The PTC heater has no electricity on the outside and is fully sealed with moisture-proof design, which is extremely safe. PTC is the abbreviation of Positive Temperature Coefficient, meaning a positive temperature coefficient, which generally refers to semiconductor materials or components with a large positive temperature coefficient. Usually we mentioned PTC refers to the positive temperature coefficient thermistor, referred to as PTC thermistor. PTC thermistor is a typical temperature-sensitive semiconductor resistor. When it exceeds a certain temperature (Curie temperature), its resistance value increases stepwise with the increase of temperature.



1. Compared with the traditional heating element, the PTC heater has the following advantages. PTC heating element has the characteristics of automatic constant temperature. It does not require a temperature control system. The PTC heating element is used to heat the cold air. When the air is not supplied, the PTC heating element will not be damaged. Use PTC internal characteristics to control temperature, never over-temperature,
2. PTC heater When the PTC heating element is used to heat liquid (such as water), after the liquid is dried, the PTC heating element will not be damaged. It has long-term electrical and thermal stability. Fire risk, no open flame, no oxygen consumption, gentle wind, not boring, safe and warm
Long service life under normal environment
3. PTC heaters and the heating elements used on the market have the following advantages. The heater is not electrified and safe to use. The heating sheet is equipped with a fully-sealed moisture-proof design. Non-contact thermal resistance, higher efficiency. The surface is beautiful and novel. Under the same air outlet area, the power can be greater to meet the market demand in cold regions.
4. PTC heaters are not sensitive to voltage fluctuations and have a wide operating voltage range
5. The PTC heater device is convenient and elegant.
typical application:
1. Air heating, heater, air conditioning
