Product description
Combi302 Polar is a ventilation unit that combines two heat recovery technologies.
Passive heat recovery takes place via a counterflow heat exchanger that utilises between 85% and 95% of the energy in the extracted air. Active heat recovery takes place via a heat pump that utilises the residual energy. The heat pump has a COP >4, which eliminates the need to install a heating coil with an attached mixing circuit. Combi302 Polar can increase the temperature of the supply air to over 30°C.
The heat pump also makes it possible to cool the supply air in the summer by up to 10°C.Due to the low air exchange, this does not function as an air conditioning system, but cooling the air intake reduces its humidity, giving a more pleasant and comfortable climate inside the home, even when the indoor temperature is high.
Combi302 Polar is delivered with a built-in pre-heating element, which protect the counterflow heat exchanger against icing. This ensures continuous operation at low outdoor temperatures.
