A particular kind of compressed air drier called a refrigerated air dryer uses chilling to remove moisture from the compressed air. In order for it to work, compressed air is sent through a heat exchanger and cooled down to a temperature just below the dew point. The moisture condenses as a result of the air being cooled; it is then separated and removed from the system. Many businesses utilise chilled air dryers to supply dry, sterile compressed air for pneumatic tools, machinery, and equipment. They are a popular option for assuring the best possible air quality in industrial applications since they are effective, affordable, and able to manage a wide range of air flow rates.
