Activated Alumina

Activated alumina desiccant is an aluminium oxide which is highly porous and exhibits tremendous surface area. It is resistant to thermal shock and abrasion and will not shrink, swell, soften nor disintegrate when immersed in water. The uniformity of bead size prevents gas flow channelling and minimises pressure drop.

PRODUCT APPLICATIONS

Drying - Nearly all gases and liquids can be dried with alumina. Due to the high surface area (350m²/g, activated alumina is an effective adsorbent in such gases as Acetylene, Oxygen, Methane and Oxygen along with fluids such as Benzene, Freon, Hydraulic Oils, Kerosene, transformer and vegetable oils.

Alumina is widely used for pressure swing and heatless dryer systems to produce a continuous supply of dry air with a moisture content of better than -70°C dewpoint.

Acid Removal - Transformer oils, lubricating oils and refrigerants all form degradation acids upon use. Air alumina will remove these corrosive acids thus protecting valuable equipment.
