Industrial Cartridge Heaters for Precision Heating & Heavy-Duty Applications

One Cartridge Heater Platform. Three Proven Solutions.

Cartridge heaters are critical components in industrial heating where precision, reliability, and compact design are required. Whether you need maximum watt density, compensation for oversized bores, or controlled bolt expansion for heavy equipment assembly, our cartridge heater solutions are engineered to meet your exact operating conditions.

Why Choose Our Cartridge Heaters

• High Heat Transfer Efficiency - Optimized internal construction for fast, uniform heating
• Custom-Built to Specification - Diameter, length, wattage, voltage, and terminations tailored to your application
• Rugged Industrial Design - Built for vibration, high temperatures, and continuous-duty operation
• Wide Industry Compatibility - Plastics, packaging, power generation, heavy equipment, and more
• Precision Temperature Control - Optional built-in thermocouples, sensors, and controllers

High-Density Cartridge Heaters

Best for applications requiring maximum power in minimal space

High-density cartridge heaters are designed with resistance wire positioned close to the sheath and compacted MgO insulation to deliver superior heat transfer and watt densities up to 200 W/in².

Key Features:

• Extremely efficient heat transmission
• Tight diameter tolerances for optimal fit
• Available in dual-voltage and three-phase designs
• Optional features including thermocouples, graphite coating, moisture-resistant seals, and zoning
• Ideal for plastic molding, packaging equipment, food processing, medical devices, and semiconductors

Expandable Cartridge Heaters

Best for worn, oversized, or hard-to-service insertion holes

Expandable cartridge heaters solve heat transfer issues caused by oversized or worn bores. When energized, the two semi-circular legs expand outward, pressing firmly against the hole wall for improved thermal contact.

Key Features:

• Compensates for oversized or out-of-tolerance holes
• Improved heat transfer compared to loose-fit cartridges
• Reduces premature heater failure
• Available in multiple diameters, lengths, voltages, and wattages
• Ideal for molds, dies, platens, hot stamping, and plastic extrusion

Bolt Insertion Heaters

Best for controlled bolt expansion during heavy equipment assembly

Bolt insertion heaters use thermal expansion to safely and accurately tighten large bolts used in turbines, compressors, and heavy machinery. Designed with Incoloy-sheathed tubular heaters and protective outer shields, they operate at higher temperatures than conventional tubular heaters.

Key Features:

• Designed for high-temperature bolt heating
• Precise, uniform bolt expansion
• Custom diameters, lengths, and wattages available
• Proven performance on major industrial projects across North America
• Ideal for power plants, turbines, presses, large cylinders, and heavy construction
