Cartridge heaters

High Performance Heating for Industrial Applications

Cartridge heaters

Cartridge heaters are compact, high-watt density heating elements designed to deliver precise, reliable heat in limited spaces. Ideal for a wide range of industrial and commercial applications, our cartridge heaters offer exceptional durability, uniform heat distribution, and energy efficiency. Whether you're heating metal molds, dies, platens, or sealing bars, our cartridge heaters are engineered for performance and longevity.

What Are Cartridge Heaters?

 

Cartridge heaters are cylindrical heating elements inserted into drilled holes to heat metal blocks or tools directly. Constructed with a **resistance wire coil insulated by magnesium oxide and encased in a stainless steel sheath, these heaters provide fast and efficient thermal transfer.

With diameters ranging from **6mm to 25mm (or 1/4" to 1"), they are available in **low, medium, and high watt densities to match the thermal demands of your specific process.

Specifications

  • Voltage: 12V to 480V

  • Wattage: Up to 100W/in² (15.5W/cm²)

  • Diameter: 6mm to 25mm or custom sizes

  • Sheath Material: Stainless Steel 304 / Incoloy 800 (optional)

  • Temperature Range: Up to 800°C (1470°F)

  • Lead Wire Options: Fiberglass insulated, PTFE, stainless braid, or armored

Key Features 

 

  • High Watt Density: Delivers rapid heating with minimal energy loss.

  • Precise Temperature Control: Maintains stable and uniform heat output.

  • Robust Construction: Stainless steel sheath resists corrosion and ensures long service life.

  • Customizable: Available in various lengths, diameters, wattages, voltages, and lead wire configurations.

  • Fast Heat-Up Time: Ideal for processes that require quick thermal response.

  • Optional Built-in Thermocouples for accurate temperature feedback.
