Perma Pure PD-Series Gas Dryers

Application

Multitube dryer for high flow and high capacity drying applications. 

Description

Perma Pure PD-Series™ gas dryers are multi-tube Nafion™ tubing gas sample dryers designed for high flow, high performance gas drying applications where having a larger amount of of membrane surface area could improve your drying performance. Multiple tubes are bundled together in parallel to form a high capacity dryer. 

These dryers can be used to dry to -45°C without removing other compounds. 

Applications for PD-Series gas dryers include gas sample conditioning for continuous emissions and process monitoring. In these applications, sample gases flowing through the Nafion™ tubing are dried without removing any of the sample analytes. PD-Series gas driers can also be used in small scale process applications. 

Process applications take advantage of one or more of the unique properties of Nafion™ polymer: highly efficient and selective moisture exchange, ion exchange capabilities, and extreme corrosion resistance.
