Cartridge Tubular Heaters

Cartridge Tubular Heaters, also known as Single-Ended Immersion Heaters, are the optimal solution for heating applications where space is limited and two-ended wiring is impossible. Designed with a single-ended structure, these compact heating elements are inserted directly into pre-drilled holes in molds, rollers, or machinery blocks. Our cartridge heaters deliver high power density and rapid, uniform heating, making them the ideal choice for precision temperature control in confined industrial environments.

Cartridge Tubular Heater (Single-Ended Immersion Heater)
Cartridge Tubular Heaters, also known as Single-Ended Immersion Heaters, are the optimal solution for heating applications where space is limited and two-ended wiring is impossible. Designed with a single-ended structure, these compact heating elements are inserted directly into pre-drilled holes in molds, rollers, or machinery blocks. Our cartridge heaters deliver high power density and rapid, uniform heating, making them the ideal choice for precision temperature control in confined industrial environments.

Key Advantages of Our Cartridge Heaters

● Compact & Space-Saving Design: With a small diameter ranging from Φ3mm to Φ25mm and a tolerance of ±0.02mm, these heaters fit perfectly into tight spaces and standard mold cooling channels without modification.
● High Power Density: Despite their small size, they generate significant heat energy, capable of reaching temperatures up to 750°C (depending on sheath material), ensuring fast warm-up times and high efficiency.
● Precise Temperature Control: The close contact between the heater sheath and the drilled hole ensures excellent thermal conductivity and uniform temperature distribution, minimizing hot spots and maximizing product quality.
● Durable & Reliable: Manufactured using high-quality materials such as SUS304, SUS316, or Incoloy 800 sheaths, combined with high-purity magnesium oxide insulation, these heaters offer excellent resistance to oxidation and corrosion.
