Parameters Detailed

If the low temperature refrigeration system has been frosted, believing that some enterprises have met, then how should we deal with such situation? Are there any methods can solve this problem. Today, let’s know something about it with Guanya refrigeration company.

1. First turn off the suction valve of the low temperature box compressor and unload to the minimum number of cylinders to operate.

2. Then close the liquid supply valve of the intermediate cooler and close the suction valve of the small high pressure cylinder.

3. After the high pressure cylinder is returned to normal, open the suction valve of the large and low pressure cylinder again. When  the normal operation has been resumed, then supply the liquid to the intermediate cooler.

4. If the frosting of high pressure cylinder is severe, the operation of the unit must be stopped.

5. Drain the intermediate cooler.

6. The cooling water treatment is the same as the single-stage treatment.

Do you remember the above way of processing? If you still have some questions, please contact the customer service on the official website of Guanya refrigeration company immediately, and solve the problem in time!

Working Principle

Applications

It is used in industrial cold treatment, mainly in the application of cold work mold steel, high-speed steel, bearing steel, cold work molds and mold accessories;


This industrial cold treatment box can significantly increase the hardness and strength of the workpiece, ensure the dimensional accuracy of the workpiece, improve the wear resistance and impact toughness of the workpiece, and improve the stress distribution within the workpiece;


Mainly used for cold shrinkage of copper sleeves, bearings, etc., and widely used in precision machinery assembly;


It is also widely used in ultra-low temperature testing of large equipment (automobiles, large engineering machinery, aircraft components, aerospace equipment components, military equipment components);
