Description
Activated alumina A05 is a highly porous, synthetically manufactured form of aluminum oxide (Al₂O₃). It is used primarily as a desiccant to remove moisture from gases and liquids. It’s also used to filter water and to purify gas streams by selectively adsorbing certain molecules.
A05 is inert, non-toxic and can adsorb gases and liquids without changing its form. Even if submersed in liquid it will remain stable and does not degrade or soften. It has a low dust surface, high crush strength, and can withstand temperatures as low as -40°C.
A05 can be reused by heating to a temperature between 177°C to 316°C. This allows for repeated use without loss of performance.
Typical Applications Include:
-
Compressed air drying systems
-
Liquid phase drying
-
Treatment of transformer oils, lubricants, and refrigerants
-
Drying of natural gas and liquefied natural gas (LNG)
With its exceptional thermal and chemical stability, Activated Alumina A05 is well-suited for demanding environments and extreme temperature applications. It remains one of the most cost-effective and reliable solutions for moisture control, particularly in compressed air systems.

How does a desiccant air dryer work?
Twin tower desiccant air dryer working principle
Adsorption dryers are used when the compressed air application requires a pressure dew point below 0°. The regenerative desiccant dryers consist of two pressure vessels. Both vessels are filled with desiccant. One vessel is removing moisture from the compressed air.
Wet air passes directly through the desiccant bed which adsorbs the moisture. When this vessel is saturated with moisture the valves will switch and lead the air to the other standby vessel. During adsorption in the other vessel, the first vessel will be regenerated. It's a cyclic process.
The desiccant medium has a finite capacity for adsorbing moisture before it must be dried out, or regenerated. To do this, the tower containing saturated desiccant medium is depressurized and the accumulated water is driven off.
How this happens depends on the type of dryer.
- Heatless dryers use only compressed air as a purge
- Blower purge dryers use a combination of air from an external blower, heat, and minimal compressed air
- Blower zero purge dryers use a combination of air from an external blower, heat, and zero compressed air
- Heat of compression dryers use the heat of the compression
- Heated purge dryers use heat and small amount of compressed air
Types of desiccants
Depending on the technology and dew point requirement, there is always the best choice of desiccant, sometimes a combination of multiple layers of desiccants used in our designs. In this way, we will ensure required PDP levels and maximized lifetime for desiccant.
