Dry-O-Lite, the industry-leading deliquescent desiccant, is a chemical drying agent specifically formulated for Van Air single tower compressed air dryers and natural gas Pipeline Dryers. Dry-O-Lite is a dense hygroscopic tablet that adsorbs water vapor from streams of compressed air or gas. The surface of the desiccant tablet dissolves slowly, forming a brine solution which drops from the surface. The tablet continuously dissolves, or deliquesces, until the desiccant is fully consumed.

SP is a leading deliquescent desiccant formulated primarily for the dehydration of natural gas for use in Van Air Pipeline Dryers when the gas temperature is below 90°F. SP is a dense hygroscopic tablet that absorbs water vapor. The surface of the desiccant tablet dissolves slowly, forming a brine solution which drops from the surface. The tablet continuously dissolves, or deliquesces, until the desiccant is fully consumed.

10BF is the most effective deliquescent desiccant from Van Air Systems. Formulated primarily for the dehydration of natural gas for use in Van Air Pipeline Dryers, 10BF is a dense hygroscopic tablet that absorbs water vapor. The surface of the desiccant tablet dissolves slowly, forming a brine solution which drops from the surface. The tablet continuously dissolves, or deliquesces, until the desiccant is fully consumed.

Activated alumina is an aluminum oxide bead with an extremely porous structure and high surface area-to-mass ratio. Activated alumina has a wide variety of applications, including compressed air and gas drying, the adsorption of catalysts in polyethylene and hydrogen peroxide production, and as a selective adsorbent for arsenic, fluoride, and sulfur.

Molecular sieve is highly porous sodium aluminosilicate bead for the adsorption of a wide range of liquids and gases. It has a fixed pore size according to the material specification. Van Air Systems offers molecular sieve with a 4 angstrom pore size. Because of its high comparative cost, molecular sieve is normally used for special process applications. In compressed air and gas drying applications, molecular sieve will deliver pressure dew point to -100°F, depending on dryer design and operating conditions.

Silica gel is a spherical bread consisting of 97% silica and 3% alumina with a highly porous surface and a strong affinity for adsorbing water. Silica gel is also applied as a selective adsorbent for a wide-range of hydrocarbons, C02, siloxanes, sulfur, and many other compounds.

Because silica gel fractures in the presence of liquid water, it is often protected with a pre-bed of activated alumina.
