Alumina Desiccants

Alumina Desiccants

​Zibo Xiangrun and Shandong Bairui offer high quality XR101 Activated Alumina Desiccant for the absorption of water vapor and other gases from compressed air.
Activated Alumina Desiccant is available in 1/8-inch, 3/16-inch and 1/4-inch bead sizes. We can typically ship 25kg bags, 150kg drums or bulk bags of Activated Alumina the day after we receive your order. Dew points to -40°F and lower may be achieved with Activated Alumina Desiccant depending on the compressed air dryer design and operating conditions. The 1/8-inch (2-5mm) Activated Alumina bead is the size most frequently used in regenerative dryers.alumina-desiccants Activated Alumina Desiccant is highly porous with a large surface area, which will not weaken or break when subjected to high liquid concentrations. High crush strength and strong, durable shipping bags, allow for easy transport.

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

Use

Activated alumina desiccant is used for deep drying of gas or liquid    phase of petrochemicals, air separation adsorption and adsorption drying by    automatic instruments


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.
