Chinese Name

Flange Electric Heating Tube

Flange Electric Heating Tube (also known as plug-in electric heater): It uses U-shaped tubular electric heating elements, designed according to the specifications for heating different media, assembled on the flange cover based on power configuration requirements, and inserted into the material to be heated. The large amount of heat generated by the heating element during operation is conducted to the heated medium, raising its temperature to meet the required process requirements. When the medium temperature reaches the set value required by the process, the control system adjusts the output power of the electric heater through PID calculation based on the temperature sensor signal, achieving temperature control of the resistive load of the heating element. This ensures uniform medium temperature and meets the required requirements; when the heating element overheats or the liquid level is low, the interlock protection device of the heating element immediately cuts off the heating power supply to prevent the heating element from burning out, extending its service life.
