Perma Pure Gas Sample Dryers Selection Guide
Perma Pure offers a wide range of Gas Sample Dryers for your demanding applictions. Perma Pure’s MD Series™ and PD Series™ dryers are the ideal choice for drying gas samples prior to analysis. Using our exclusive Nafion™ technology, Perma Pure dryers can reduce the sample dew point to as low as -45°C without any measurable loss of analytes. The exceptional corrosion resistance of Nafion™ allows for the conditioning of harsh samples, even those rich in acids like HF and HCl. A brief review of each product line is shown below. Select your dryer based on your sample gas flow:
The PD (Polytube Dryer) Series is our multi-tube dryer with multiple Nafion™ tubes in parallel to increase flow capacity and efficiency. A wide range of lengths, tube diameters, and materials is available to cover flow rates up to 40lpm.
MD-R Dryer Series
The MD-R (Monotube Dryer, Rotating) Series is nearly identical to the MD Series with the advantage of rotating purge fitting ends, making it easier to install in your equipment. Like the MD, a wide range of lengths and tube diameters is available to cover the sample gas flow rates up to 4 lpm.
