Zibo Xiangrun and Shandong Bairui produce high quality XR101 Activated Alumina used for Desiccant dryers for the absorption of water vapor and other gases from compressed air. We produce alumina balls for HOC, heated and heatless air drying. We supply alumina balls for thermal swing adsorption process, oil filtration, air & gas drying process. To get effective moisture/water adsorption gas result for a long time with regeneration process, please choose our XR101 activated alumina.
activated alumina used for desiccant dryers
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

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.
FAQ
Q: Are you the best one in activated alumina industry?
A: Certainly. It is not our saying, it is the confirmation from our clients and industry.
Q: What time is storage life of activated alumina?
A: Usually, it is about 2 years in good storage. Before using, if the condition permit, please heat them at about 350℃..
