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 sales-rooms are protected from overcharged temperatures. For 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 outmost energy-saving by the use of efficient motor design, reliable and free of maintenance.

A quick, safe and more comfortable climate in the building !
