-running screw compressors are used. energy reusable for heating purposes Heat recovery a win Amazingly, 100 percent of the electrical drive energy input to a compressor is converted...

Heat recovery Minimise primary energy consumption for warming process, heating and service water Using recyclable heat from the compressor, heat exchanger systems can provide on-demand heating and service water warmed to temperatures up to 70°C, or even 90°C, depending on requirement. Conventional warming of heating and service water using recyclable heat is performed by PTG plate heat exchanger systems. Special fail-safe heat exchangers are recommended for applications that have no other interconnecting water circuits and where it is essential that the water being warmed remains uncontaminated,...

Equipment Hot air heat recovery PTG plate heat exchanger Tube-type heat exchanger All KAESER rotary screw compressors can be fitted with exhaust ducting. The ducting is installed on-site. Neighbouring rooms and warehouse space, for example, can be heated with the warmed cooling air. Rotary screw compressors from the SM series (from 5.5 kW) upwards can be equipped with PTG systems. Depending on the available water quality, either integrated plate or tube-type heat exchangers can be used in watercooled systems. Our compressed air specialists can advise you regarding which design is right for your...
