Zehnder ComfoSpot 50 is a decentralised comfort ventilation unit, with heat and humidity recovery, using synchronous supply and extract air operation. It is often used in apartment renovations as well as in new residential builds. The comfort ventilation unit is suitable for venting individual rooms. An enthalpy exchanger, which ensures a high degree of heat and humidity recovery, is standard on the unit, which therefore provides a comfortable indoor climate, especially in winter.
