Cartridge Heaters

----Cartridge HeatersMagnum™ cartridge heaters are swaged designs, made for use in applications where high watt density, high temperatures, and long service life are critical to minimizing mold service downtime and expensive press open time. The swaged construction produces a highly compacted 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 heating elements. UL/CUL component recognition available. Durex will also custom manufacture designs to meet your specifications.

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.
