KPI Series E and HIndoor unit - enthalpy recovery system

System Free Ventilation

With the KPI cross flow heat recovery units it is possible - depending on the type of exchange pack - to perform enthalpic heat recovery (Series E) or of sensible heat recovery only (series H).This lets you reduce the power requirements of air conditioning systems where continuous ambient air renewal is required.Moreover, thanks to the new internal geometrical layout, which supports linear flow between ambient air intake and extraction ducts, installation in the field is easier and above all does not feature the typical duct crossing issues of standard models.KPI heat recovery units assure the environment has fresh, clean and pleasant air

using the combined control with the SYSTEM FREE conditioning system.
