Modulating pre-heater

Pre-heater for even greater control of the exchanger against freezing. AFC system – ANTI FREEZE CONTROL – working with a modulated heater.

100% Bypass

Only 100% bypass guarantees fresh and cool air in the summer.

Quiet operation

Our recuperators are among the quietest ventilation units available on the market. This is due, among other things, to the use of special EC radial fans dedicated to heat recovery.

Thermal and acoustic insulation

Thanks to the use of a thick layer of insulation, the air handling unit is protected against condensation of water vapor in the recuperator, and heat losses are virtually eliminated.

Mounting console

Suspended version for F recuperator (4 pcs.)
