Van Air Systems' High Performance, Type HPD, is an absorbent deliquescent desiccant engineered
for high quality compressed air in single and sequential tower air dryers.
HPD is a hard tablet formed from hygroscopic materials that attract and hold moisture.
The materials in the compound are non-toxic and are completely soluble in water.
As the desiccant tablet draws water vapor out of the compressed air, the surface of the
tablet slowly dissolves and forms a solution which eventually drops from its surface.
The deliquescent desiccant tablet continues to remove moisture and forms this solution
until the tablet is entirely consumed. When used in a properly sized single or sequential
tower desiccant compressed air dryer, HPD will remove sufficient moisture vapor to establish
a 23% RH in the air line.
HPD is recommended for use where the operating temperature is at or below 80° F. For
applications where the temperature conditions exceed 80° F, a pre-bed of ceramic bead support
is recommended to maximize the efficiency of the absorbent desiccant.
For over six decades, Van Air Systems has been an industry leader in absorbent
desiccant technology. Please contact us today at 1-800-840-9906 or Email Us
