Van Air Systems Deliquescent Air Dryers

D Series – Single Tower Deliquescent Dryers

van-air-systems-d-series-dryer

Van Air Systems D-Series Compressed Air Dryers are single tower deliquescent compressed air dryers for stationary applications. D-Series Dryers remove harmful water vapor from compressed air lines. Wet compressed air enters the bottom of the dryer and flows upward through a bed of deliquescent desiccant, which absorbs moisture as it slowly dissolves. Condensate drops to the bottom of the vessel to be drained. Dry compressed air exits the top of the vessel.

When used with Dry-O-Lite desiccant, the D-Series Compressed Air Dryer automatically provides a dew point that is approximately 20°F lower than temperature of the air at the vessel inlet. For example, if the air inlet temperature is 80°F, the D-series Dryer delivers a 60°F dew point. If the air inlet temperature is 50°F, the dryer delivers a 32°F dew point.

Ideal for a wide range of applications, these compressed air dryers protect against freeze-ups in the winter and liquid in the summer. D-Series Compressed Air Dryers may be installed inside or outside, and with a pressure drop less than 1% of the operating pressure, they are ideal for low pressure applications. Also with no moving parts or electrical components, D-Series Compressed Air Dryers can be applied with confidence in dirty and hazardous locations.

PLD Series – Natural Gas Dryers

van-air-systems-pipeline-deliquescent-dryer

As the industry leader in deliquescent desiccant technology, Van Air Systems designed the PLD to be an economical and effective solution for gas dehydration. Operation of the PLD is simple. Wet gas enters the bottom of the vessel where gas velocity is reduced and flow direction is changed. In this area, heavier drops of entrained water are separated and fall into the large capacity claim area. The gas then moves upward through the bed of deliquescent desiccant tablets, which slowly dissolve as they absorb moisture vapor. The water and desiccant solution fall into the claim area to be drained – the brine solution will not freeze above -20ºF. New desiccant tablets are periodically added. At the dryer outlet, the gas is free of liquid water and water vapor is substantially reduced, eliminating the possibility of hydrate formation.

FEATURES & BENEFITS

  • Stop freeze-ups and hydrate formation
  • No power required and no moving parts
  • 10 year vessel warranty
  • Maximum working pressures 280 PSIG to 1450 PSIG
  • Meets pipeline moisture specifications

APPLICATIONS

  • Natural gas dehydration at wellheads
  • Dry fuel gas
  • Inhibit hydrate formation
  • Protect meters, regulators and other instruments
