Heat recovery units REK E

REK units with heat recovery are intended to improve indoor air quality with maximum energy conservation for air flows from 500 to 3000 m3/h. They provide ventilation and air conditioning of spaces (residential, business and industrial) via a plate recuperator, transferring heat from the return air to the fresh air. Heat is efficiently transferred from warm to cold air via an exchanger with a high heat recovery rate of up to 90% and low electricity consumption.

These compact units with on-board control are sound and thermally insulated with adjustable and replaceable plastic panels that allow easy service access to the internal elements of the unit from all sides. The construction is additionally reinforced with aluminum and corner profiles, and external installation is also possible with the addition of a plinth and a roof.

We offer 4 standard models: REK 5E, REK 10E, REK 15E and REK30E.

We adapt other models and requested performances to the user’s request.

The standard unit includes a high conductivity heat exchanger, EC fans, filters on the supply and exhaust air sides and a control unit for wall mounting.

Additional equipment includes an electric, water or DX heat exchanger, a bypass blind, and others according to the needs of the user.
