SUNDI -80℃~250℃

In comparison to other thermal control systems, Dynamic Temperature Control systems differ sometimes considerably in their thermodynamic characteristics. In practice, Dynamic Temperature Control systems offer definite advantages in your work: noticeably shorter heating and cooling times, better stability and reproducibility through the entire process chain, greater safety for expensive glass reactors and the contained substances, together with the simple and easy operation.

PRODUCTION WORKSHOP REAL MAP:

Typical application of refrigeration heating temperature control system

Dynamic thermostatic control of cold and heat source of high pressure reaction kettle, dynamic thermostatic control of double layer glass reaction kettle, and dynamic thermostatic control of cold and hot source of double-layer reactor.

Microchannel reactor thermostatic control, small temperature control system, steam - feeding system temperature control, material low temperature aging test.
The thermostatic control of the combined chemical cold source heat source, the cooling heating of the semiconductor equipment and the heating temperature of the vacuum chamber are controlled.

Advantages and functions of temperature control system of refrigeration

Temperature range from 120 to 350, performance superior, unique, high - precision, intelligent temperature control.
High cooling power from 0.5 to 1200kW, highest production stability and repeatable results.
Multi-function alarm system and safety function, use plate heat exchanger, tube type heater to increase heating and cooling rate.
7-inch and 10-inch color TFT touch screen graphics display, use magnetic drive pump, no re-seal leakage problem.
Full airtight system, extended thermal conductivity liquid life, very wide temperature range, no need to change liquid media.
Ultra-high temperature cooling technology can be cooled directly from 300 degrees of high temperature.
The principle and the function has many advantages to using staff: because only expansion of cavity in the body heat conduction medium contact with oxygen in the air (and expansion tank temperature at room temperature to 60 degrees), can achieve lower heat conduction medium absorbed by oxidation and the risk of air moisture.
No heat conduction medium evaporates at high temperature, and it can be achieved -80 ~ 190 degrees, -70 ~ 220 degrees, -88 ~ 170 degrees, -55 ~ 250 degrees, -30 ~ 300 degree continuous temperature control without pressurization.

Adopt full closed pipe design, adopt high efficiency plate heat exchanger, reduce the demand of heat conduction liquid, improve the heat utilization rate of the system, reach the rapid lifting temperature.Thermal conductive medium in a closed system, with a container, expand the heat-conducting medium not participate in circulation in the container, whether high or low temperatures, expansion tank temperature to room temperature to 60 degrees, can reduce the heat conduction medium in running the risk of absorb the moisture and volatile.

How to deal with the malfunction of Industrial Water Chiller System

What's wrong with the Industrial Water Chiller System when it fails to cool down? Let Guanya explain it to you below.

One reason is that the initial use of liquid chiller system fails to reduce the temperature, or there is something wrong with the installation of water-cooled chiller, cooling water tower, circulating water pump and pipe. It needs to be carefully checked according to the installation diagram.

The second reason may due to the pipes which are attached to various devices for a long time, and the impurities have accumulated in the water sources, resulting in smaller water flow. Therefore, we must clean the pipes between the devices.

Thirdly, If this problem occurs during the first use, it may cause by the wrong matching of the chiller and the problem of delivery. Because the industrial chiller has carried out 100% performance tests before getting out of the machine to ensure the normal operation of the machine unit.

Finally, If this is the case of a chiller that has been used for half a year or 1-2 years later, it may due to the leakage of Freon in the cooling system of the cold water machine. It is suggested to find out the leakage, weld it again and refrigerant. The heat exchanger of the water-cooled chiller is dirty and needs washing, and remember to clean it regularly after subsequent use.

The operation of any Industrial Water Chiller System is inseparable from the participation of refrigerant. So the shortage of refrigerant will affect the normal operation of the industrial chiller, and then result in the reduction of refrigerating capacity of the industrial chiller and even shut down, which is also the main reason for the shrinkage of the refrigerating capacity of the industrial chiller.
