Semiconductor Fan Heater CR 027

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

Semiconductor fan heaters prevent the formation of condensation and ensure an even temperature in switch and control equipment. The built-in regulator is used to set the desired temperature.
