Wet incoming gases after passing through filter pass through the slide piston valve assembly and are directed towards chamber I where they pass upward through the desiccant. Gas drying takes place by adsorption. Dry gas from chamber I then passes through the Check valve assembly and then through the after-filter to the application or work area.

While gas is being dried in chamber I the desiccant in chamber II where the desiccant has been wetted in the previous cycle is being simultaneously regenerated. The chamber II is depressurised to atmosphere through the purge valve in the downward direction. A portion of the dry gas passes through the needle valve/orifice plate through the desiccant and flushes out the desorbed moisture.

When the regeneration is complete, the purge valve is closed and the tower is slowly repressurised to line pressure for a smooth changeover. A drying period of 5 minutes provides an efficient dew point of -40°C or better (at atmospheric pressure ). In regeneration process approximately 60 seconds are required for repressurisation.

Heat of Compression type air dryer is a breakthrough in Drying technology. The hot air from the Compressor at 120°C and higher temp, is used directly for regeneration of the desiccant. After regeneration, this air is cooled down to 40°C and then it is dried in second tower. Thus the use of heaters is eliminated. For eg. in the 6+6 Hrs. Cycle the hot air is fed for regeneration for 4 Hrs. and for balance 2 Hr. a changeover takes place where the air is first cooled in cooler, then dried and before going to the outlet, cools the regenerated desiccant bed, thus bringing it down to ambient temperature. This cycle is reversed for the next 4Hrs. where the Adsorber drying the air in the previous cycle goes for regeneration and vice versa.

There is considerable power saving in this type of Air Dryers and the dew point is also better than the Refrigerated type of Dryers whereas, the power consumption is almost negligible.

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.

This dryer is similar to the Internal Heater type dryer except that no process air is wasted. For regeneration, a blower provides the atmospheric air which is pre-heated in an external heater, to regenerate the desiccant bed. Therefore no process air is used for regeneration. The unit is fully automatic.

The wet air stream is split at the dryer inlet through an differential valve. Part of this stream is passed through an external heater and heated to a temperature of 180°C, then it is fed to the tower under regeneration thus carrying away the moisture from the desiccant bed. A water cooler condenses the desorbed moisture. This stream joins the main incoming stream and goes for drying.

After each operation the changeover is effected automatically.
