The Watlow FIREROD not only sets the industry standard for cartridge
heaters, but continues to make improvements in construction and design.
Among those improvements is the FIREROD metric cartridge heater, a
variation of the FIREROD cartridge heater built to meet the exact
specifications of the global market.
Like its counterpart, the metric FIREROD consistently outperforms

maximize heat transfer. The end result is longer service life and better
