Electric Insulated Industrial and Domestic PTC Ceramic Heater Air Heating Element
Product description
This type of PTC heater has the advantages of small thermal resistance and high heat exchange efficiency. It is an automatic constant temperature and power saving electric heater.
PTC heating element products use u-shaped corrugated fins to improve its heat dissipation rate, and integrate the advantages of adhesive and mechanical, and fully take into account the various thermal and electrical phenomena of the PTC heating element during work, its combination Strong force, excellent heat conduction and heat dissipation performance, high efficiency, safety and reliability.
One of its outstanding features lies in its safety performance, that is, when the fan fails to stop, the power of the PTC heater will automatically drop sharply because it cannot get sufficient heat dissipation. At this time, the surface temperature of the heater is maintained at about the Curie temperature ( Generally around 250 ℃), so as not to cause "redness" on the surface of electric heaters.
PTC heating film is a new kind heater in the market .It is fixed by a pair of metal electrodes with leads on both sides of PTC element.
Metal electrodes having assembled a pair of belt fuse in two flanks side of average PTC Component, Yellow insulative film, Structure are still simple in the metal electrode outward appearance on envelop
The simple-structure heater gives out constant-temperature heat and does not need any additional temperature applications.

Applications
This product is mainly used for the electric heating of the ash bucket wall of the electric precipitator in thermal power plants to ensure that the dust in the ash bucket does not dew and ensure the smooth flow of ash.
It is also used for heating equipment such as scraper conveyors, ash silos, ash conveyers, conveying chutes, and lime powder silos.
