Features • Square coil design for improved heat transfer • High watt density on nozzle … up to 106 watts/in 2 • Heat is conducted from entire heater circumference … 360˚ heat • Unheated tail section reduces temperature at adapter • Moisture-resistant seal • Low profile • 1200°F maximum operating temperature • Available for same-day shipping
This nozzle heater features a five-inch long unheated tail section, and the adapter is provided with a moisture- resistant seal. These two design advantages practically eliminate failures in the adapter area due to overheating and moisture contamination. As with all DME heaters, these new nozzle heaters are designed to give long life even when operated at 1200°F. These are very low profile heaters to facilitate easy installation in the tight environment of multiple gate molds. All units have a resistance tolerance of ±5% to provide consistent operation and reduced adjustment time when it is necessary to replace a heater or bushing.
