The refrigerated dryer is typically selected to achieve its design performance at the user’s most extreme working conditions (i.e. a warm summer day with the air compressor operating at the maximum load). The refrigerated air dryer can be used at both low and high levels of pressure and requires no processed compressed air during the air treatment. The refrigerated air dryer uses a set of heat exchangers or a single heat exchanger (with chambers), firstly, to pre-cool the air; secondly, to refrigerate the air to condense out moisture vapor; and finally, to re-heat the air to prevent pipe sweating downstream. Engineered to provide quality treatment for compressed air and eliminate costly contamination problems.
