High-Performance Swaged Cartridge Heating — Up to 760°C

The Watlow FIREROD cartridge heater is the premier choice in swaged cartridge heating, backed by over 60 years of proven performance in demanding industrial applications. With part temperatures up to 760°C (1400°F), watt densities up to 62 W/cm², and a corrosion-resistant Alloy 800 sheath, the FIREROD delivers superior heat transfer, uniform temperatures and long service life where it matters most.

Key Features

* Optional built-in temperature sensor — An internal thermocouple can be located at the disc end or anywhere along the heater length for accurate, at-the-source temperature readings. Ideal for sensitive, zoned or uniform-temperature applications, and reduces assembly size and cost by eliminating a separate sensor.

* Straight and right-angle construction — Choose the lead exit configuration that suits your installation, including right-angle designs for tight or space-constrained equipment.

* Metric and imperial sizes — Available in diameters from 1/8 in. to 1 in. (3 mm to 25 mm) and lengths from under 25 mm to 2540 mm (1 in. to 100 in.) — one of the widest size ranges in the industry.

* Heats up to 760°C (1400°F) — Standard Alloy 800 sheath resists oxidation and corrosion at high temperatures, outperforming the stainless steel sheaths used by other manufacturers.

* Custom heaters available — With more than 250,000 design variations manufactured to date, Watlow can engineer a FIREROD to your exact voltage, wattage, size, lead and sealing requirements — including special seals, sheath materials and multi-zone designs.

Built to Last

Every FIREROD is swaged for maximum thermal conductivity, using precision-wound nickel-chromium resistance wire and high-purity compacted MgO insulation for high dielectric strength and fast heat-up. Manufactured under ISO 9001-certified quality controls, with UL® and CSA approved lead wires.
