Comfortable Indoor Ventilation

Your benefits from comfortable indoor ventilation

Fresh air 24/7

Zehnder's ventilation technology automatically ensures that only fresh, clean air enters apartments. Disturbances caused by open windows, such as street noise or annoying flies and other insects, are eliminated. 

More well-being and health

Ventilation technology removes not only stale air, but also pollutants emitted from furnishings. The decrease of excess humidity reduces the risk of mould on walls and furniture. 

Good for the wallet

The heat exchanger in the ventilation unit extracts the residual heat from the stale air and uses it to heat the fresh air from outside, which saves a lot of energy and money during the heating season. 

How does comfortable indoor ventilation work?

A comfortable indoor climate is usually associated with a balance between the right temperature, rapid removal of odours, the right humidity, and the prevention of draughts. But how does it work? Find out in our explanatory video.

Central ventilation with heat recovery

The central units ventilate the entire house and, via the air distribution system, air is supplied and discharged in the right place. The heat or cold that is already present in the house is recovered. This way, no energy is lost.

FAQ

Comfortable indoor ventilation systems ensure sufficient and healthy air exchange independently and around the clock. Far too often, however, newly built or modernised building envelopes no longer allow natural air exchange through cracks and joints. Sufficient, repeated purge ventilation in all rooms is not feasible for most people in everyday life. Particularly in large cities, opening windows also means fine dust, pollution or exhaust fumes. 

This is where Zehnder ventilation systems come into play. They transport clean, fresh air indoors – without any annoying pollen or impurities. In addition, excess humidity in the rooms, and thus the formation of mould, is prevented, which protects not only the health of the occupants but also the value of the property. 

You can open the windows at any time. However, this is not necessary for ventilation. A comfortable indoor ventilation system automatically ensures fresh air and optimal indoor air quality at any time of day and all year round. 

On the contrary: compared to window ventilation, with Zehnder comfortable indoor ventilation, the energy effect of the airtight building envelope is fully utilised. With up to 96% heat recovery, up to 50% heating energy can be saved.
