Thermal oil electric heater is a direct-fired special industrial furnace that uses coal, heavy oil, light oil, combustible gas, or other combustible materials as fuel and thermal oil as the heat carrier. It uses a circulating oil pump to force liquid-phase circulation, transferring heat energy to the heat-using equipment, and then returning to be reheated. Thermal oil, also known as organic heat carrier or heat transfer oil, has been used as an intermediate heat transfer medium in industrial heat exchange processes for more than fifty years. An organic heat carrier furnace is a new type of special boiler that uses heat transfer fluid as the heating medium. It has the characteristics of low pressure and high temperature operation. With the development of industrial production and the advancement of science and technology, organic heat carrier furnaces have been continuously developed and applied. Although the working pressure of the organic heat carrier furnace is relatively low, the temperature of the heat transfer fluid inside the furnace is high, and most of them are flammable and explosive. Once leakage occurs during operation, it may cause fire, explosion, and even casualties and property losses. Therefore, the safe operation and management of organic heat carrier furnaces must be highly valued. The thermal oil electric heater is a new type, safe, high-efficiency, energy-saving, low-pressure (normal pressure or lower pressure) special industrial furnace that can provide high-temperature heat energy. It uses thermal oil as the heat carrier and circulates the heat carrier through a hot oil pump to transfer heat to the heat-using equipment.
The electric heating thermal oil furnace system consists of a explosion-proof electric heater, organic heat carrier furnace, heat exchanger (if any), on-site explosion-proof operation box, hot oil pump, expansion tank, etc., combined into a skid. Users only need to connect the power supply, inlet and outlet pipelines of the medium, and some electrical interfaces to use it.

Working Principle
For the thermal oil heater, heat is generated and transmitted by the electric heating elements immersed in the thermal oil. Using the thermal oil as the medium and the circulation pump, the thermal oil is forced to circulate in the liquid phase, transferring heat to one or more heat-using equipment. After being unloaded by the heat-using equipment, it returns to the heater through the circulation pump, absorbs heat again, and transfers it to the heat-using equipment. This cycle repeats, achieving continuous heat transfer, raising the temperature of the heated object, and meeting the heating process requirements. [
