Heat recovery units series CFR-HE

The CFR-HE horizontal heat recovery units feature compact dimensions and easy assembly. The rotary heat exchanger is made from aluminium sheets, alternatevely plane and corrugated, one another wrapped. The result is a honey-comb structure in wich conducts pass both the fresh air and the stale air flows. The exchanger surface, made porous and hygroscopic by some treatments, allows to absorb the humidity. Half the rotor is immersed in the stale air flow which (in winter conditions) yields heat and humidity to the hygroscopic matrix; then, as a consequence of rotation,the fresh air flows in these conducts , recovering both heat and humidity (latent heat). The two fans are centrifugal type
