Dewpoint demand switching is an operating mode for twin-tower desiccant compressed air dryers which causes the towers to switch based on the dewpoint instead of switching based on time. This article discusses why this operating method can cut compressed air plant operating costs by 20% in some cases and demonstrates how this is possible as illustrated with a case study.
