Swaged Cartridge Heaters (HotRods)

The engineers at Backer Marathon have developed a swaged cartridge heater that exceeds the performance and durability of others in the industry.

Through refinements in the swaging process, specially designed cores, careful selection of magnesium oxide fill, nickel chromium resistance wire, stainless steel tubing, and carefully controlled production processes, HotRod cartridge heaters routinely outperform other heaters in difficult applications.

HotRod cartridge heaters are available in a wide variety of diameters and configurations. Choose from our 14,000+ stock heaters for immediate delivery or let the engineers at Backer Marathon design a unique cartridge heater for your special application. Standard manufacturing times are normally less than 2 weeks.

  • 1.
    High Temperature Lead Wires for temperatures up to 550°C
  • 2.
    High Impact Ceramic Cap retards contamination and is suitable for high vibration applications. Deep holes in cap prevent fraying of leads when bent
  • 3.
    Nickel-Chromium Resistance Wire for maximum cartridge heater life, evenly wound for even heat distribution
  • 4.
    High Purity Magnesium Oxide fill selected for maximum dielectric strength and thermal conductivity, highly compacted for maximum heat transfer
  • 5.
    304 Stainless Steel Sheath for oxidation resistance in a wide variety of environments. 316 Stainless Steel and Incoloy® are also available. Please consult the Sheath Suitability Chart to determine which material is best for your application
  • 6.
    TIG Welded End Disc to prevent contamination and moisture absorption

HotRods are UL recognized, File #E202904 and RoHS Compliant.
