Cartridge Heater

Cartridge Heaters are tubular heating elements designed to deliver efficient, precise, and controlled heating in a wide variety of industrial applications. These heaters consist of a high-quality resistance coil insulated with compacted materials and enclosed within a metal sheath, ensuring excellent thermal conductivity and electrical safety.

They are available in two types:

  • High Density Cartridge Heater
    • Built using high-purity MgO (Magnesium Oxide) insulation densely packed around the resistance coil.
    • Supports high watt densities and elevated operating temperatures (up to 800°C).
    • Designed for demanding industrial applications requiring durability and uniform heating.
  • Low Density Cartridge Heater
    • Uses ceramic powder insulation with lower compaction
    • Ideal for general heating requirements, where extreme watt density is not necessary.

Advantages

  • Versatile – Suitable for both high-performance (high density) and generalpurpose (low density) applications.
  • Efficient – High thermal conductivity ensures fast and uniform heating.
  • Durable – Corrosion-resistant sheath materials extend service life.
  • Compact Design – High watt density allows more power in smaller space.
  • Customizable – Wide range of diameters, lengths, and terminations available.
  • Energy Saving – Quick response time reduces heat-up cycles and saves energy.
  • Low Maintenance – Reliable performance with minimal downtime.

Applications

  • Plastic Industry – Injection molding, hot runner systems, sealing bars.
  • Packaging Machinery – Cutting, sealing jaws, shrink tunnels.
  • Food Processing – Heat sealing, food-grade heating equipment.
  • Medical Equipment – Sterilizers, diagnostic and testing devices.
  • Laboratory & R&D – Precision heating in analytical equipment.
  • Industrial Heating – Dies, molds, platens, fluid heating systems

Features

  • Available in High Density and Low Density variants.
  • Excellent heat transfer and uniform heat distribution.
  • High watt density for compact heating requirements.
  • Long life due to durable sheath and high-grade insulation.
  • Corrosion and oxidation resistant.
  • Customizable in diameter, length, wattage, voltage, and termination.
  • Options for right-angle, straight, or flexible lead exits.
  • Quick heating response and efficient energy utilization.
