Brief Introduction On the Safety performance of PTC heating elements

Some customers asked us what is the festures and advantage for the PTC heating elements. they dont understand why the cost of  PTC heating elements are relatively higher than the noral tubular heating elements. Today we are going to talk about the safety performance of the PTC heating elements.


PTC heating element is composed of PTC ceramic heating element and aluminum tube: galvanized outer pressure plate, stainless steel corrugated spring sheet, galvanized inner pressure plate, single-layer aluminum heat sink, PTC heating sheet, double-layer aluminum heat sink, nickel-plated copper electrode terminal And PPS high temperature plastic electrode sheath.

The PTC heating element has the advantages of low thermal resistance and high heat exchange efficiency. It is an electric heater with automatic constant temperature and power saving. The outstanding feature lies in the safety performance. Under any application, the phenomenon of "redness" on the surface of electric heating tube heaters will not occur, When the PTC heating element stops in case of fan failure, the power of the PTC heater will automatically drop sharply due to insufficient heat dissipation. At this time, the surface temperature of the heater is maintained at about the Curie temperature (usually around 250 ℃), so as not to Produce the phenomenon of "redness" on the surface of heaters like the normal electric tubular heating elements.
