Square Swaged Cartridge Heaters

Square Swaged Cartridge Heaters
Unlike square cartridge heaters from other manufacturers, our square cartridge heaters are swaged, allowing them to be used in high temperature and high watt density applications. Square heaters are ideal for milled slots in long platens where drilling a long hole would be too difficult. Square cartridge heaters are also much easier to remove from a slot after extended high temperature usage than removing a round heater from a drilled hole.
