The wet air stream is split at the air dryer inlet through a differential valve. Part of this air / gas stream is passed through an external heater and heated to a regeneration temperature of 160-180°C, then it is fed to the desiccant tower under regeneration thus removing out the moisture from the desiccant bed. A water cooled / air cooled aftercooler  condenses the desorbed moisture which is discharged regularly through the automatic drain  . after condensation This stream joins the main incoming air stream and goes for drying to the  other tower under drying. Normally a Cycle time of 6+6 hrs is utilised to complete one cycle of operation.

After each operation the changeover is effected automatically.

APPLICATIONS  --

- Instrument air dryers for power plants refineries , chemical  & fertilizer plants etc.

- CNG Compressed Natural Gas Drying Dryers.
