Industrial Cartridge Heating Element / Electric Heaters
Product Description
1. Cartridge Heater Working Principle
Electric cartridge heater, also known as single-end tubular heater, one end can heat, another end is cold end.
It is made of a metal tube put into the resistance alloy wire as the heating materials, the alloy wire is filled with good insulation high purity magnesium oxide as filler, the product has a big power, high thermal efficiency, fast heat dissipation characteristics.
2. Cartridge Heater Characteristics
1>.
USA imported MgO, it can ensure the heating uniformity
2>.
Japan resistance wire, good heating performance.
3>.Alloy sheath for high corrosion resistance.

7. Cartridge Heater Application
| |
| Water Heating |
We recommend 10 watts per square centimetre when cartridges are to be immersed in water because the water removes the energy from the element very effectively. Commonly used as a chemical solutions heater. |
| Oil Heating |
Commonly used as engine sump heaters. When heating some oils, only 2 watts per square centimetre can be used otherwise the high cartridge heater surface temperature causes the oil to oxidise and carbon to be built-up on the surface of the heater. When this occurs, the carbon can thermally insulate the cartridge heater, causing the unit to heat up internally, often resulting in electrical failure. |
| Air Heating |
Elements of approximately 1 watt per square centimetre are suitable for convection air heating, eg. Anti-condensation heaters. |
| Die Heating |
Manifolds, hot runners and torpedoes.
Packaging
Hot melt glue applicators. |
