Bolt Heating Rod Overview and Product Features

Darui Electric recommends　　

Thermal Oil Heater is a new type, energy-saving, low-pressure (at normal pressure or lower pressure) special industrial furnace that can provide high-temperature heat energy. It uses electricity as the heat source and thermal oil as the heat carrier, forcing liquid-phase circulation through a circulating oil pump. After transferring heat energy to the heat-using equipment, it returns to be reheated, forming a direct-current special industrial furnace. This cycle repeats, achieving continuous heat transfer, raising the temperature of the heated object to meet the heating process requirements.

　　Structure and Principle: The system consists of an explosion-proof electric heater, an organic heat carrier furnace, a heat exchanger (optional), a control cabinet, a hot oil pump, an expansion tank, etc., combined into a skid. The user only needs to connect the power supply, the inlet and outlet pipes of the medium, and some electrical interfaces to use it.

　　The thermal oil heater directly inserts the electric heater into the organic carrier (thermal oil) for direct heating. Using a circulating pump, it forces the thermal oil to undergo liquid-phase circulation, transferring heat to one or more heat-using devices. After the heat is unloaded by the heat-using devices, it returns through the circulating pump to the heater, absorbs heat again, and transfers it to the heat-using devices. This cycle repeats, achieving continuous heat transfer, raising the temperature of the heated object to meet the heating process requirements.

　　The thermal oil heater uses a digital temperature controller for temperature control, with functions such as over-temperature alarm, low oil level alarm, and over-pressure alarm. It is an energy-saving heating equipment in industries such as chemical, petroleum, machinery, printing and dyeing, food, shipbuilding, textile, and film.
