Standard 3A molecular sieve is used for dehydration and can be applied in both PSA and VSA units to remove water. This molecular sieve has a quick mass transfer rate, high mechanical strength, low attrition, and minimizes byproduct formation. Standard 3A is a versatile molecular sieve that has a wide range of applications including those in natural and petroleum gas dehydration, refrigerant drying, and for use in insulated glass.
The uses above are known and common. We regularly encounter people who use this product for humidity control and gas removal. It works at the molecular level to selectively adsorb certain molecules. Typically it is used as a rugged and tough dehydration product. (i.e.. "it removes the part of water that makes it wet")
