Cartridge Heaters

Cartridge heaters, also known as rod heaters, are tube-shaped, heavy-duty heating elements used in the process heating industry, usually custom manufactured to a specific watt density, based on its intended application. Cartridge Heaters provide superior heat transfer with uniform temperature and resistance from oxidation and corrosion at high temperatures. Our popular Cartridge heaters are the following design styles: Straight, Right Angle, Flange, 90 Degree, Posts out Both Ends, Post on Same End, and Distributive Wattage.

These process heaters are primarily used in mold and fit snug inside a cavity and helps heat solids by reaching high temperatures. Cartridge heaters have the versatility of being able to carry thermocouple inside to help control temperatures of the heater more accurately. Various diameters allow for it to be used in any cavity and can be custom designed with any cold section.
