Refrigerated air dryers are devices used in compressed air systems to remove moisture from the air. They work by cooling the compressed air, which causes water vapor to condense into liquid water. This liquid is then separated and drained away, preventing moisture from damaging equipment or affecting processes. These dryers are commonly used in various industries, including manufacturing and automotive, to ensure the quality of compressed air. By maintaining a low dew point, refrigerated air dryers help protect tools and machinery, enhancing their performance and longevity while reducing maintenance costs.
