The Perma Pure Hybrid Sample Gas Cooler

Sample gas coolers condition the sample gas of an analyzing system by passing it through a heat exchanger and cooling it down. Removing any moisture from the gas is a critical step in sample gas conditioning, accomplished by using suitable coolers to lower the gas temperature below the dew point, allowing water to condense. The dew point must be as stable as possible for a repeatable analysis result even when the ambient temperature varies. Sample gas coolers have broad applicability in the cement, petrochemical, steel, power generation, and process industries.

The Perma Pure Baldwin Hybrid Sample Gas Cooler combines the superior performance of Perma Pure’s Nafion™ based drying technology with the functionality of a traditional thermoelectric cooler. Powered by compressed air, this nonelectric cooler achieves dew points lower than 0˚C, helping to prevent problems associated with condensation. The patented mechanical design is ideal for locations with limited or no access to power or other areas where a nonelectric product may be desirable.

Sample Gas Moisture Control

Perma Pure

Sample gas used for analysis in process control operations will often need some conditioning in order to accommodate the input  needs of the analyzer. A common requirement is to maintain a certain moisture content in the gas sample, requiring either addition or removal of moisture from the sample stream.

It is advantageous, even necessary, that any conditioning done to the sample gas have no impact on the component(s) subject to analysis. One technology provides for specific removal or addition of moisture (water) in a simple fashion, with no impact on other sample constituents.

Perma Pure gas sample dryers and humidifiers use Nafion® tubing, with a selectively permeable membrane that permits only the passage of water molecules. By controlling relative vapor pressure around the exterior of the tube, moisture can be drawn from, or added to, the sample gas stream. The simple device employs no moving parts and the vapor pressure differential is easily achieved using shop instrument air or other sources readily available.
