In Desiccant Air Dyers, the compressed air is passed through a pressure vessel filled with an adsorbent media such as activated alumina, molecular sieve or other desiccant material. Two vessels with desiccant are used. The desiccant can bring the dew point of the air down to -40 degrees Celsius or below. This means that the air will not condense water until it is cooled to -40 degrees Celsius. Wet air enters the vessel through a pre-filter to remove any oil and other contaminants which protects desiccant’s long life. Pre-filtered air enters into adsorption tower through solenoid valves controlled by an electronic timer. In practice two vessels are used; one vessel is drying the air, while in the other the moisture absorbed by the adsorbent in the vessel is being regenerated. After a pre-determined period of time the switching of the vessels takes place with the help of the electronic timer. The other absorber tower undergoes regeneration with a portion of dry air exits from adsorption tower. This regenerated air is purged out of the system.

We are counted among well-reckoned Manufacturers and Supplier of Desiccant Dryer. Desiccant Dryer, offered by us, is fabricated with great perfection using top grade components. Desiccant Dryer is known for its high performance and low maintenance. Moreover, the Desiccant Dryer is tested stringently on various quality parameters. Silent Features : Constant Atmospheric Dew Point of (–)40oC Minimum loss of purged airLong life desiccant which gives desired dew pointEasy to Operate or Troubleshoot Designed as per ASME Sec VIII Div 1 Low Maintenance costLow Power Consumption The wet air with inlet temperature of 40oC enters the pre Filter. Pre-Filter is necessary prior to the dryer, as it removes oil and other contaminants. This actually protects the Desiccant from deteriorating, thus increasing the life of desiccant. The pre-filtered air then enters the adsorption tower through a 3-way diaphragm control valve. As the air flows through the tower the moisture is adsorbed from the wet air. This dry air then passes through the After-Filter, which removes any desiccant dust carry over. Meanwhile the other Adsorber tower is undergoing regeneration, with a part of dry air coming out of the tower under adsorption. This air is then purged out through muffler. The atmospheric dew point achieved is around (-) 40oC. How does it work? Rust and pipe scale deposits in steel pipes, increased resistance to flow, malfunctioning of pressure control equipment, corrosion in electromagnetic valves, solidification of media in pneumatic conveying systems, bubbling or orange peel effect in paint spraying are all consequences of water in the compressed air system. It not only endangers your delivery dates but quickly soaks up profits. Air drawn into the compressor will, depending upon the relative humidity, contain 60% to 80% of water vapour. Under compression, some of this converts to water and can be removed by line filters. However, as the temperature drops, water vapour will re-appear as condensation. Water vapour can only be economically removed by two methods : one is by cooling the air; the other more efficient method is by adsorption. The Puriflair range comprises of both Refrigeration Dryers and adsorption dryers. Refrigeration Dryers are used for application requiring air with pressure dewpoints to +2oC. Adsorption dryers provide a much lower pressure dewpoint, from -20oC to -40oC, at a relative compressed air humidity of only 0.1%. These are available as Heatless, Heat regenerated (Reduced Purge Air), Heatregenerated and Energyless;
