Contact SupplierThis type of 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.
