XR101 activated alumina has been specifically developed for air drying. A smooth aspect of the bead has been designed for improved mechanical properties. Very high attrition resistance and crush strength are combined with high surface area and static adsorption capacity to give activated alumina desiccant the features required for the most demanding and safest drying operating conditions.
XR activated alumina enables even better performance with longer cycles and thus provides direct savings by way of fewer adsorbent bed replacements. Transport, loading, disposal and administrative costs are reduced as well.
The amount of water trapped on a solid at a given relative humidity and temperature depends on its chemical affinity for the solid and the number of available sites for interaction. The capacity of a desiccant for water is expressed normally as the mass of water adsorbed per mass of desiccant.

XR has the capability of optimizing the pore size distribution for a specific adsorbent duty, while retaining high mechanical strength. Chemical species are sometimes used to alter acidity or basicity.
