High-Temperature Cartridge Heaters
Precision Engineered for Demanding Applications
Our high-temperature cartridge heaters are designed for exceptional performance and longevity in the most challenging industrial environments. Featuring a high-purity magnesium oxide (MgO) core and a durable Incoloy® or Stainless Steel sheath, they provide rapid, uniform heat transfer up to 750°C (1400°F).
- High Operating Temperatures: Capable of reaching up to 750°C (1400°F).
- Superior Heat Transfer: Swaged construction for high thermal conductivity and dielectric strength.
- Durable Construction: Resistant to shock, vibration, and corrosion.
- Customizable: Available in various diameters, lengths, wattages, and lead configurations.

FAQ
Our high-temperature cartridge heaters are designed to operate continuously at temperatures up to 750°C (1400°F), depending on the application and sheath material selected.
Wattage selection depends on the mass of the material being heated, the required temperature rise, and heat losses. A proper heat calculation is recommended. Please contact our engineering team for assistance in determining the optimal watt density for your needs.
The most common causes of premature failure are contamination (from oil, moisture, etc.), an improper fit (too loose in the bore), and overpowering (incorrect watt density). Ensuring a clean, tight fit and correct wattage are crucial for long heater life.
Yes, but special considerations are required. In a vacuum, heat transfer is primarily through radiation and conduction, not convection. This often requires a lower watt density and specific design modifications. Consult with us for vacuum-rated applications.
