Design and operating logic
The warm, used exhaust air enters the ventilation system from
the room, is cleaned in the exhaust air filter and flows through
the heat exchanger. It is then led outdoors by the extract air
fan via the exhaust air pipe.
The fresh outside air flows into the ventilation system and is
cleaned in the supply air filter. The air then continues to flow
through the heat exchanger and is led into the room by the
supply air fan.
In the heat exchanger, the heat from the warm extract air is
transferred to the cold outside air. Here, the two air flows are
completely separated from each other. The heat recovery
minimises heat loss in the cold season and thus saves heating
costs.
