It is the simplest form of dessicant type gas or air dryer for achieving a dew point
of -40°c or better for compressed air systems and other gas and air dryer applications.
Process: In this dryer two desiccant towers are used. While one tower is
in drying, second tower undergoes regeneration simultaneously. Part of dry air coming
out from tower in-line goes for regeneration of the second tower. Tower changeover
takes place at every 5 minutes by a sequence controller mounted in control panel.
