Van Air Systems Deliquescent Air Dryers

Van Air is a leading name in deliquescent desiccant dryer technology, providing efficient, affordable solutions to compressed air and gas drying requirements.

D-Series Single Tower Deliquescent Dryers


Easily remove potentially harmful water vapors from your compressed air lines with Van Air’s D-Series of single tower deliquescent air dryers.

As wet compressed air enters the bottom of the tower vessel, it passes up through Dry-O-Lite desiccant. This desiccant acts like a sponge, absorbing the water vapor and slowly dissolving. The water and dissolved desiccant condensate drop to the bottom of the vessel to be drained, and dry compressed air exits through the top of the vessel.

D-Series deliquescent compressed air dryers automatically adjust for a dew point that is about 20° F lower than the air at the vessel inlet. As a result, the dew point is always exactly where it needs to be to meet your particular compressed air product requirements. The dew point can range from 20° F to 63° F.

Condensate liquids should be drained after eight hours of use, and new desiccant should be added several times per year. The rate of desiccant replacement will depend on how frequently or heavily you use your air dryer.

Benefits and Applications of D-Series Deliquescent Dryers

Van Air single tower dryers offer a simple, cost-effective solution to drying your compressed air. With no moving parts or electricity required, these versatile dryers are suitable for use even in hazardous or dirty environments.

D-Series dryers can be installed virtually anywhere indoors or outdoors. They protect against freeze-ups in winter and liquid in summer for year-round efficacy.

These dryers are ideal for a variety of low-pressure applications:

  • Blast rooms
  • Paint booths
  • Sawmills
  • Industrial plant air
  • Landfill gas and digester gas
  • Ready-mix, cement and asphalt plants

PDL Natural Gas Dryers


Van Air’s PDL natural gas dryers offer an easy, durable solution for removing water vapor from natural gases. These dryers work through the use of several stages. They feature no moving parts and require no electricity.

As the wet gas enters the bottom of the vessel, its velocity is reduced. It passes through a pre-bed coated in a desiccant solution that removes mist and droplets of liquid water too small to be separated mechanically. The heavier drops of water easily separate and fall into the liquid storage area at the base of the vessel.

Next, gas travels up through the desiccant. Any remaining liquid water is removed and vapors are significantly reduced, leaving dry natural gas for your application.

PDL dryers are available in several models to meet your specific requirements. The Titus Company can help find the right model PDL natural gas dryer for you.

Benefits and Applications of PDL Natural Gas Dryers

PDL natural gas dryers eliminate hydrate formation and stop freeze-ups. The desiccant and water condensate that accumulates in the claim area will not freeze above -20° F, giving you efficient gas drying capabilities year-round.

These dryers can be used for a variety of applications:

  • Dry fuel gas
  • Natural gas dehydration at wellheads
  • Inhibition of hydrate formation
  • Protection of meters, regulators and other instrumentation
