Combined circulation system and exhaust gas heat exchanger for energy recovery are executed onto customer requirement.
Combined circulation systems are mostly used for heat recovery between the supply- and exhaust air flows in air conditioning systems. At low temperature level and clean air flow, heat exchanger with copper tubes and aluminum fins are preferably used. For higher or aggressive ingredients alloyed steels or different grades of stainless steel are available.
Exhaust gas heat exchanger depending on the temperature range and application of unalloyed, low alloyed or used austenitic steels. If necessary, the exhaust gas heat exchanger can be equipped with housing, bypass unit, servo motors and transition hoods.
