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.
