Small, compact design
Quiet operation
Heating power adjusts to ambient temperature
Din rail or screw mount available
The CLS 028 FAN HEATER prevents formation of condensation and provides and 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 CSL 028's small size make it ideal for use in enclosures where space is at a premium.
