General description
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 counter-flowed 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.
