Gas Dryers handle flows up to 1 lpm.
November 8, 2005 -
Designed to dry hot, wet, sample gases prior to analysis, MDH(TM) Series combines heating element with Nafion® technology, which selectively removes only water from sample gases, leaving rest of gas sample unaffected. Dryers remove water directly from vapor phase, preventing loss of water-soluble gases through dissolution in condensate. Units can dry gases with as much as 30% water by volume and use built-in thermostat to prevent condensation throughout drying process.

Perma Pure Introduces Heated MDH(TM)-Series Gas Dryers
Toms River, NJ (October 21, 2005) - Perma Pure LLC, a leader in gas conditioning introduces the heated MDH(TM)-Series dryers. These compact units combine Nafion® technology with a heating element to dry hot, wet, sample gases prior to analysis, increasing sample accuracy and reducing damage to downstream analysis equipment.
The heated MDH-Series gas dryers were specifically created to dry gas samples with dew points higher than ambient temperature, without requiring additional heating or insulation. Proprietary Nafion technology selectively removes only water from samples gases, leaving the rest of the gas sample unaffected. Unlike chillers and condensers, Perma Pure's MDH dryers remove water directly from the vapor phase, preventing the loss of water-soluble gasses through dissolution in condensate.
Designed to handle gas flows of up to 1 lpm, the heated MDH-Series gas dryers can dry gases with as much as 30% water by volume. To prevent condensation, the built in thermostat controls temperature throughout the drying process. The sample inlet and the first part of the dryer are heated, keeping the gas hot until the water is removed. As the gas dries, it also cools, exiting the dryer with a low dewpoint at ambient temperature. Only electrical power and dry purge air are needed for operation.
The compact design can be incorporated easily into analyzer cabinets or used as a stand-alone device. The dryers are available for use with 110 VAC, or 12 VDC.
