CFR-HERS heat recovery units are designed to meet both air renewal and heat&humidity comfort request by typically industrial and civil environments; this by limiting as much as possible the use of primary energy. Therefore, they are provided with a heat recovery system composed of a crossflow air-to-air heat exchanger, low consumption EC direct driven fans with electronic control and long-life filters for lower air pressure drop and high air quality level.

These units, equipped with the needed additional treatment optional systems, may be a stand-alone plant solution or can well integrate central heating/cooling systems, both series and parallel layout.

CFR-HERS series is composed of five sizes, double deck version only, to cover a needing of fresh air from 1500 up to 15000 m3/h.

The models of the series CFR-HERS can be given with a ionization system of the air called BIOXIGEN®.

This system, unique in his type, makes the air and surfsces of the machine, of the ducts and of the bordering rooms healthy and good smelling.
