| Kaeser Heated Purge (KBD) Dryers are heated regenerative desiccant dryers that produce dewpoints as low as -4°F. Using activated alumina and large, specifically designed desiccant beds, these dryers cycle air through twin towers and alternately drying the air via adsorption and regenerating the "wet" desiccant. The KEDs provide lower oepratings costs by reducing the amount of purge air used for regeneration. Using only 7% of compressed air for purge air, KEDs heat the dry air to increase its capacity to hold moisture and regenerate the desiccant. |
