Centralized ventilation unit COMBI S 302 POLAR TOP

Combi S 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 83% 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 S 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 S 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. DBTU damper If there is not enough space to fit an EM-box, Nilan offers a DTBU damper, which can be fitted between kitchen and bathroom. The damper functions precisely like the EM-box but requires longer cables. 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. The APP allows you to adjust the default settings of, for instance, room temperature, fan speed level and the humidity control system.
