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. PLC controls are available as option.
APPLICATIONS - Ultra low Dew Point drying of Air &
Gases Like NITROGEN , ARGON, CARBON DIOXIDE CO2 , NITROUS OXIDE, OXYGEN etc.
