Compact Multifunction system series with heating

The Compact Multifunction system series with heating. Compact P is an unconventional ventilation unit that, unlike other ventilation units, recovers 100% of the heat in the exhaust air. Via the counterflow exchanger, up to 95% of the energy in the exhaust air is recovered for heating the outside air. The remaining energy is used by the built-in heat pump to produce the hot domestic water.
