Zehnder CA155WMe-GB ComfoAir 155 WMe Smart Heat Recovery Unit

Zehnder CA155WMe-GB ComfoAir 155 WMe Smart Heat Recovery Unit

The ComfoAir 155 WMe is a ventilation system designed to provide improved indoor air quality in dwellings. As a whole house system, the unit continuously extracts air from the non-habitable rooms and supplies fresh, filtered air to habitable rooms. Heat that is recovered from the air drawn from the bathrooms and kitchen is passed through a heat exchanger and the heat that is recovered is transferred, to temper the supply air in habitable rooms to provide a comfortable indoor environment.

A boost speed facility is provided to increase the ventilation rate, e.g. when cooking or showering, providing a comfortable indoor environment.

The Zehnder ComfoAir 155WMe is designed to enable better and easier specification of ventilation in new properties. It contains features such as its automatic true summer by-pass, high heat recovery efficiency and integrated humidity sensor to provide a comfortable, healthy and energy-efficient indoor climate.
