Coil Heater Sealed Nozzle Brass Band Heater
The Yuheng pre-coiled, cable nozzle heater has been formed into a compact, tightly wound coil to supply 360 degrees of heat. This heater features a 5 in. (127 mm) long, no-heat tail section, which eliminates failures in the adapter area due to overheating.
This cable nozzle heater is manufactured with Yuheng’sswaged compaction process. This process provides a greater compaction of the MgO insulation than the competitor’srolling process. Compacting MgO insulation into a solid mass results in excellent heat conductivity and high dielectric strength.
