With more than 65 years of experience developing desiccant formulas, Van Air Systems and Van Gas Technologies are the original and leading manufacturers of deliquescent desiccants for drying compressed air and gases. Deliquescent desiccants are a dependable, cost-effective, and energy-free tool for a wide range of drying applications.
Van Air is also a leading source for a variety of adsorbent desiccants, including activated alumina, silica gel, molecular sieve. These desiccants are used in point-of-use applications as well as in regenerative drying applications.

Adsorbent Desiccants
- Capable of dew points of -40°F to -100°F
- Ability to be regenerated in twin tower style dryers
- Point-of-use instrument dryer applications
Single Tower Deliquescent Dryers
Dew points to -100°F
- High adsorption capacity
- Low abrasion for ensuring minimal dusting and a low pressure drop
- Resistant to liquid water slugging
- Uniform bead size minimizes pressure drop and channelling
Molecular Sieve
Established RH of 13%
- More consistent moisture retention from 10% to 100% relative humidity
- Used to produce dew points as low as -100°F
- With a round shape, the Van Air molecular sieve has a higher abrasion resistance and delivers a lower pressure drop than extruded molecular sieves.
Silica Gel
Dew points of -40°F and lower
- High moisture retention capacity under dynamic conditions
- Available in two types, non-indicating and indicating
- Impregnated moisture indicator changes colour from blue to pink when saturated
- High static adsorption (moisture retention) under certain relative humidity conditions
