Characteristics:
1) PTC heater which consists of PTC elements and radiator is a temperature holding automatically heater. about its safe feature, PTC heater's surface temperature is Curie temperature while there is no wind
2) Temperature rises rapidly. It can control temperature automatically while there is no wind and has low ageing
3) It can be designed among 12-380V
4) Power and shape can be designed conveniently
5) Safety and reliability
