At a glance
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.

Casing
The robust design prevents rotor movements that can cause leaks.
Suitable casing is available for each rotor size in the range. It can also be custom-made for the room ventilation unit in question on request. The standard casing is intended for vertical installation. However, smaller models can also be made for horizontal installation. Delivery in multiple parts for easier transportation is possible.Storage mass
