HS-AA
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. Activated alumina is manufactured from aluminium hydroxide which is dehydroxylated creating a porous material. 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, HS-AA will release the water molecules that were adsorbed and the material can be reused. Common industries that use activated alumina are:
- Air Dryers
- Drinking Water
- Refineries
- Catalyst Applications
Activated alumina is often altered to increase affinity to select pollutants such as arsenic (HS-AS) and fluoride (HS-F).
