Marathon Non-Swaged Cartridge Heaters

Non-swaged cartridge heaters offer a cost effective solution where the superior performance of a swaged heater is not required.  Non-swaged heaters can be used at watt densities up to 45 watts per square inch and temperatures up to 1000°F.  Non-swaged heaters offer tighter length tolerances than swaged heaters, making them ideal for applications such as platens where heaters are generally longer.  Non-swaged heaters can be built with 3 independent heat zones, distributed wattage, and/or internal thermocouples. Most of the lead configurations and options available for swaged Hotrod heaters are also available for non-swaged cartridge heaters. Non-swaged heaters are not recommended for applications where there is is a lot of vibration or impact.

• Lead wires are UL rated to 550°C (1022°F)
• High temperature cement filling protects leads and internal parts.  Epoxy and silicon rubber leads are available.
• Nickel chromium resistance wire stretched evenly throughout the length for even heat distribution.
• High purity MgO is vibratory filled for maximum heat transfer.
• 304 SS sheath for superior oxidation resistance.
• Welded end disc to prevent contamination and moisture absorption.
