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 element to maintain lower internal temperatures which results in smaller sized heaters operating at higher watt densities.
Constructed of high grade Nickel 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 refined swaging process, results in heaters with minimal air gap, high resistance to corrosion and oxidation, and increased life which makes Marathon make cartridge heater best in class with high performance and longer durability.
