This area is characterised with a rather cold climate with summer temperature averaging 9-10 °C. The frost already sets in October and may last till May while temperatures may drop to -50 °C.
The project required a ventilation unit capable of keeping the building warm and providing a reliable supply of fresh air.
This is exactly why the client chose BlauAIR 07 CFH 6000-W. This air handling unit has a bypass duct with an automatic actuator. When the automatic control system detects near-freezing conditions, the exhaust fan is automatically disabled while the supply fan continues to deliver warm indoor air to temper the heat exchanger core.
As soon as temperature balance is restored, the air handling unit reverts to normal operation. To ensure successful operation in challenging climatic conditions, the BlauAIR unit was fitted with heaters to prevent core freezing and provide additional supply air heating.
