The cartridge heater is a tube-shaped, heavy-duty, industrial Joule heating element used in the process heating industry, usually custom manufactured to a specific watt density, based on its intended application. Compact designs are capable of reaching a watt density of up to 30W/cm².
Pencil heaters from Shenglong 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. Pencil heaters can be used in a vacuum atmosphere with proper design guidelines.
