These small heaters are designed to prevent condensation and to ensure a minimum operating temperature in small enclosures.

Fan heater prevents formation of condensation and provides an evenly distributed interior air temperature in enclosures with electric/electronic components. The heater is connected using the internal terminal connectors The small size of the CS/CSL 028 makes it ideal for use in enclosures where space is at a premium.
