Van Air Systems PLD 20-2.8-S Deliquescent Gas Dryer

The Van Air Systems PLD 20-2.8-S is a pipeline deliquescent dryer designed for removing moisture from compressed air and natural gas streams in industrial applications. This vertical vessel utilizes deliquescent desiccant tablets to absorb water vapor, preventing corrosion, freezing, and equipment damage in pipelines. Key features include a robust carbon steel construction with ASME certification, ensuring reliability under high-pressure conditions. It is ideal for oil and gas, petrochemical, and manufacturing sectors where dry gas is critical. Advantages over similar products include low maintenance requirements—no electricity or moving parts—resulting in cost savings and simplicity. However, it requires periodic desiccant replacement and effluent drainage management. Drawbacks may include higher operational costs for desiccant and less efficiency in very high humidity environments compared to regenerative dryers. This unit, manufactured in 2012, shows signs of use with some external paint wear and internal desiccant residue, but remains structurally sound. It offers a capacity suitable for medium-flow applications, with easy installation via flanged connections. Overall, it provides effective dew point suppression up to -40°F, enhancing system performance and longevity.
