Characteristics of chemical refrigeration and heating circulators

The chemical refrigeration and heating circulator system adopts an intelligent PLC microcomputer control system, which can be remotely operated and operated.
It is a commonly used refrigeration and heating temperature control equipment in the pharmaceutical chemical industry.
Then, what are the characteristics of the Wuxi Guanya chemical refrigeration and heating circulator? 1.
Fully enclosed system: The heat transfer medium is in a closed system, and the expansion tank with the heat transfer medium does not participate in the circulation process.
No matter it is high temperature or low temperature, the temperature of the expansion tank is always kept at room temperature of 60°C, which prolongs the service life of the heat transfer medium.

.

2.
Wide temperature range: only the same medium can be used to quickly control the temperature, and the temperature of the fluid system can be controlled within the range of -120℃~200℃.
The single compressor refrigeration technology can reach the temperature of -150℃, and the volume is smaller.
3.
Dynamic temperature control technology: The fluid dynamic control technology at the temperature measurement point ensures that the temperature accuracy of the liquid inlet and outlet and the material is only ±0.
5°C error.
When the temperature error is large, the control system will immediately issue The command controls the exothermic and endothermic reaction to achieve rapid response temperature control; 4.
High temperature cooling: directly use the compressor for refrigeration at a high temperature of 300 °C, and when the high temperature exothermic reaction occurs, the compressor can work for a long time to reach the control temperature, The effect of taking away excess heat; 5.
Pipeline circulation system: the use of plate heat exchangers and pipe heaters improves the power density ratio, reduces the use of heat transfer medium, and improves the response speed of system temperature control; 6.
Heating protection: The control system has multiple protections.
If the solid state relay fails, the control protection of the control system body will fail.
When the temperature exceeds the temperature value set by the deviation protector in the system, the deviation protector will turn the power supply of the solid state relay.
Cut off, once the protector also goes wrong, the independent control system will play its role, with this triple protection, there will be no high temperature overshoot
