Cartridge Heaters

Elmec Cartridge heaters are available in low, medium and high watt densities with internally externally connected leads. Cartridge heaters can be considered “component heaters” that are used to generate heat in many different applications. We also manufacture Split type cartridge heaters for high temperature applications. We built every technically possible heater as per your requirement. Elmec Cartridge Heaters uniforms heat distribution around & over the length of elements is obtained with a carefully positioned resistor wire of refractory material.

Frequently Asked Questions

Cartridge heaters are cylindrical, heavy-duty heating elements designed for insertion into drilled holes, providing precise and localized heat.

A cartridge heater generates heat by passing electrical current through a resistance wire wound around a ceramic or MgO core, which is then encased in a metal sheath. The heat is transferred from the sheath to the surrounding metal or material, ensuring efficient and uniform heating.
Cartridge heaters are efficient, versatile, and offer precise temperature control for various industrial processes.
Uniform heat distribution is accomplished through careful positioning of the resistance wire along the length of the heater, combined with high-quality refractory insulation to ensure even temperature across the element.
Typical applications include heating molds and dies, packaging machinery, sealing bars, food processing equipment, medical devices, laboratory instruments, and aerospace testing equipment.

High watt density cartridge heaters are ideal for applications requiring rapid heat-up and high operating temperatures, such as plastic injection molds, metal dies, and industrial sealing equipment.
