Activated Alumina Desiccant is a very porous form of aluminum oxide of high surface area that adsorbs liquids and gases without any change in form. Activated alumina will not soften or disintegrate when immersed in liquids. Activated alumina may be regenerated to its original adsorption efficiency by heating to a temperature between 350-600°F (177-316°C).

Desiccant: Activated alumina as a desiccant, will work by adsorption. The water in the air will stick to the alumina as the air passes through it. The water molecules become trapped so that the air is dried out as it passes through the filter. This process of regenerating the alumina is achieved when the activated alumina desiccant is heated, it will let go of all of the water stored in it, allowing it to be used over and over.

Air and Gas Drying: Nearly all gases and liquids can be dried with our activated alumina. Water removal is often necessary for efficient processing, storage and transportation of fluids. The 3/16” size is normally recommended for vapor phase dehydration applications where pressures drop minimization yet high H 2O adsorptive capacity is desired. The 1/8” and 7 x 14 Tyler mesh sizes are recommended for use in liquid dehydration and other mass transfer limited adsorption applications. our activated alumina is rapidly becoming the industry standard for drying compressed air. Providing long service life with performance at or below dew point specifications, is a ‘peace of mind’ product for both large and small dryers. it is appropriate for use in dehydrating gases in both thermally regenerative (350 to 600°F) and pressure swing (PSA) modes.
