SDS – Supplemental Drying System. Infrared analysis of CO and SO2 is very susceptible to moisture interference, as are measurements of low ppm concentrations of NOx and H2S. It is desirable to remove as much moisture as possible. In these applications, installing the SDS downstream of your conditioning system is an effective and less expensive alternative to a complex subzero cooler.
Proven tube-in-shell membrane technology is the basis of the SDS-Series drying system, which selectively removes water vapor from a gas stream. The driving force is the vapor pressure differential between the sample gas and a purge gas counterflowed outside the tubing. This difference drives the reaction, quickly drying the gas stream.
The SDS-Series drying system is designed as an add on to an existing conditioning system. It can also be used as the primary gas drying device, provided the sample is non-condensing at ambient temperature. It is equipped with 4 mounting holes and 1/4” compression gas connection fittings. The inlet gas stream should be non-condensing at ambient conditions. The system requires a purge gas supply of 2 times the sample flow rate.
