Designed to improve indoor air quality, the latest ComfoAir Q units from Zehnder feature a diamond shaped heat exchanger to maximise heat transfer and deliver up to 96% heat recovery. Intelligent temperature control further enhances energy efficiency, while a pre-heater constantly adapts its operation in response to air temperature, air flow and humidity.
ComfoAir Q is described as a universal product that can be used for many types of properties and layouts. There are three models in the range – Q350, Q450 and Q600 – all certified as official Passive House Components by the Passivhaus Institute, making them suitable for use in highly insulated eco homes.
Optional CO2 sensors constantly measure air quality so that the unit delivers a constant balance of supply air and extract air volumes. The supply air volume is adjusted to the air quality in individual rooms.
For ease of installation and to reduce time on site, right and left handling is achieved through one single unit. The filters and pre-heater can be simply swapped over to change the configuration.
An innovative commissioning wizard ensures correct set-up at installation. A ‘dial a duty’ feature enables the installer to set the required air flow rate on site and the unit then automatically sets the optimal running speed.
