1) PTC(PTC heater) , the heating element is also called a PTC heater, and is composed of a PTC ceramic heating element and an aluminum tube. This type of PTC heating element has the advantages of small thermal resistance and high heat exchange efficiency, and is an automatic constant temperature and power saving electric heater. The outstanding feature is the safety performance. Under any application, the surface of the electric heating tube heater will not be reddened, which may cause burns, fires and other safety hazards.
2) MCH(Metal Ceramic Heater), the ceramic heating element is made by sintering the electric heating body and the ceramic at a high temperature, and the ceramic heating element is a new type of high-efficiency environmentally-friendly and energy-saving ceramic heating element, which is heated and returned quickly.
