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.

Features |
Benefits |
|
Nickel chromium resistance wire |
Assures even, efficient distribution of heat to the sheath |
|
Magnesium oxide insulation of specific grain |
Results in high dielectric strength and faster heat-up |
|
Incoloy® sheath |
Resists oxidation and corrosion from many chemicals, heat, and atmospheres |
|
Minimal spacing between element wire and sheath |
Results in lower internal temperature Accommodates a design with fewer or smaller heaters operating at higher watt densities |
|
Conductor pins |
Provides a metallurgical bond to the resistance wire Ensures a trouble-free electrical connection |
