The profi-air defroster heating DN 125 / 900 W is an air pre-heating device which can be integrated into the fresh air pipe of ventilation
systems (profi-air 180 flat) and which is intended to protect the heat exchanger from freezing condensate. The defroster heating can be
switched on and off through the frost protection control incorporated in the ventilation device. To do so, the electric heater coil must
be connected to the profi-air 180 flat control.
This control ensures that the defroster heating only operates if there is a risk that the cross-flow heat exchanger can freeze.
The profi-air defroster heating DN 125 consists of a galvanised steel-plate housing with an integrated heating spiral. With the help
of the insulation kit included with the delivery, thermal insulation of the defroster heating is provided in order to prevent condensate
development. To insure protection against overheating, a safety temperature monitor (with an automatic reset function) and a safety
temperature limiter (with a manual reset function) are integrated into the terminal box of the defroster heating.
