SR & ZLF series TCU Reactor Cooling Heating Temperature Control System
APLICACIONES
TCU temperature control system uses existing thermal energy (such as steam, cooling water and ultra-low temperature liquid - the "primary system") infrastructure to integrate into a single fluid system or secondary loop used to control the temperature of process equipment. It can achieve dynamic temperature control from -120℃ to 300℃.

WORKING PRINCIPLE
(Control the temperature of the reactor material)
- The method of changing the control set value can respond to the system lag in the process as quickly as possible and obtain a smaller system overshoot. The control consists of two sets of PID control loops, which are called: main loop and slave loop. The control output of the main loop is used as the set value of the slave loop. By controlling the temperature change gradient in this way, the temperature control accuracy of the system is guaranteed.
- The specially designed hysteresis predictor generates a dynamic signal yc(t) instead of the process variable y(t) as a feedback signal. Generate an e(t) signal for the controller, so that the controller predicts that the control action has no large lag.

FOR REACTOR SYSTEMS TEMPERATURE CONTROL
One host controls 5~60 different reactors
Non-contact temperature control system in the jacket of the reaction vessel
Each reactor is independently controlled and does not affect each other
