The compact fan heater prevents formation of condensation and provides an evenly distributed interior air temperature in enclosures with 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 applications with high vibration.
