Products Recuperators

The recuperator manufactured by FON ENGINEERING can be used to achieve energy efficient space ventilation. The heat energy which is saved with the use of a recuperator is around 50% of the energy needed to heat a room.

The recuperator is a device which in addition to two ventilators also contains a heat exchanger. The polluted air gives off a part of its heat energy to the fresh air being injected into the room. The device is compact and only takes up a little space so that it can even be installed on the ceiling. The walls of the device are made of isolated panels, 25 mm thick. It is possible to install a recuperator both in a vertical and horizontal position. Filter maintenance and cleaning are simple procedures. It is possible to install various other additional elements and equipment such as: blinds, a circular adapter, a water or electric heater, an external heating unit and a control table which can regulate speed.


For the ventilation of offices, hotels, restaurants, theaters, homes and the like.

Basic work principle:

The installation of a recuperator into the ventilation systems saves a significant amount of energy needed to heat or cool air.
