Best Uses of Activated Alumina in Air Drying Unit

Activated alumina is a powerful all-purpose desiccant that is highly porous and used in multiple industrial applications. It has a high-surface-area and is highly-porous thus having greater adsorption capacity. Being an effective desiccant, activated alumina is used for air-drying units as well. In this article, we will study how activated alumina works for air drying.

Activated alumina for air dryer

Activated alumina balls are used for heated air drying, compressed air drying, van air drying and several other applications that require air drying process for obtaining the efficient end product.

Activated alumina balls will effortlessly achieve the dew point -40°F to -100°F which is required for compressed air and gas drying application. The desiccant air dryer beads (activated alumina balls) are filled in two identical towers of the air dryer unit. Among these two towers, one is used for air-drying and another one for regeneration. The functions of both the towers are interchanged or switched and are controlled by the central unit.

The compressed air is dried in the drying tower by the activated alumina balls. The second the tower which is wet and saturated undergoes regeneration by either a purge of hot air or by dried compressor air.

How is activated alumina the best desiccant for air drying?

With improved and high adsorption capacity, activated alumina desiccants work immaculately for water, moisture and pollutant adsorption from the air. Following are the features that make activated alumina the best desiccant for air drying:

  • Eco-friendly and safe
  • Higher surface area
  • Powerful adsorption capacity
  • Powder-free
  • Reduced abrasion

Activated alumina for gas drying is another important application of this powerful desiccant. It is used for drying gasses such as Acetylene, Air, Ammonia, Argon, CO2, Cl2, Cracked Gas, Ethane, Ethylene, Freon, Furnace Gas, He, H2, HCL, H2S, CH4, N2, O2, Propane, Propylene, SO2, etc.
