Product Description

  heater rod bundle electric heating element cartridge heater Applications: 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.

Highly compacted they reach a surface watt density of up to 30 w/cm².  It may be used to heat any kind of substance or material, such as oil, air, or sugar. However, a common application is plastic pellets, which are melted in order to form molded plastic parts. An example of such a process is the "hot runner" process. Cartridge heaters resemble tubular heaters structurally but tend to have higher watt densities.
