Fresh Air.

A constant supply of fresh air in the indoor spaces in which we spend more than 70% of our time is vital for our health. Zehnder Comfosystems comfort ventilation systems provide an assurance that equal amounts of stale and fresh air will be exchanged.

The comfort indoor ventilation system offers many advantages.


Discover the advantages

Healthy, energy-efficient and comfortable

The comfortable indoor ventilation system with up to 95% heat recovery provides energy-optimised air exchange, which can be automatically controlled to suit individual requirements. The system components, intelligently designed to work together, provide a constant supply of fresh air while extracting stale air.
