Watlow Firerod

The FIREROD Cartridge Heater revolutionized the heating element industry in 1954 when it was patented as the first swaged cartridge heater. The mechanical procedure of swaging reduces the diameter of the heater by compacting the unit; this directly improves the heat transfer and efficiency of the heater.
