Accutherm Nozzle Heaters

The heater consists of the following features:

1. • Standard voltage ratings are available from 120V to 277V. Wattage ratings to 600 Watts.
   • Precision wound nickel/chromium resistance wire type “A” 80% nickel 20% chromium. Suitable for operating temperatures of 1180° C or 2150° F. Designed for the maximum wire size, helical coil pitch, and centering in magnesium oxide matrix. Resistance wire fusion welded to alloy terminal pins providing a 360-degree circumferential weld bead.
   • Highest grade magnesium oxide with optimum compaction providing maximum electrical resistant properties coupled with excellent heat transfer characteristics.
   • The above parts are encased in an Incoloy® 840 alloy tube. The tube is roll reduced to a finished size and annealed for bending. Terminal ends of the element are over-sleeved to provide corrosion protection from the hot metal.
   • Element is assembled into a machined steel cup. The inside diameter of the cup is machined to close tolerances sized to fit your nozzle barrel. The standard unit will fit a 1.00″ diameter nozzle. Custom made units can be supplied for .750″ minimum to 1.125″ maximum nozzle diameter. Element is sealed into a cup using a 677 degree C or 1250 degree F heat transfer cement. The ends of the cup are welded with end disks providing a compact rugged assembly.
   • A wide variety of terminal leads are available. Standard leads are MG1000 (450 Degree C) nickel-clad copper conductors. Oversleeves of conduit or braided sleeving are available.
   • Units are designed and tested to meet CSA, UL, CE, and NEMA standards.
   • Also available with internal Type K thermocouple.
   • Units are made in the USA.
   • Standard unit delivery, 120V 500W for 1.00″ nozzle, with standard lead configuration, Stock to one week; contact factory for specials.
