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)

Insulation kit incl. one set of infor-

sate. 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.
The profi-air defroster heating DN 125
consists of a galvanised steel-plate
housing with an integrated heating spi-
ral. With the help of the insulation kit
included with the delivery, thermal insu-
lation of the defroster heating is provid-
ed in order to prevent condensate
development. To insure protection
against overheating, a safety tempera-
ture monitor (with an automatic reset
function) and a safety temperature limit-
er (with a manual reset function) are
integrated into the terminal box of the
defroster heating.
This control ensures that the defroster
heating only operates if there is a risk
that the cross-flow heat exchanger can
freeze.
