Watlow FIREROD Cartridge Heater

The Watlow FIREROD heater revolutionized the heating element when it was introduced. With
premium materials and tight manufacturing controls, it continues to
provide superior heat transfer, uniform temperatures, and resistance to oxidation and corrosion
even at high temperatures. The key to the success of the Watlow FIREROD is the unique swaging process used in its
manufacture. While many cartridge heater manufacturers now swage their products, Watlow has
developed its own unique swaging process. Swaging is a mechanical procedure that compacts the
MgO (magnesium oxide) insulation, which increases its thermal conductivity and enhances its
dielectric strength. Swaging has the added benefits of: permitting the resistance wire to operate at
lower temperatures, a critical factor in longer heater life; enabling users to achieve process
temperatures faster; providing more uniform heating to the application; reducing energy costs
through better heating efficiency; and, making the heater more durable and more resistant to shock
and vibration. Watlow FIREROD cartridge heaters are built using only the finest materials and construction
methods, and are backed with extensive quality assurance programs. Years of testing have proven
certain construction materials and manufacturing methods to yield the best performance. Due to Watlows tight manufacturing controls, Watlow FIREROD cartridge heaters can provide
the smallest “no heat” section – on both ends of the heater – of any cartridge heater manufacturer.
Watlow FIREROD cartridge heaters are available in 1/8-inch to 1-inch diameters (as well as
comparable metric sizes) and various lengths to cover different applications. Watlow is one of the
only companies to offer such a variety of specifications. Please contact us to order. To help us determine which
Watlow heater will best satisfy your application requirements, please determine as closely as
possible the overall length, diameter, watts, voltage, terminal option and lead length of the heater
you will need.
