The Industrial Helical Coil Thermal Oil Heater is a highly efficient and reliable heating system designed for industrial applications that require uniform and precise temperature control. Using thermal oil as the heat transfer medium, it provides indirect heating at temperatures up to 200–350°C under low operating pressure. The heater features a helical coil structure, ensuring optimal heat transfer, compact design, and long service life. It is widely used in industries such as chemical, textile, food, plywood, bitumen, and oil processing.
