Pipeline electric heater is an energy-saving device that generates heat by electricity and then pre-heats the material. It is installed in front of the material device to realize the direct heating of the material, so that it can circulate at high temperature, and finally achieve the purpose of saving energy.

Working principle: 

Explosion-proof electric heater is a kind of material to be heated by converting electric energy into heat energy. In operation, the low-temperature fluid medium enters its input port through the pipeline under the pressure, and along the specific heat exchange channel inside the electric heating container, it takes away the high-temperature heat energy generated by the electric heating element in operation, so that the temperature of the heated medium rises, and the high-temperature medium required by the process is obtained at the outlet of the electric heater. The internal control system of the electric heater automatically adjusts the output power of the electric heater according to the signal of the temperature sensor at the output port, so that the medium temperature at the output port is uniform; When the heating element overtemperature occurs, the independent overheat protection device of the heating element immediately cuts off the heating power supply, so as to avoid coking, deterioration and carbonization caused by overtemperature of the heating material, and even burn out the heating element in severe cases, effectively prolonging the service life of the electric heater.
