Semiconductor Fan Heater CR 027
Yueqing Ann Electric Co., Ltd. [China] 
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.
