The Importance of Clean, Dry Compressed Air How much water is too much? Any amount of water is too much. Water jeopardizes everything you want your compressed air system to do. It ruins product and fouls processes. • Relative humidity is the amount of water vapor in air relative to what it could hold at a given temperature • Moisture in compressed air remains in a vapor state through the compression cycle, so it is not a problem until it leaves the compressor Liquid remaining after the aftercooler: 14.7 gallons (32%) • Air discharged from a compressor is approximately 150°F to 450°F • At...

Principle of Operation for Sullair’s Desiccant Dryers Desiccant Heatless 6 Principle of Operation for Desiccant Heatless Dryers The dual tower design allows for continuous absorption of water from compressed air by using a hygroscopic high crush strength desiccant. Drying is accomplished by passing compressed air through the desiccant bed absorbing moisture while the other is being simultaneously regenerated with the expanded purge air. Left Tower Right Tower Regeneration of the desiccant is accomplished without the use of heat. The wet bed is dried by diverting a small amount of dry air...
