Air-to-air-heat-exchanger improved Air-to-air-heat-exchanger improved
On the first sight, this air to air heat exhanger looks different. Many other vendors just purchase heat exchangers and built an own unit out of it.


Humidity recovery from waste air Humidity recovery from waste air
Unitl now, humidity recovery was only with rotating heat exchangers possible, This countercurrent heat exchanger is out of a material to recover also humidty.

Air exchange with ventilator from outside The ventilators are only in the air streams seperated by the heat exchanger from the living space. The heat exchanger beomes in this way also a silencer. Summer bypass flap In the lower part of the device the bypass flap. Some other vendors deliver this only as special accessory. But 2 to 3% of the air could go the wrong way. 60 squaremeter heat exchanger Not out of plates, but from channels exists this gegenstrom crosscurrent heat exchanger. The exchange surface is 3 times larger than in usual heat exchangers. Filter box for earth heat exchanger Below the air input is this filter box before the air continues to the long pipe below the earth, the earth to air heat exchanger. Pipes into cellar The unused pipe into cellar system is sealed with a cover. The special tool is put on to remove the cover from the empty pipe into cellar.
