Hot Rod Cartridge Heaters are designed to provide uniform heating and excellent heat transfer rate throughout the heating surface. Facilitated with individually controllable heating zones, various process requirements such as zone-specific heating and distributed wattage requirement can be achieved with precise and uniform temperatures. Heaters are constructed with minimal spacing between sheath and heating elements to maintain lower internal temperatures which result in smaller-sized heaters operating at higher watt densities.

Constructed of high-grade Nickle Chromium resistance wire wounded on specially designed cores, separated from metal sheath using high purity magnesium oxide fill, all centered and tightly compacted in SS/Inconel tubing through the refined swaging process, results in heaters with a minimal air gap, high resistance to corrosion and oxidation, and increased life which makes Marathon make cartridge heaters best in class with high performance and longer durability.

Application Areas



  • Semiconductor chamber heating

  • Semiconductor wire and die bonding

  • Freeze protection and deicing of equipment in cold climates or applications

  • Humidity control

  • Patient comfort heating used in medical devices

  • Metal die casting

  • Seal bars used in packaging equipment

  • High-temperature glass forming equipment



Construction



  • High-Temperature Lead Wires for temperatures up to 550° C

  • High Impact Ceramic Cap retards contamination and is suitable for high vibration applications. Deep holes in cap prevent the fraying of lead when bent.

  • Nickel Chromium Resistance wire for maximum life, evenly wound for even heat distribution.

  • High Purity magnesium oxide fill selected for maximum dielectric strength and thermal conductivity, highly compacted for maximum heat transfer.

  • Stainless steel sheath / Inconel sheath for oxidation and corrosion resistance in a wide variety of environments.

  • Tig welded end disc to prevent contamination and moisture absorption
