CartridgeFamily

Watlow’s family of cartridge heatersprovides superior heat transfer; uniform temperatures and resistance to oxidation and corrosion even at high temperatures.Watlow’s cartridge heaters areavailable in high, medium and low-watt density units. The wattage distribution can be configured to yield a uniform heat profile and the overall superior construction allows for rapid heat dissipation into the former heater.

® sheath resists oxidation and corrosion from many chemicals, heat and atmospheres.• allows same dayshipment on more than 150,000 configurations of stock FIREROD heaters and lead combinations. • Nickel-chromium resistancewire, Minimal spacing between theelement wire and sheath UL resultsin lower internal temperature, giving you the ability to design with fewer or smaller heaters that operate at higher watt densities.• Magnesium oxide insulation of specific grain and purity, swaged to the proper density, results in high dielectric strength and contributes to faster heat-up. • precisely wound andcentered assures even, efficient heat distribution to the sheath.• Conductor pins metallurgicallybonded to the resistance wire ensure trouble-free electrical continuity. (The EB version features crimp-connected pins).•
® and CSA approved flexible stranded wires, with silicone-fiberglass oversleeve, insulate the wires to temperatures of 250°C (480°F). • Applications •Extrusion dies•Formers
