Coil heaters from the company feature a rectangular sheath, which enables wattage to be evenly distributed over the length of the injection nozzle assembly for optimum heat uniformity and improved material flow characteristics. Heater construction is designed for continuous high temperature (1,250°F) operation and extended use. The heater assembly is transitioned to flexible leadwires of Teflon or fiberglass insulation with an additional protective jacket of either heavy-walled fiberglass sleeving or stainless braid. Most designs feature an internal thermocouple for direct temperature detection, which is said to eliminate the need for a separate sensor.
