Refrigeration dryers use a refrigerant gas in order to cool the compressed air. As a result the water from the air condenses and can be removed. With this technique we can reach a pressure dewpoint of 3°C with the DRY range. Refrigeration dryers are the most commonly used dryer technology for workshops, bodyshops and general industry. In conjunction with the correct grade filtration compressed air can be supplied as clean dry air free of contaminants.
