The robust and durable DWA systems are mounted very quickly and easily via the serially equipped wall-mounting plate and create a significantly comfortable climate in buildings. Plants, employees or customers in sale rooms are protected from overcharged temperatures. For a fully automatic operation the standard version devices are either equipped with a step-switchable motor with 5-step switch and thermostat or alternatively with a stageless adjustable motor in 0-10 voltage controller with the Doll comfort system.

Both systems are working highly energy saving trough the use of efficient motor design and are reliable and free of maintenance.
