Adsorption drying types

Heat less adsorption dryers: The regeneration is carried out by cold dried air, it is expanded to just over atmospheric pressure, which makes it extremely dry. For this type of regeneration, approximately 15 % of the dried air is used. These dryers are very simple in design, as no heating equipment is required. This results in very low electric power consumption. The size of the drying towers can be kept very small because the drying/regeneration cycle is very short (1-2 minute).
