Zehnder ventilation systems ensure a healthy indoor climate while being highly energy efficient. Our ventilation products not only enhance well-being, but also help to preserve property value.
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.
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.
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.
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.
Comfortable indoor climate can be achieved by good ventilation. Zehnder offers suitable solutions for every project situation:
Ventilation systems for individual rooms, single-family houses, multi-family buildings, and light commercial projects
Air distribution systems and ventilation units tailored to the size of the rooms or building and the desired comfort
Suitable products for new constructions or renovations
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.
