Alumina is a type of Activated Alumina bead that’s particularly well-suited to air-drying applications.
[u]iron sand[/u]. They are slightly less absorbent than molecular sieve beads, in contrast they are significantly more robust. Consequently, Activated Alumina can withstand regenerative drying cycles far better. As a result, they have a far longer working-life than other desiccants.
You can also use Activated Alumina in direct contact with liquids, without swelling, dissolving, or turning to powder. Virtually, you can dry all inorganic gases and liquids using these beads. Furthermore, they have excellent crush strength. As a result, they are an excellent solution for tall drying columns, where they need to bear the pressure.
For all of these reasons, Alumina suit well in the compressed-air industry to prevent corrosion in pneumatic doors, machinery and braking systems.
In addition to desiccation, our customers use Alumina for: adsorption of oil vapour from compressed air systems, water de-fluoridisation, mineral oil reconditioning, and absorption of harmful gases.
Regenerative dryers are the typical application of our 3-5mm beads. Likewise our larger 5-7mm beads are commonly used as pre-bed material, which reduces the moisture load of a fluid prior to its exposure to a more refined bed of silica gel or molecular sieve.
