Cartridge heaters are an excellent choice to use as a conductive source for heating solid metal plates, blocks and dies or as a convective heat source for use in a variety of liquids and gases. Cartridge heaters can be used in a vacuum atmosphere with proper design guidelines. The Cartridge heaters with Flange used on heating in immersion liquids we call it flange immersion cartridge heater.
The Flange Immersion Cartridge Heater Mainly used in the below situations:
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.
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.
Elements of approximately 1 watt per square centimetre are suitable for convection air heating, eg. Anti-condensation heaters.
Manifolds, hot runners and torpedoes.
