Metric FIREROD Metric Cartridge Heaters

Cartridge Heater Built to Meet the Specifications of the Global Market

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 other cartridge heaters with its design solutions such as its exclusive resistance wire winding and swaging process. These processes bring the resistance wire closer to the sheath and compacts the MgO insulation to maximize heat transfer. The end result is longer service life and better efficiency.

features & benefits


Nickel chromium resistance wire ensures even, efficient distribution of heat to sheath

Magnesium oxide insulation of specific grain and purity results in high dielectric strength and faster heat-up

Alloy 800 sheath resists oxidation and corrosion from many chemicals, heat and atmospheres

Minimal spacing between element wire and sheath results in lower internal temperatures and accommodates design with fewer or smaller heaters

UL® and CSA approved flexible stranded wires with lead insulation rated to temperatures of 250°C (480°F)


Nickel-chromium resistance wire

Assures even and efficient distribution of heat to the sheath because the wire is precisely wound and centered in the heater

Conductor pins

Ensures a trouble-free electrical connection because of the metallurgical bond between the conductor pins and resistance wire

Magnesium oxide insulation of specific grain and purity

Results in high dielectric strength and contributes to faster heat-up

Alloy 800 sheath

Resists oxidation and corrosion from many chemicals, heat or atmospheres

UL® and CSA approved flexible stranded wires

Insulates the wires to temperatures of 250°C (480°F)

Minimal spacing between the element wire and sheath

Results in lower internal temperatures and accommodates design with fewer or smaller heaters
