Principle of operation
The system is prepared for long-term use at room temperature of air within + 5ºС to + 35ºС and outdoor temperature from -25ºС (-30ºС after switching on the mini heater function) to + 45ºС.
The noise level at a distance of 3 meters from the device with the maximum operating mode of the recuperator does not exceed 38 dB. In the night mode - 25 dB.
The basic principle of a technical solution is the operation of a copper heat exchanger with a continuous thermal cycle that allows the formation of two opposite air streams within one cylinder.
Thanks to two fans, heat recovery is constant.
