PRODUCT DESCRIPTION

XINTAO Activated alumina, is an excellent desiccant for drying a wide variety of liquids and gases. There are many micro-paths, so the specific surface is large. It is also a kind of trace water desiccant and the pole-molecular absorbent, according to the absorbed molecule polarization, the attachment force is strong for water, oxide, acetic acid, alkali ect.

 

It is available in nominal sizes of  1/8”, 3/16” and ¼” spheres.

APPLICATION

Drying. Nearly all gases and liquids can be dried with XINTAO Activated Alumina Desiccants. 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.

 

XINTAO activated alumina desiccants is rapidly becoming the industry standard for drying compressed air. Providing long service life with performance at or below dew point specifications, it is a ‘peace of mind’ product for both large and small dryers.It also is appropriate for use in dehydrating  gases in both thermally regenerative (350 to 600°F) and pressure swing (PSA) modes.
