High Power Density Cartridge Heater with Stainless Steel Mounting
Flange
1. Description:
Cartridge heater is tube-shaped, heavy-duty, industrial joule
heating element (electrical resistance) used in the process heating
industry, usually custom manufactured to a specific watt density,
based on its intended application. Highly compacted they reach a
surface watt density of up to 25 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.
