why choose lneya
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.

Using single fluid heat transfer control system has the following advantages:

A. The user can obtain a closed and repeatable temperature control at a wide temperature range, which can achieve the temperature control of -120 degrees ~ 300 degrees;
B. Avoid the replacement of traditional equipment and the requirement for jacket maintenance;The smaller fluid volume also guarantees the quick response of the control loop and the thermal response delay is small.
C. The built-in electric heating oil auxiliary system can automatically turn on the auxiliary heating system according to the requirements to reduce the steam pressure;
D. can achieve the energy saving purpose by fast running accurate matching of each heat demand;
E. Control the temperature of the whole reaction process by accurate and fast operation, and the rapid response control is carried out during the whole reaction process.
F. There is a standardized interface, which can increase the heat transfer module according to the actual demand;
G. the temperature of the control reaction process and the single fluid temperature can be selected, and the temperature difference between the temperature of the reaction process and the temperature of the thermal conductivity can be controlled.
H. can carry out recipe management and production process record;
A. Full closed pipe design is adopted.
B. 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.
C. To ensure the safety operation of the system, electric hair can be fully opened by hand.
2) temperature process control principle (control reaction kettle material temperature)
