Applications:
1. Heating and temperature raising 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, thermal oil, lubricating oil, paraffin, etc.
3. Process water, superheated steam, molten salt, nitrogen (air) gas, water gas, and other fluids requiring heating and temperature raising.
4. Due to the use of advanced explosion-proof structure, the equipment can be widely used in chemical, petroleum, natural gas, offshore platforms, ships, mining areas and other places requiring explosion protection.
The electric heating tube should be properly positioned and fixed, and the effective heating area must be fully immersed in liquid or solid metal. Empty burning is strictly prohibited. If scale or carbon deposits are found on the tube surface, they should be cleaned promptly before reuse to avoid affecting heat dissipation and shortening service life.
3. When heating fusible metals or solid nitrates, alkalis, asphalt, paraffin, etc., first reduce the operating voltage, and only after the medium melts can it be raised to the rated voltage.
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. Safety measures should be considered when heating nitrates 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 channel inside the electric heating container, following the path designed based on fluid thermodynamics principles, and carries away the high-temperature thermal energy generated by the electric heating element during operation, thereby raising the temperature of the heated medium. 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 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, coking, deteriorating, or carbonizing, which could otherwise damage the heating element, effectively extending the service life of the electric heater.Meltblown Fabric Air Heater
