Turn off the cold dryer or the air compressor first

When shutting down, it is usually recommended to close the air compressor first, and then close the cold dryer.

The reason for this is that the air compressor produces a large amount of compressed air during operation, which is cooled and dried by the cold dryer. If the cold dryer is turned off first, the compressed air produced by the air compressor will not be able to be effectively cooled and dried, which may lead to an increase in moisture and impurities in the compressed air, thus affecting the quality of the compressed air and the normal operation of the system. Therefore, in order to ensure the stability of the system and the quality of compressed air, the air compressor should be turned off first when shutting down, and then the cold dryer should be turned off after the compressed air is completely stopped.

The above information is for reference only, it is recommended to consult professionals to obtain accurate information. In addition, in the actual operation process, relevant safety specifications and operating procedures should also be followed to ensure the safety of personnel and equipment.
