PTC (Positive Temperature Coefficient) air heaters are advanced electric heating devices built around PTC thermistor technology. Unlike traditional resistive heaters, their resistance increases exponentially with temperature, enabling self-regulating heat output that eliminates overheating risks.

The PTC insulated heater is a safe heating device that combines high-performance ceramic insulation material with a PTC (positive temperature coefficient) heating element. Its core feature is a double-insulated structure that completely isolates the heater from the external environment, effectively preventing the risk of leakage and complying with stringent electrical safety standards. The heater utilizes a self-regulating PTC chip, eliminating the need for an additional thermostat. It automatically reduces power as the temperature rises to avoid overheating. With its advantages of high-voltage resistance, breakdown resistance, high thermal efficiency, and long life, it is widely used in safe heating applications for medical equipment, household appliances, new energy vehicle battery packs, and industrial precision instruments. It is particularly irreplaceable in areas requiring strict insulation protection.
