●Working Process
       The thermal oil heater directly inserts the electric heater into the organic carrier (thermal oil) for direct heating, and uses a high-temperature oil pump for forced liquid phase circulation to transport the heated thermal oil to the heat-using equipment, and then returns from the oil outlet of the heat-using equipment to the thermal oil furnace for heating, forming a complete circulating heating system. The thermal oil heater uses a digital temperature controller for temperature control, with over-temperature alarm, low oil level alarm, and over-pressure alarm functions. It is an energy-efficient heating device in industries such as chemical, textile, printing and dyeing, food, plastic, and film.
 
●Principle
       We emphasize that heat is generated and transmitted by the electric heating element immersed in the thermal oil. Using thermal oil as the medium and a circulation pump, the thermal oil is forced to undergo liquid phase circulation, transferring heat to one or more heat-using equipment. After being unloaded by the heat-using equipment, it returns through the circulation pump to the heater, 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 to meet the process requirements. Thermal oil heaters are mainly used in: petroleum and chemical industry, oil and fat industry, synthetic fiber industry, textile printing and dyeing industry, non-woven industry, feed industry, plastic and rubber industry, paper industry, etc.
