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
APPLICATIONS
New materials | Special gas production temperature control
New materials, as newly developed or developing structural materials with excellent performance and functional materials with special properties, have extremely high requirements for temperature control in their research and development and production processes. The production of special gases, such as oxygen, nitrogen, argon and other industrial gases, also requires precise temperature control to ensure product quality and production efficiency.
API | intermediate production temp control solution
In the production process of raw materials, many chemical reactions need to be carried out within a specific temperature range. For example, in the production of antibiotics, even a slight change in temperature may affect the growth rate of the bacteria and the activity of the product. Therefore, the use of high-precision temperature control systems, such as high and low temperature all-in-one machines or temperature control reactor oil temperature machines, has become the key to ensuring smooth production. These devices have built-in high-precision temperature control systems and use PID temperature control technology to achieve a temperature control accuracy of ±0.1°C, ensuring that each chemical reaction can be carried out at the appropriate temperature.
Distillation concentration temperature control solution
The basic principle of distillation and concentration is to utilize the difference in volatility of the components in the mixture, vaporize the volatile components under heating conditions, and then collect them through condensation to achieve the purpose of separation and concentration. In this complex and delicate process, temperature control technology is not only the key to ensure smooth operation, but also an important factor affecting product quality and efficiency.
