Innovative Modulating Summer By Pass

During summer nights and in the transition periods with strong sunshine, the house often becomes too warm, while the outside air remains pleasantly cool. In this case heat removal by what is known as free cooling helps: The cooler outside air is fed to the rooms in the living area, bypassing the heat exchanger.

The Zehnder ComfoAir ventilation unit is equipped with an automatic bypass for just this purpose. The bypass is a standard component and takes 100% of the extract air past the heat exchanger. The personal comfort temperature is adjustable.

The modulating summer by-pass is guided by an optimum comfort temperature for the home utilising temperature, humidity and an intelligent algorithm to look at both internal and external conditions to provide the optimal temperature.

Innovative Air Volume Balancing

New and patented: innovative sensor technology automatically ensures balanced supply air and extract air volumes. This flow control  guarantees maximum heat recovery. What’s more, you save time during commissioning because of the unit’s dial-a-duty feature where the required air flow is input and the unit will automatically adjust the motors to achieve this.

Ideal control

The Zehnder ComfoAir Q models can be controlled with a wide variety of tools. Anything is possible: from a simple display on the unit, to an app* that can be used on the go, right through to fully automated, demand-based ventilation using sensors.

*App based control available with add on of LAN-C or LAN-Pro module.

Simply unbelievable efficiency

Zehnder ComfoAir Q Heat Recovery units offer an outstanding and world class 96% heat recovery efficiency and SFP as low as 0.53 (Q450 model) as a result of a design that maximizes heat transfer and helps overcome air resistance.

At every point Zehnder ComfoAir Q is the best choice- for SAP, for energy performance, for indoor air quality and importantly for the homeowner. Find out more about the technology that is driving this excellent performance and which also contributes to an easier commissioning process.
