Based on its function, the compressed air dryer market is segmented as follows: Dessicant dryer: These dryers are also known as regenerative desiccant dryers. The compressed air moves through a chamber filled with dessicant, which adsorbs the moisture, reducing the air dew point. Membrane dryer: Membrane dryers pass through a membrane material and removes water vapour through compressed air. These compressors are reliable, quiet and require no electricity to operate. Refrigerated dryer: Refrigerated air dryer removes moisture from the air with the help of a heat exchanger. The heat exchanger cools the air so that the vapour condenses into water.
