Model PD Series - Gas Dryers Brochure

Perma Pure PD-Series gas dryers are multi-tube Nafion gas sample dryers designed for high flow, high performance gas drying applications. 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 dryers are also used as moisture exchangers in fuel cell applications. Fuel cell exhaust gases transfer their moisture and heat to the dry inlet gases (primarily hydrogen). Finally, PD-Series gas driers can be used in small scale process applications. Process applications take advantage of one or more of the unique properties of Nafion: highly efficient and selective moisture exchange, ion exchange capabilities, and extreme corrosion resistance.
