Hot RunnerNozzle <strong>Heaters</strong>Coiled CableThe versatile Watlow cable heatercan be formed to a variety of shapesas dictated by its many applications.Cable heaters are small diameter,high performance units, fullyannealed and readily bent to amultitude of configurations.The heater can be formed into a<strong>com</strong>pact coiled nozzle heater foruse on plastic injection moldingequipment supplying a full 360degrees of heat with optionaldistributed wattage.Different applications requiredifferent construction methods,including one, two, three or fourresistance wires; parallel coil orstraight wire; drawn or swagedsheaths; with or without internalthermocouples; leads exiting fromone or both ends, and round,rectangular or square cable sheaths.Whatever the application, theWatlow cable heater can be shapedto fit your application needs.Performance Capabilities• Continuous operating temperaturesto 650°C (1200°F) with intermittentoperating periods achieving up to815°C (1500°F). Dependent ontype of element wire used.• Sheath watt densities on the cableto 4.65 W/cm 2 (30 W/in 2 ), and ashigh as 11.62 W/cm 2 (75 W/in 2 )within factory approved conditions.Features and Benefits• High ductility allows the heater tobe cold-formed into almost anyshape.• The heaters low mass allows forquick response to both heatingand cooling.• Standard 304 stainless steel,optional 316L stainless steel orInconel ® 600, provide high temperaturecorrosion and oxidationresistance along with idealthermal expansion properties.66Straight Resistance WireWeldedEnd CapORParallel CoiledResistance WireSheath• The heater sheath can bebrazed allowing the permanentattachment of mounted fittings tothe heater. Consult factory foradditional information.• Ranging from 1 mm (0.040 in.)to 5 mm (0.188 in.) diameter,the cable heater packs a lot ofheat into a tiny space.
