Heat transfer oil is heated by electric heaters in the tank, then pumped to heat-consuming equipment via a high-temperature pump. After releasing heat, it returns to the tank for reheating. The PID controller monitors oil temperature in real time and adjusts heating power automatically to maintain a constant 200℃.
