The engineers at Marathon Heater have developed a cartridge heater that exceeds the performance and durability of other cartridge heaters. Through refinements in the 1. swaging process,specially designed cores, carefulselection ofmagnesiumoxide fill, nickel chromium resistance wire, stainless steel tubing, and carefully controlled production processes,HotRodsroutinely outperformother cartridge heatersin difficult applications.

High temperature lead wires for temperatures up to 450° C. High impact ceramic cap retards contamination and is suitable for high vibration applications.

High purity magnesiumoxide fillselected for maximum dielectric strength and thermal conductivity, highly compacted for maximum heattransfer.

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 application guide in the 6. back for help in determiningwhichmaterial isbestfor your application.

Marathon Heater flexible heaters provide outstanding performance in applications up to 250°C under a variety of operating conditions. Properly applied silicone rubber heater life routinely exceeds 10 years. Silicone rubber has a high dielectric strength and is flame retardant and non-toxic. Design versatility permits special heat profiles allowing zones of higher or lower heat concentration as needed. Their flexible construction makes them very easy to install on a variety ofsurfaces. Silicone Rubber Heaters can be mounted to flat or curved surfaces. They are not affected by vibration, flexing or repeated mechanical shock.

High temperature oxidation resistant metal sheath. Highest grade mica insulation provides excellent electrical insulation at high temperatures and is resistant to moisture. Clamping band islow thermal expansion stainlesssteel construction designed to maintain clamping pressure at elevated temperatures. Nickel/Chromium resistance wire evenly wound for uniformheat distribution and reliable accuracy.

A blower assembly is used to distribute air in various kinds of equipment. It is commonly seen in cars, furnaces, and home appliances. During forging or furnace operation, air is the utility that should be available at all time in order to ensure a smooth and standardized operation.

Supplying air manually will reduce productivity and more man hour to accomplish a given task.

Coil heaters are an advance concept of thermal engineering, is also known as high performance tubular heaters or cable heaters. The basic construction of these heaters consist of compacted MgO, high temperature resistance wire and Chrome Nickel Steel tube. These heaters can be constructed with or without builtin thermocouples.

Marathon Mineral Insulated Heating Cables are the most rugged heating cable in Marathon's product line. Constructed of a solid series resistor element embedded in highly compacted mineral insulation, MI cables are built to handle high temperature, high wattage applications. The series resistor and mineral insulation are encased in a metallic jacket of INCONEL 600/800, SS304/316/321 or Copper for different high temperature or corrosive applications

Tubular elements are the most versatile of all metal sheathed heaters. They can be supplied inmany lengths, diameters,sheathmaterials and electricalratings. Inherent mechanical flexibility permits forming and bending into many shapes and sizes providing unique adaptability for the process engineer or product designer. Various sheath material selections are available to provide suitable operation from liquid immersion service through high temperature (871°C)radiant heating service.

Marathon Heater is pleased to present our line of premium temperature sensors. We offer standard and customized thermocouples, mineral insulated thermocouples, and RTDs. We use only the highest grade materials and offer a variety of sheath materials for any environment or temperature range. All sensors are subject to rigid quality control procedures and a thorough inspection process. Expert engineering assistance is readily available for any ordersize, largeorsmall.

In addition to many different standard heaters Marathon also offers unlimited variations in the form of customized heater designs. If your requirements call for unique physical attributes, special wattage or voltage ratings, Marathon can create a heater to fit your unique application. Many times we are able to incorporate design enhancements at little or no added cost. To help you become more familiar with our capabilities, please review photos of heater assembled below. They represent just a few ways we have helped other customers improve their process heating operations.

Marathon has successfully developed import substitute Mica Air Heater for drying plastic granule. Hot-air dryers have long been the natural choice forresinsthat have no affinity to moisture. Non-hygroscopic resins such as polyolefin's, polystyrene, and PVC pick up only surface moisture from condensation when exposed to high humidity and changing temperatures. Such surface moisture is easily removed by a stream of heated ambient air by the help of these Air Heaters
