Features 1、The PTC heater consists of selected high‑quality PTC thermal ceramic heating components as the heating source, and is composed of corrugated aluminum strips that are glued, welded and molded at high temperature. 2、Use national standard high‑temperature resistant insulation bracket, the spacing of the bracket screw holes is convenient for assemble and apply. 3、The over‑temperature insurance terminal is firmly connected without falling off or loosening, terminal silicone sheath with good high temperature resistance, corrosion resistance and strong flame retardant properties. 4、The wires are led out with high temperature resistant (300°) PTFE braid wires, and the terminals are installed firmly, ensure the wire harnesses are in good condition to avoid falling off and leakage risks. 5、PTC heater has the advantages of constant temperature heating, no flame (no redness), high heat conversion rate, minimal influence on the power supply voltage, long natural life. 6、When the heating reaches a certain temperature after power on, heating power will drop sharply and almost stop heating, when the heat dissipation temperature is low after a period of time, it will continue to generate heat to maintain the temperature.
