Desiccant (Adsorption) Dryers

Water vapour is water in a gaseous form and is removed from compressed air using a dryer. Dryers provide water vapour removal, with their efficiency measured as pressure dewpoint. Typical pressure dewpoints for adsorption dryers are -40ºC or -70ºC, which means for water vapour to condense into a liquid, the air temperature would have to drop below -40ºC or -70ºC respectively.
