Zehnder ComfoUnit

The ventilation system’s supply and extract air are controlled by the Zehnder ComfoAir ventilation units. With the user-friendly control panel, the air volume can be simply adjusted to suit requirements. All units are fitted with a filter as standard; fine and pollen filters can be retrofitted.

Zehnder ComfoFresh

Zehnder ComfoFresh air distribution systems bring fresh air to all rooms and simultaneously remove stale, humid and contaminated air and odours. Displacement ventilation allows air to be exchanged without draughts and bothersome noises, at the highest possible efficiency. The air volume can be individually adjusted. Zehnder ComfoFresh comes in the OnFloor (on the unfinished floor) and InFloor (in the unfinished floor) installation models, or with a mixed installation option.

Zehnder ComfoFond-L

Energy efficiency can be guaranteed even in frosty weather with the Zehnder ComfoFond air ground source heat exchanger. The ground, with its relatively constant annual temperature, is utilised as a passive store. The warmer ground releases energy to the outside air and this tempered air flows into the ventilation unit. In summer, the ground is cooler than the outside temperature. Now the effect can be utilised in the opposite direction: The outside air is cooled before reaching the house.

Zehnder offers innovative, sustainable and smart solutions for a comfortable, healthy and energy-efficient indoor climate. 2017 has brought yet more innovations in the area of comfortable indoor ventilation.
