Rotory heat exchanger Viskan

The Viskan rotary heat exchanger is recommended for ventilation systems without mechanical cooling. The condensation rotor only transfers humidity during the winter when extract air condenses in the storage mass and is taken up by the supply air stream. Untreated aluminium foil is used for heat recovery.

Hoval energy recovery systems are independently tested time and time again (for example, at the building technology testing laboratory of the University of Lucerne). All technical data is based on these measurements. This means that this is reliable data for planners, installers and operators. You ...
