A cartridge heater is a tube-shaped, industrial heating element that can be inserted into drilled holes. Cartridge heaters provide localized and precise heating. Watlow's FIREROD® cartridge heater revolutionised the heating element industry in 1954 when it was patented as the first swaged cartridge heater. The mechanical process of swaging reduces the heater’s diameter by compacting it, directly improving heat transfer and efficiency. These heaters are built with premium materials, tight manufacturing controls, and extensive quality assurance programs. They provide superior heat transfer, uniform temperatures, and resistance to oxidation and corrosion, even at high temperatures.
