Overview
TCU high and low temperature integrated machine is a new type of laboratory temperature control equipment, which has the function of heating and cooling simultaneously. It is mainly used to achieve temperature control of reaction vessels and other equipment to achieve the required reaction conditions.
Product Details
The TCU high and low temperature integrated machine adopts advanced refrigeration and heating technologies, which can quickly reach the required temperature and maintain temperature stability during the experimental process. The working principle is mainly based on the combination of refrigeration and heating technologies. It injects a certain amount of water or other medium into the device, and then cools the water through a refrigeration system, or heats the water through a heater. The cooled or heated water is pumped through a circulation pump to the equipment or system that requires temperature control to achieve precise temperature control.
TCU temperature control system:
1. Users can obtain a closed and repeatable temperature control within a wide temperature range, which can achieve temperature control from -90 ℃ to 280 ℃;
2. Avoiding the need for replacement and jacket maintenance of traditional equipment and facilities; High flow rate design; The thermal reaction delay is very small;
3. Built in electric heating and thermal oil auxiliary system, which can automatically turn on the auxiliary heating system according to needs;
4. Energy conservation can be achieved by accurately matching the heat requirements through rapid operation;
5. By quickly calculating and controlling the temperature of the entire reaction process, rapid response control can be achieved for exothermic and endothermic reactions that occur during the reaction;
6. Reserved with standardized interfaces, cold and heat source heat exchange modules can be added according to actual needs;
7. Adopting a fully enclosed pipeline design;
8. Formula management and production process recording can be carried out.

TCU's design features:
1. Closed constant pressure design:
The thermal expansion and contraction of a single medium in a closed system are automatically regulated by an expansion tank;
The secondary thermal conductive medium in a closed system does not come into contact with air, but only with the dry and clean inert gas inside the expansion tank;
It can reduce the risk of oxidation, absorption of moisture, or volatilization of thermal conductive media;
It can effectively improve the service life of the thermal conductive medium and avoid frequent replacement of the thermal conductive medium;
The selection of thermal conductive medium can ensure temperature regulation of the system within a large range (-30 ℃~180 ℃).
2. Energy saving design:
Using real-time data feedback from energy points, accurately calculating energy requirements, optimizing secondary medium control modes, and achieving significant energy savings while ensuring control accuracy. Simultaneously ensuring the repeatability of system operation and achieving stability in product quality.
3. Integrated design of pry and install
The system has been modularized and integrated into modules with minimal gaps
Directly connecting with the primary public medium and energy consumption system can ensure the normal operation of the system.
Modular design, combined with a wide range of temperature regulation, can achieve system maneuverability and flexibility.
The system occupies a small space and is easy and fast to install.
4. Formula based management
The control program can be programmed online, and users can adjust the operating curve according to their actual production process, automatically generate and save formulas.
Formula based management has achieved unmanned and fully automated process control, while also ensuring the confidentiality of process technology.
5. Optimization of Control Technology
The control process is complex and nonlinear, and traditional equipment exhibits time delay and difficulty in control.
The industrial fuzzy control technology using PID temperature control algorithm with feedforward can improve the temperature control accuracy to within ± 0.5 ℃ range.
The technical design of industrial fuzzy control relies on experience in system process design, temperature control debugging, and temperature control condition calculation.
The core control model and methods are derived from advanced and mature control technologies and design and debugging methods of European cooperative companies.
6. The system can achieve customized design
We can provide customers with different temperature control solutions based on their specific process and requirements for control accuracy, as well as the on-site usage environment requirements, combined with our company's design and commissioning experience.
The communication of the system is divided into two parts, one is the internal communication function of the system, and the other is the communication function with external systems (such as communicating with third-party DCS systems).
