Main features:
- central roof fan for the entire building and decentralized ventilation units for each apartment
- exhaust ventilation
- heat recovery
- suitable for renovations and new buildings up to 5 floors
Basic system components:
- central roof fan
- electrically controlled extract air valves
- decentralized ventilation units with heat recovery
In this exhaust system with heat recovery, contaminated air is extracted from the sanitary facilities of the apartments through a shared ductwork system connected to a central roof fan. Fresh air is supplied by decentralized ventilation units installed in individual apartments, where heat recovery takes place via a heat exchanger. This ensures a continuous supply of thermally treated fresh air to the interior. Compared to conventional exhaust ventilation systems, this solution provides higher user comfort and helps reduce the building’s energy consumption.
