Flow balancing

From the wide range of recuperators on the market, DEFRO AIR units stand out, among others, with the FLOW BALANCING System. The system is crucial for reducing heating costs and, above all, maintaining constant and even air consumption. The airflow process is automatically balanced. It is worth noting that the FLOW BALANCING system is built-in without any additional charges.

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.

50 mm 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.

Enthalpy exchanger ERV*

The exchanger membrane is made of polymer, whose wall structure guarantees the recovery of thermal energy and moisture. *option additionally paid

Opening from two sides

Our ventilation units have inspection flaps on both sides of the recuperator. This gives us easier access to inspection activities. Possibility of rotating the control unit and universal installation.

Wall mounting console

Set includes - 2 pcs.
