Touch-Safe PTC Fan Heater
CS 028 / CSL 028| 150 - 400 W

  • Compact size
  • Quiet operation
  • Heating power adjusts to ambient temperature
  • DIN rail or screw mount available

The CS 028 / CSL 028 fan heaters prevent formation of condensation and provide an evenly distributed interior air temperature in enclosures. The heaters are connected using the internal terminal connectors. The surface temperatures on the accessible side surfaces of the housing are minimized as a result of the heater design. The small size of the CS 028 / CSL 028 heaters make them ideal for use in enclosures where space is at a premium.

Accessory Part for Fan Heater CSL 028



Air guide for improved heat distribution

The air guide is an accessory part for use with the fan heater CSL 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 68 °F/20 °C (measured approx. 3.9”/100 mm above protective grille) and may make the use of custom heat ducts obsolete.
