CartridgeFamily

Watlow’s family of cartridge heatersprovides superior heat transfer;uniform temperatures and resistanceto 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 heated parts such as seal bars.

(The EB version featurescrimp-connected pins). • precisely wound and centered assures even, efficient heat distribution to the sheath.•
® sheath resists oxidation and corrosion from many chemicals, heat and atmospheres.• Minimal spacing between theelement wire and sheath resultsin lower internal temperature,giving you the ability to designwith fewer or smaller heaters that operate at higher watt densities.• UL Applications •Seal bars•Form, fill and seal •Adhesive heating and dispensing •Hole punching
