An explosion-proof electric heater converts electrical energy into heat to heat the required material. In operation, low-temperature fluid medium enters through the inlet under pressure, flows along the specific heat exchange channels inside the electric heating vessel, and carries away the high-temperature heat energy generated by the electric heating elements according to the path designed using fluid thermodynamic principles. This raises the temperature of the heated medium, resulting in a high-temperature medium at the outlet of the electric heater that meets process requirements. The internal control system of the electric heater automatically adjusts the output power based on the temperature sensor signal at the outlet to ensure uniform medium temperature. In the event of overheating of the heating elements, the independent overheat protection device immediately cuts off the heating power, preventing the overheating of the heated material from causing coking, deterioration, carbonization, and in severe cases, damaging the heating elements. This effectively extends the service life of the electric heater.

Typical applications for explosion-proof electric heaters include:

1. Chemical industry: heating and drying of chemical materials, drying of powders under certain pressure, chemical processes, and spray drying.

2. Hydrocarbon heating, including crude oil, heavy oil, fuel oil, thermal oil, lubricating oil, paraffin, etc.

3. Heating fluids such as process water, superheated steam, molten salts, nitrogen (empty) gas, water gas, etc.

4. Featuring advanced explosion-proof structure, the equipment is widely applicable in explosive environments such as chemical, military, oil, natural gas, offshore platforms, ships, mining areas, etc. Application Examples:
