After absorbing moisture from compressed air using the adsorbent (activated alumina) in the adsorption tower to produce dry air, moisture is removed from the adsorbent by reducing the pressure in the tower, allowing for regeneration. This "air drying" and "adsorbent regeneration" are alternately repeated using two adsorption towers, achieving continuous and large-scale production of dry air. Additionally, the regeneration of the adsorbent utilizes a portion of the dry air, eliminating the need for a heat source, making it an innovative system that excels in energy efficiency and maintenance.
