Cartridge Heaters

A cartridge heater is a heavy-duty industrial metal tube-shaped device with an electric heating coil enclosed, usually custom manufactured to a specific watt density, based on its intended application. These types of heaters are typically manufactured as low watt density, medium watt density or high watt density models. Each model offers a different approach to heating and covers different heat applications. The primary use of cartridge heaters is in the following industries: manufacturing, automotive, laboratory, or food equipment.

Low Watt Density Cartridge Heaters provide localized heating in processes requiring close temperature control such as:

  • Packaging and Labeling Machines
  • Hot Stamping
  • Plastic Injection
  • Glue Guns
  • Wax Pots
  • Other low temperature applications

Medium Watt Density Cartridge Heaters are a value alternative to High Watt Density Heaters. They are the optimal choice for a high temperature that do not require an integrated thermocouple, precise wattage distribution, are less than 65 watts per square inch on the heater sheath, and have lengths greater than 7 inches. They are used for:

  • Heating of Manifolds
  • Heating of Dies
  • Heating of Platens
  • Packaging Machines
  • Injection Molding Machine
  • Extrusion Machines

High Watt Density Cartridge Heaters provide excellent heat transfer efficiency, high operating temperature and long life and they are used for:

  • Heating for Press Tools
  • Thermo-Sealing in the Food Industry
  • Heat Printing
  • Heating of an Engine
  • Heating of a Braking System
