8.2 Description of Components
Fans
The fans have external rotor motors of EC type which can be steplessly controlled individually between 10–100%. The motor
bearings are life time lubricated and maintenance free. It is possible to easily disconnect and replace the fans if necessary.
Filters
The filters are of filter quality G4 for both the supply air and extract air filter. The filters need to be cleaned regularly (and replaced
when polluted) during maintenance. New sets of filters can be acquired from your installer or wholesaler.
Heat exchanger
The unit is equipped with a highly efficient, counter-flow plate heat exchanger. Supply air temperature is therefore normally
maintained without adding additional heat. The heat exchanger is removable for cleaning and maintenance during service.
Condensation drainage
Depending on the relative humidity in the extract air, condensation may occur on the cold surfaces of the heat exchanger, on one
side in winter time, on the other side in summer time (table 6.b).
The condensate water is led out through drainage pipe.
Thermistors
Temperature probes to implement temperature dependent functions.
