Pencil Heater Element

Jaye Heater Technology Co., Ltd. is one of the most reliable manufacturers and suppliers of pencil heater element in China, also supports custom service. Welcome to wholesale high quality pencil heater element at competitive price from our factory.

Pencil heater element has developed rapidly in recent years. It has been widely used in the industrial field and in the field of civil electrical appliances, and can be seen everywhere in people's daily life.

Long lasting

The heating wire uses nickel-chromium heat-resistant alloy, because it uses heat-resistant insulating magnesium oxide, it has a longer life than previous products.

Good thermal conductivity

The heating wire is separated from the shell by an insulator, which has good insulation and good thermal conductivity.

High mechanical strength

Multiple tubular heater can be used at the same time, and wiring can be coordinated and unobstructed.

Robust structure

The coil-shaped heating wire is set endlessly in the center of the reheating rod, and this part uses the porcelain magnesia made of high-precision magnesia firing.

Precautions for the use of Pencil heater element:

1. During the use of high-watt density pencil heater element, due to its rapid heating and poor heat dissipation conditions, the external stainless steel tube body of the electric heating is often burnt, oxidized, and deformed, which causes the internal heater-the electric heating  alloy wire to melt due to high temperature air burning. As a result, the life of it itself is shortened. Therefore, a good one not only requires good production quality, but also requires the material and processing aperture of the mold (the closer the hole diameter is to the pipe diameter, the better). Outside the tube, it also facilitates the heat transfer between the two, thus prolonging the service life of the tubular heater itself.

2. Pay attention to the precision of the deep hole processing of the mold, and do not drill at both ends, because the junction cannot be tightly closed and there are large pores, which makes it poorly radiate and the temperature of the heated body is uneven.

3. It should be noted that the magnesium oxide powder at the outlet end of the electric heating tube should not be infiltrated by pollutants and moisture in the place of use to prevent leakage. 5mm is reserved outside the mold.

4. Pencil heater element is used for starting up, and it can be preheated for 5 minutes to avoid the risk of electric leakage due to humid air or water seeping into the tube. It must be equipped with a grounding wire.
