TCU Temperature Control System

The tcu temperature control system is different from the refrigeration and heating temperature control system. The temperature control process is the process of controlling the temperature of the materials in the reactor, and its principle is relatively simple. By changing the control setting value, the TCU can respond to the system lag in the process as quickly as possible and obtain a small system overshoot. TCU control consists of two sets of PID (each PID is variable) control loops, called the master loop and the slave loop respectively. The control output of the master loop is used as the set value of the slave loop.

TCU adopts three-point sampling (material temperature point, temperature control system outlet temperature, temperature control system inlet temperature), and combines a self-built model-free self-building tree algorithm with a universal anti-lag cascade algorithm. The TCU temperature control principle is as above. When selecting a TCU, you can choose a conventional model, isolation explosion-proof, or positive pressure explosion-proof TCU according to your own requirements.

The tcu temperature control system can achieve dynamic temperature control from -120℃ to 350℃. The system leverages existing thermal energy (such as steam, cooling water and ultra-low temperature liquids – known as “primary systems”) infrastructure integrated into a single system or secondary loop used to control the temperature of process equipment. This results in only one heat transfer liquid flowing into the jacket of the reaction vessel (rather than directly through steam, cooling water or ultra-low temperature liquid). The temperature of the entire reaction process is controlled by the operation.

1. Using a closed circulation system, the thermal fluid is not easily volatilized and oxidized at high temperatures, and there is no oil mist; it is not easily affected by environmental conditions at low temperatures, which can extend the service life of the thermal fluid.

2. High temperature/refrigeration: When the temperature drops from high temperature to low temperature, refrigeration can be started directly. Continuous operation and temperature control can speed up the experimental progress, save resources, and improve work efficiency.

3. The refrigeration heat exchanger adopts a fully brazed plate heat exchanger, which takes up little space and has high heat exchange efficiency.

4. The circulation pump adopts a high-temperature resistant oil pump, which has the advantages of high temperature resistance, low noise, and large flow rate.

5. Over-temperature protection, leakage protection, over-current protection and other protection functions fully ensure the safety of users and equipment.

6. Beautiful appearance, small size and reasonable structure.

7. The TCU temperature control system can provide air cooling and water cooling according to user needs.
