The Zehnder compact ventilation system for apartments lets you create a pleasant and healthy indoor climate in a comfortable and energy-efficient way. Designed for integration in a kitchen unit or niche in the wall, the system comprises the powerful Zehnder ComfoAir 180 ventilation unit and a specially developed compact air distribution system. Rooms are permanently supplied with fresh air, while used air is reliably extracted. You will never feel the need to open the window. This prevents heat loss and cuts heating costs. And thanks to humidity recovery via the optional enthalpy exchanger, indoor air will not get too dry in periods when the heating is on.
