Dual-tower desiccant dryers for the continuous dynamic adsorption of water vapor from compressed air. Using pressure swing adsorption technology (PSA)*, air gets dried under pressure by passing through one desiccant bed while the other bed is being regenerated. Regeneration of the wet desiccant is accomplished without the use of heat. A small portion of the dried process air, called purge, is passed through the wet desiccant bed at near atmospheric pressure. This super-dry air strips the desiccant of all previously adsorbed water vapor.
