Explosion-proof heating tube It is made of explosion-proof heating tube and explosion-proof junction box, consumption of electric energy into heat energy, so as to heat the material to be heated, the internal control system automatically adjusts the output power of the electric heater according to the temperature sensor signal of the output port, so that the medium temperature of the output port is uniform; When the heating element is overheated, the independent overheating protection device of the heating element immediately cuts off the heating power supply to avoid coking, deterioration and carbonization caused by overheating of the heating material, which causes the heating element to burn out in severe cases, effectively prolonging the service life of the electric heater.
