Ring Heaters

A cartridge heater is a cylindrical tubular heating device that can be used to provide precise heating for a variety of materials, machinery, and equipment. A cartridge heater, unlike an immersion heater, is fitted into a hole in the item to be heated and provides internal radiant heat. Cartridge heaters are often used to heat a metal block from the inside, and they can be custom produced to a precise watt density based on the application's needs.

How does a cartridge heater work?
Manufacturers of cartridge heaters empathize that the construction and functions of these heaters are very simple. The construction of a cartridge heater begins with a ceramic core with a resistance wire wrapped around it. The core and resistance wire are encased in a dielectric metal sheath made of steel or stainless steel. Heat is transferred from the resistance wire to the sheath and on to the material to be heated. It's a rather simple procedure. The coil inside the cartridge heater is heated by an alternating current, which heats the resistive wire. Through the mechanism of conduction, heat energy is transported from the wire to the metal sheath and then to the surrounding region. Cartridge heaters are the most efficient means to transfer heat into a metal solid because all heat energy is transferred from the element its surroundings.

Application of Cartridge Heaters
Cartridge heaters are most frequently used for heating dies, platens, molds, and other metal parts by insertion into drilled holes. They can also be used in liquid immersion applications. Below are some examples of specific applications:

  • Heating gases and liquids
  • Hot runner molds
  • Hot stamping
  • Laminating presses
  • Medical equipment
  • Semi-conductor
  • Plastic molding
  • Scientific equipment

Types of cartridge heaters

  • Thermocouple Cartridge Heaters
  • Flanged Cartridge Heaters
  • Swaged Cartridge Heaters
  • Miniature Cartridge Heaters
  • Multizone Cartridge Heaters
  • Square Cartridge Heaters
  • Split Sheath Cartridge Heaters
  • High Density Cartridge Heaters

How to install a Cartridge Heater?
Cartridge heaters are available in three-watt densities: low, medium, and high. They can tolerate operating temperatures of up to 1400 degrees Fahrenheit. The ideal working temperature will, however, be determined by the application for which the cartridge heater is being used. Installing a cartridge heater incorrectly can result in a variety of problems, including premature heating element failure. So, take your time and make sure you get it correctly. It's critical to choose the suitable cartridge heater for the job and double-check that the hole you're drilling is the right size for the heater. When using heat transfer lubricants, be cautious and protect the leads as much as possible. Our online manual contains detailed instructions on how to install a cartridge heater.
