These compact and portable gas dryers remove only water vapour from a gas stream, leaving other components unaffected
DM-Series gas dryers from Perma Pure combine the selectivity of Nafion gas dryers with the simplicity of desiccant canister dryers.
No pumps or purge gases are required, and they can remove water vapour from a flowing gas stream for hours.
They can be recharged in moments by simply replacing the desiccant and can be reused repeatedly.
DM-Series gas dryers dry continuously with no moving parts, and no electricity is required for drying.
They are extremely corrosion resistant and can process almost any gas.
The gaseous sample flowing through the dryer comes in contact only with Nafion tubing.
This very selectively absorbs water vapour from the gas while quantitatively retaining the remaining sample components in the gas stream.
With Nafion dryers, water vapour passes through the Nafion tubing wall and is carried away by a dry purge gas.
In DM-Series gas dryers, desiccant packed around the tubing provides a dry purge environment.
No power or other utilities are required.
Two DM-Series gas dryer models are available.
The DM-060-24 contains approximately 70 grams of molecular sieve and accepts a flow rate of up to 500ml/min.
The DM-110-24, containing approximately 150 grams of molecular sieve, is best suited for flows of up to one litre per minute.
