Upon request of an offer about heat and total energy recovery exchangers, customers should provide data such as supply and exhaust air flow (m3/h or kg/h), temperature (˚C) and humidity (%RH), desired energy (kW) or expected efficiency (%)from the system, allowable pressure drop of air (Pa), maximum dimensions for the exchanger (mm x mm x mm) etc.

To be able to compare the air-to-air heat recovery and total energy recovery exchanger properties and to pre-select the type of exchanger, please refer to sources such as ASHRAE Handbook (HVAC System and Equipment)
