This desiccant air dryer provides an efficient, economical and easy to maintain method of drying compressed air and gases. The drying medium ( silica gel , activated alumina or molecular sieves ) is contained in two carbon steel pressure vessels. While chamber i is drying, air is passed over an electrical heater embedded in chamber ii and carries out the desorbed moisture of this chamber. This type of system utilizes about 2-3% of the compressed air as a purge. It is an ideal system for drying gases requiring ultra low drying up to ( -80°c) dew point. Each column remains in line for about 6-8 hours. For regeneration, the desiccant is heated for about 3-4 hours and then cooled for another 3-4 hours before changeover. The operation is fully automatic. A semi automatic operation with the help of selector switches can also be provided
