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 heater prevents formation of condensation and provides an evenly distributed interior air temperature in enclosures. The heater is 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 make it ideal for use in enclosures where space is at a premium.
