The industry-standard activated alumina desiccant is used
extensively in compressed air dryers. Our activated alumina
desiccant can be regenerated to its original adsorption capacity by
purging with hot gas at 350° to 600° F. Activated alumina is for
use in both heated desiccant air dryers and heatless / pressure
swing compressed air dryers. Dewpoints of -100° F can be achieved
depending on dryer design and operating conditions. Activated
alumina is an excellent all purpose desiccant for drying compressed
air and most other gases with air dryers.
