Combi 302 Polar

Product Description

Combi 302 Polar combines passive and active heat recovery in one single unit. Combi 302 Polar recovers 85-90 % of the extracted air via the counter flow heat exchanger and the excess energy is recovered by the built-in heat pump.
The combination of passive and active heat recovery obviate a heating element, because the heat pump is able to increase the supply air temperature significantly.
Combi 302 Polar is also able to cool the supply air and reduce the relative humidity, thus making the supply air feel much colder.

Combi 302 Polar comprises the following:

•  Counterflow heat exchanger for passive heat recovery.

• 100% automatic bypass for free cooling

•  Heat pump for active heat recovery for fresh air heating.  COP > 4.

•  Summer cooling function for the fresh air = Reversible heat pump.

•  Two low-energy EC fans.

• Built-in electrical heating element (frost protection).
