Miniature Cartridge Heater Provides Maximum Performance

Watlow® features a miniature version of the Watlow FIREROD® cartridge heater. The 1/8-inch FIREROD features a helically wound resistance wire that produces higher watt densities and contributes to longer service
life in space-restricted applications.

Industry trends show a reduction in medical equipment size and a movement toward manufacturing more ambulatory equipment continues. Watlow’s 1/8-inch FIREROD is compatible with the reduced equipment size.
It also features an 1/8-inch diameter and an internal thermocouple option for temperature control, which is an ideal solution for space limitation problems.

Small FIREROD heaters have the ability to work at a high watt density without compromising service life. This makes the heater ideal for space-restricted applications within the aviation, packaging, freeze protection, ink jet printer and gas chromatography industries.

Similar to other FIREROD cartridge heaters, Watlow’s 1/8- inch FIREROD sheath is resistant to oxidation and corrosion, even at high temperatures. It also undergoes a swaging procedure that is designed to improve dielectric strength, heat transfer and tolerance to shock and vibration. Users can achieve desired process temperatures more quickly, and the resistance wires operate at lower temperatures, which is ideal for reducing energy costs and an important factor in determining heater life.

Watlow’s 1/8-inch FIREROD is available with crimped-on or swaged-in leads with optional Teflon® moisture resistant seals and leads. Mounting options include a one-inch diameter mounting flange (FS flange), and a
90° angle-bend version.
