Cartridge Heaters

----Cartridge Heaters - Tier 1.jpgMagnum™ cartridge heaters are swaged designs, made for use in applications where high watt density, high temperatures and long service life are critical to minimize mold service downtime and expensive press open time. The swaged construction produces a highly compacted cartridge heater that resists shock and vibration, while providing for maximum element life through efficient transfer heating. Magnum cartridge heaters last up to 20 times longer than uncompacted cartridge heaters. UL/CUL Component Recognition Available. Durex will also custom manufacture cartridge heaters to your specifications.

Cartridge Heaters, Duraslik Non-Stick

The Duraslik non-stick coating eliminates the need for additional release agents to be applied to the heater prior to the insertion. The non-stick coating acts as a corrosion inhibitor and a solid lubricant on the inner diameter of the drilled hole when the heater is energized, allowing for reduced downtime...

Cartridge Heaters, Bolt Heaters

Bolt heaters are used to tighten large bolts that secure heavy machinery and equipment. The shaft of the heater is inserted into the hollow bolt and energized to expand it, which allows further tightening of the nut. This heater design is manufactured with specific diameter sheaths to fit industry standard...
