DM-Series Desiccant Membrane Dryer

For applications requiring portability, the DM™-Series desiccant membrane dryer is ideal. No pumps or purge gases are required, yet the cigarette pack-sized dryer removes water vapor from a flowing gas stream for hours, leaving other components in the gas stream unaffected. The dryer can be reused repeatedly and can be recharged in minutes by replacing its desiccant.

DM (Desiccant/Membrane) gas dryers combine the selectivity of Nafion® gas dryers with the simplicity of desiccant canister dryers. Gaseous sample flowing through the dryer contacts only Nafion tubing, which very selectively absorbs water vapor from the gas while quantitatively retaining the remaining sample components in the gas stream. Typically water passes through the Nafion tubing wall and is carried away by a dry purge gas; instead, in DM-Series dryers, desiccant packed around the tubing provides a dry purge environment. No power or other utilities are required.
