Parameters Description
Full closed pipe design is adopted.According to the instructions given by the system PLC, turn on the Angle of the electric control valve and control the flow of the cryogenic liquid into the reactor jacket, thus achieving energy saving and efficiency.All the signals in this process are based on temperature. To ensure the safety operation of the system, electric hair can be fully opened by hand.
TCU temperature control system USES the existing heat (such as steam, cooling water and cryogenic liquid – the “primary”) system infrastructure are integrated into the single fluid system was used to control the temperature of process equipment or in the secondary loop.This achieves only one type of heat transfer liquid can flow into the jacket of the reaction vessel (not directly flow into steam, cooling water or ultra-low temperature liquid).The temperature of the whole reaction process is controlled by operation.

Working Principle
Through three-point sampling (material temperature point, temperature control system outlet temperature, temperature control system inlet temperature), through our company’s own model-free self-built tree algorithm and general anti-lag cascade algorithm.
ZLF Application
Use area: can be used in various explosion-proof areas
The temperature control unit (TCU) is mainly used in reactor heating, cooling temperature control in fine chemical, chemical pharmaceutical, and biopharmaceutical processes. It can realize automatic control of temperature rise, temperature drop, constant temperature and distillation during the reaction process, especially suitable for the reaction process. There is a process control that requires heat and heat.
