Centralized ventilation unit COMBI 302 POLAR TOP

heat-recoveryresidentialfor home

Combi 302 Polar Top 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. Combi 302 Polar Top 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. Combi 302 Polar Top 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. Electrical heating element incl. regulation When you fit an electrical heating element, you can raise the fresh air temperature to the desired level at any time. The electrical heating element is supplied ready to fit into the fresh air duct and, for easy fitting, the device is pre-fitted with all the required sensors (not for GEO / AIR). Gateway - APP solution By purchasing a Nilan gateway, the user can gain access to the unit via a Nilan User APP. The APP enables the user to access and monitor the current operation, also from the outside of the property.
