Local ventilation unit with heat recovery based on the principle of varying direction of air flow
Unit body KORASMART TUBE is installed in a tube passing through the perimeter wall and connection the interior and exterior. Upon acitvation, the fan inside the unit turns from the interior to exterior, so the evacuated stale air charges the heat exchanger. Approximately after a minute, the direction of the rotation switches back and the cold supplied air takes the accumulated heat from the exchanger. This process then repeats continuously. The continuous suplly of fresh air requires two unis installed in the room, opposite each other. With only one unit the direction of air flow changes in regular intervals.
