The advantage of alumina desiccant
●High Mechanical strength
●Our activated aluminas have very high resistance to attrition and crushing. This is a result of our severe production process.
●The low attrition
●The low attrition and high crushing strength are well adapted to their applications.
●Big surface area and bulk density to get more adsorption
● Even particle
Activated alumina in air drying
Nearly all gases and liquids can be dried with activated alumina desiccant. 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 pressure drop minimization yet high H2O 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. XR101 activated alumina is the industry standard for drying compressed air. Providing long service life with performance at or below dew point specifications, XR101 is a 'peace of mind' product for both large and small dryers. XR101 activated alumina desiccant is appropriate for use in dehydrating gases in both thermally regenerative (350 to 600°F) and pressure swing (PSA) modes.

Activated alumina desiccant Regeneration
Activated Alumina can regenerate to its original adsorption efficiency by heating the desiccant to any temperature from 350° to 600°F (177° to 316°C). When the Activated Alumina desiccant is heated as described above, the water stored in it is released, which enables the Activated Alumina filters to be reused over and over again.
