Compressed Air & Gas Drying Systems
Heatless Type Air Dryer
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.
High Pressure Air / Gas Dryer For various industrial applications where Air / Gas at high pressure in dry form is required, Airox Nigen offers High Pressure Air / Gas Dryers. High Pressure Dryers are available in Heatless type.
Some of the High Pressure Industrial Applications are:
Heat Of Compression Type (HOC)
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.
Internal Heater Type (IHD) Air Drying
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.
Blower Heat Regenerated Type (BRD) Air Dryer
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.
Refrigerated Type Air Dryer
As much as 2300 gallons of water can be removed from a100 cfm system operating at 100 psi in 12 months of 3 shift operation, water which without a dryer, would have passed through pneumatic equipment
Wet Compressed air undermines efficiency of smallest to the largest system. Therefore, elimination of moisture is must. The drying of Compressed air by Airox Nigen Refrigerated Air Dryer is the most economical and reliable process of compressed air treatment. The incoming saturated, moist air is precooled in the Air-to-Air Heat Exchanger (6) by the outgoing dry chilled air. In the process, a greater part of Water Vapour get condensed. Further moisture separation takes place in the Freon-to-Air Heat Exchanger (7) where air is chilled to a temperature of +2 Deg. C. and moisture condenses. This temperature is termed as pressure 'Dew Point'. The Separator (8) removes the condensate by an Automatic Condensate Trap (12)
The compressed dry air is reheated in Air-to-Air-Heat Exchanger and fed to the point of application. As long as compressed air temperature remains above the +2 Deg. C., no further condensation will occur. The Dew Point of +2 Deg. C. is sufficient enough for the smooth and trouble free pneumatic / process applications. The refrigeration circuit is the conventional circuit comprising refrigerant Compressor (1), Condenser (2), Expansion Valve (5) etc.using Freon R-22 as refrigerant gas. Use of R-22 as a refrigerant is permissible upto the year 2030 AD as per Montreal Protocol. System with Ecofriendly Refrigerant like R-134 A, R-404 A, R-407C are also offered. Air Cooled (AC) models are available upto 200 CFM and higher models are available with water cooled condenser.

Split Flow-No Purge Loss Type (SFD) Air Dryer
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.
