Product Description


  • Low surface temperature
  • Integrated thermostat
  • Compact size
  • Wide voltage range
  • Double insulated protection
  • DIN rail mountable

The CSF 028 fan heater prevents formation of condensation and provides evenly distributed interior air temperature in enclosures. The touch-safe plastic housing and the small size makes it ideal for use in enclosures with a high packing density. The heater is equipped with a fixed set point thermostat and is easily wired via external pressure clamps. Two different mounting options are available – DIN rail or screw tabs. The robust screw tab mounting is particularly suitable for applications with high vibration.
