Perma Pure

Perma Pure

 Perma Pure Perma Pure LLC manufactures components and devices primarily designed to dry and humidify gas streams. Their core technology is Nafion®, a Dupont co-polymer that is highly selective in the removal of water. We manufacture Nafion into tubing of various diameters to optimize the transfer of water through the Nafion. The water moves through the membrane wall and evaporates into the surrounding air or gas in a process called perevaporation. This process is driven by the humidity gradient between the inside and the outside of the tubing. In addition to drying and humidifying, their products can be used as ion exchange membranes and specialty separation membranes that take advantage of the unique properties of Nafion.
