Vapor Phase, Activated Alumina

Hydrosil’s HS-AA is designed for air and gas drying. The activated alumina uses a process called adsorption to dry air and gas. The porous material works as a desiccant which when immersed in a liquid the material will not soften or deteriorate. When heated to approximately 350°F-600°F, the HS-AA will release the water molecules that were adsorbed and the material can be reused.
