Hot RunnerNozzle <strong>Heaters</strong>FIREROD ®CartridgeThe Watlow FIREROD ®revolutionized the heating elementindustry in 1954 when it waspatented as the first swagedcartridge heater. With premiummaterials and tight manufacturingcontrols, the FIREROD heatercontinues to provide superior heattransfer, uniform temperatures andresistance to oxidation and corrosioneven at high temperatures.Cartridge heaters are available fromWatlow in both high- and low-wattdensity units and are traditionallyused as insertion heaters for moldsand hot runner nozzles. The wattagedistribution can be configured toyield a uniform heat profile and theoverall superior construction allowsfor rapid heat dissipation into themold or nozzle construction.Performance Capabilities• Temperatures to 760°C(1400°F) on Incoloy ® sheath• Temperatures to 540°C(1000°F) on optional stainlesssteel sheath• Watt densities to 62 W/cm 2(400 W/in 2 )Features and Benefits• Nickel-chromium resistancewire, precisely wound andcentered in the unit assures even,efficient distribution of heat to thesheath.• Conductor pins metallurgicallybonded to the resistance wireensure trouble-free electricalcontinuity.• Magnesium oxide insulation ofspecific grain and purity,swaged to the proper density,results in high dielectric strengthand contributes to faster heat-up.• Incoloy ® sheath resists oxidationand corrosion from manychemicals, heat and atmospheres.• Minimal spacing between theelement wire and sheath resultsin lower internal temperature,giving you the ability to designwith fewer or smaller heaters thatoperate at higher watt densities.• UL ® and CSA approved flexiblestranded wires, with siliconefiberglassoversleeve, insulate thewires to temperatures of 250°C(480°F).Conductor PinsNickel-ChromiumResistance WireMagnesiumOxide InsulationIncoloy ®Sheath• Patented Lead Adapter (LA)method allows same dayshipment on more than 150,000configurations of stock FIRERODheaters and lead <strong>com</strong>binations.Applications• Hot runner nozzles• MoldsIncoloy ® is a registered trademark ofSpecial Metals Corporation.UL ® is a registered trademark of Underwriter’sLaboratories, Inc.70
