This dryer provides an
efficient, economical and easy to maintain method of drying compressed air and gases. The drying medium (Silica gel or
Activated Alumina ) 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 gas as a purge. It is an
ideal system for gases requiring ultra low drying like dew
points upto (-80°C). Each column remains in line for about 6
hours. For regeneration, the desiccant is heated for about 3
hours and then cooled for another 3 hours before changeover.
The operation is fully automatic. |
