EvoAir C Series

The Acetec EvoAir C-series offers ventilation units with counterflow heat exchangers instead of rotary heat exchangers.

In a counterflow heat exchanger, the fresh supply air and the warm exhaust air, which comes from areas like kitchens and wet rooms, are directed through separate channels. Through the walls of the heat exchanger, the warmth from the warmer exhaust air is transferred to the cooler supply air before it is introduced into the building. This results in a high heat recovery efficiency, often over 90%.

It is common to install units with counterflow heat exchangers in restaurants or stairwells with multiple apartments, as no unwanted air transfer occurs. This prevents the spread of, for example, cooking odors or cigarette smoke.
