BE™-Series Braided Exchangers from Perma Pure can dry or humidify gas streams by equalizing the moisture level in the gas stream with that of the surrounding atmosphere using Nafion™ polymer membrane tubing technology to transfer the water. In either application, BE Braided Exchangers will act to achieve equilibrium between the gas inside the tubing and the surrounding atmosphere. This is done without loss of analytes and with no power requirements.
- Transfers only water vapor
- Continuously regenerated
- Adjusts to ambient humidity
- No purge gas needed
- Fast response time
- Variety of connectors available
- Excellent corrosion resistance
- Lightweight and portable
Principle of Operation – Drying
In drying applications, BE-Series Braided Exchangers transfer water vapor from a wet gas stream into the surrounding atmosphere. Drying is complete when the sample humidity level is equal to the ambient humidity level. Since drying proceeds as a First Order kinetic reaction, this level can be reached extremely quickly, usually within 100 to 200 milliseconds. This behavior makes the dryer ideal for applications involving a very humid sample at room temperature. Sample humidity can easily be reduced to as low as 10% of its original moisture content with only a short length of Nafion™ tubing.
