Immersion heater coil
Operating principle of coil heater
immersion heater coil
The square coil heater is designed to meet standards, with accurate installation and profile design to optimize the performance of the nozzle and other supporting components.They accommodate type “J” or “K” thermocouples that can be placed inside the top or middle of the heater.
