Why should I recommend Zehnder ComfoAir Q?

Zehnder ComfoAir Q is the best possible solution when it comes to energy efficiency and the well-being effect. The unit makes an important contribution to comfortable fresh air, is practically silent during operation and offers the right operating solution to suit every need – from the display via an app, right through to fully automated, demand-based ventilation by means of sensors.

With so many new features, has commissioning become more complicated?

No, because the Zehnder ComfoAir Q menu has an integrated commissioning wizard that helps you set up the ventilation system exactly as required in three steps. The fan speed is also controlled fully automatically by sensors, meaning you do not need to make any extra adjustments during commissioning.

What do I need to consider when planning?

Three units are available, each with a different air volume: 350, 450 and 600 m3/h. As a result, you can design a ventilation system to suit your project perfectly. Sudden changes to the original plans as far as connectors are concerned are no problem at all, because the Zehnder ComfoAir Q design incorporates the right-hand and left-hand version in the same unit.

Does this mean I will also be up-to-date with future energy saving requirements?

Zehnder ComfoAir Q has been awarded or applied for all the relevant energy efficiency certificates. In fact, the unit actually exceeds current European energy saving requirements. Classification into the best energy efficiency class (A+) speaks for itself (depending on the controller/sensor technology chosen). Zehnder ComfoAir Q is currently the market leader in its class, particularly when it comes to heat recovery. This means that the unit is the most future-proof solution that you can offer your customers.
