COMPACT SEMICONDUCTOR FAN HEATER
CSF 028 | 250 W, 400 W
The compact fan heater prevents formation of condensation and provides an evenly distributed interior air
temperature in enclosures with electric/electronic components. The touch-safe plastic housing and the small
dimensions makes it ideal for use in enclosures with high packing density. The CSF 028 is equipped with a preset
thermostat. It is connected via external clamps. The fan heater is available with two different
mounting systems
– either mounting by screw flange or by clip. The robust screw flange fixing is particularly suitable for appli
cations
with high vibration.

Example of connection
Fan heater CSF 028
Air duct for improved heat distribution
The air duct is an accessory part for use with the fan heater CSF 028.
It can easily be clipped onto the protective grille of the fan heater
without use of any tools, and diverts the exiting warm air by 45°. This
results in an overall improved heat distribution within an enclosure or
cabinet. The temperature above the protective grille is reduced by up
to 20 °C (measured 100 mm above protective grille) and may make
the use of a heat conduction plate obsolete.
