HT Elite spring flat coil heater are designed to the standard with respect to precise fit and profiling to optimize the performance of nozzles and other mating components. They accommodate type “J” or “K” type thermocouple that could be placed internally at the tip or the middle of a heater. They can be made as well to have profiled or distributed wattage configuration.
