Operation consisting in restoring the drying substance that actively adsorbs moisture in the dryer to its water adsorption potential again. In adsorption dryers, this is done using dried compressed air or electric or steam-powered heaters that raise the bed temperature. The regeneration cycle requires the process of equalizing pressures between the dryer columns, removing moisture and cooling the desiccant bed using blowers or vacuum pumps.
