Unpacking
Perma Pure has made every effort to ship you a high quality product that has been thoroughly
inspected and tested. It has been carefully packed to ensure that it arrives at your facility in good
condition. Even though every effort has been made to prevent damage during the transportation
process, damage can occur by the carrier. This is out of control of Perma Pure and is the
responsibility of the carrier to ensure that your equipment arrives intact and undamaged.
Inspect outside packaging. If there is any visible damage, inform the carrier at the time of
deliver. This inspection is important! Once the package is signed for, responsibility for
any visible damage then transfers to the consignee.
Unpack your equipment. Visually inspect the outside of your equipment for any damage. If
there is any damage, contact the carrier immediately. Generally, a carrier must be notified
within 24 hours of the delivery to make a hidden damage claim.

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.
