22TECHNICAL 22 HEATING DATASHEET COMPACT SEMICONDUCTOR FAN HEATER CSF 028 | 250 W, 400 W >>Small, compact design >>Integrated pre-set thermostat >>Dynamic heating up >>Touch-safe >>Quick connection >>Clip or screw flange fixing 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 applications with high vibration.
