Application Occasions:
1. Heating and raising temperature of chemical materials in the chemical industry, drying of certain powders under pressure, chemical processes, and spray drying.
2. Heating of hydrocarbons, including crude oil, heavy oil, fuel oil, heat transfer oil, lubricating oil, paraffin, etc.
3. Heating of process water, superheated steam, molten salt, nitrogen (air) gas, water gas, and other fluids that require temperature increase.
4. Due to the adoption of advanced explosion-proof structures, the equipment can be widely used in chemical, petroleum, natural gas, offshore platforms, ships, mining areas, and other places requiring explosion-proof measures.
The electric heating tube should be properly positioned and fixed, and the effective heating zone must be fully immersed in liquid or solid metal. Dry burning is strictly prohibited. If scale or carbon deposits are found on the surface of the tube, they should be cleaned promptly before reuse to avoid affecting heat dissipation and shortening the service life.
3. When heating fusible metals or solid nitrates, alkalis, asphalt, paraffin, etc., the operating voltage should be reduced first, and only after the medium melts can the voltage be raised to the rated value.
4. When heating air, the elements should be arranged crosswise and evenly to ensure good heat dissipation conditions, allowing the flowing air to be fully heated.
5. When heating nitrates, safety measures should be considered to prevent explosion accidents.
6. The wiring part should be placed outside the insulation layer to avoid contact with corrosive, explosive media, and moisture; the lead wires should be able to withstand the temperature of the wiring part and the heating load for a long time, and avoid excessive force when tightening the wiring screws.

Working Principle:
It is a device that converts electrical energy into thermal energy to heat the material to be heated. During operation, the low-temperature fluid medium enters the input port through the pipeline under pressure, flows along the specific heat exchange flow path inside the electric heating container, which is designed based on fluid thermodynamics principles, and carries away the high-temperature thermal energy generated by the electric heating elements during operation, thereby raising the temperature of the heated medium. The outlet of the electric heater obtains the high-temperature medium required by the process. The internal control system of the electric heater automatically adjusts the output power of the electric heater based on the temperature sensor signal at the outlet, ensuring uniform temperature of the medium at the outlet. When the heating element overheats, the independent overheat protection device of the heating element immediately cuts off the heating power supply, preventing the heated material from overheating and causing coking, deterioration, or carbonization, which in severe cases could burn out the heating element, effectively extending the service life of the electric heater.Meltblown Fabric Air Heater
