These dryers can be used to dry to -45°C without removing other compounds. Applications for PD-Series gas dryers include gas sample conditioning for continuous emissions and process monitoring. In these applications, sample gases flowing through the Nafion™ tubing are dried without removing any of the sample analytes. PD-Series dryers are also used as moisture exchangers in fuel cell applications. Fuel cell exhaust gases transfer their moisture and heat to the dry inlet gases (primarily hydrogen). Finally, PD-Series gas driers can be used in small scale process applications. Process applications take advantage of one or more of the unique properties of Nafion™ : highly efficient and selective moisture exchange, ion exchange capabilities, and extreme corrosion resistance.Product Features:Flow rates up to 40 l/mOperating temperatures to max. 120° COperating pressures to 45 psi (absolute)Straight or coiled configurationCorrosion resistantStandard dew points to – 25° C, with lower values possible (contact factory)No loss of analytesNo moving partsPrinciple of OperationPD-Series dryers consists of a bundle of 0.030″ O.D. Nafion™ tubes housed within a single large tube shell. Feed gas flows within the Nafion™ tubes while water vapor absorbs into the tubular membrane walls and is removed. Moisture permeating the tubing is carried away by a dry purge gas within the shell that flows counter-current to the feed. Purge gas should be instrument quality air (-40°C dew point) or nitrogen flowing at two to three times the sample flow rate.Intelligent Product Numbering SystemPerma Pure offers the PD-Series dryer with three sizes of Nafion™ tubing and in a variety of lengths and connection types. Choose the size based on your flow rate and dryness requirement and build your PD dryer according to the selection guide and the part number table below:1 – SeriesPD (Polytube Dryer) SeriesPD2 – Number of Tubes50 – 0.030″ Nafion™ Tubes in Parallel50T100 – 0.030″ Nafion™ Tubes in Parallel100T200 – 0.030″ Nafion™ Tubes in Parallel200T18 – 0.070″ Nafion™ Tubes in Parallel07018T60 – 0.060″ Nafion™ Tubes in Parallel06060T3 – Dryer Lengths12″ (120 cm)1224″ (180 cm)2448″ (120 cm)4872″ (180 cm)724 – Housing Materialmolded PP fittings, SS shellMPSmolded PP fittings, rubber shellMPRmolded PVDF fittings, anodized aluminum shellMKAmolded PVDF fittings, stainless steel shellMKSmolded PVDF fittings, rubber shellMKRmolded PVDF fittings, corrugated SS shellMKCmachined stainless steel fittings, anodized aluminum shellMSAmachined stainless steel fittings and shellMSSmachined stainless steel fittings, rubber shellMSRmachined stainless steel fittings, corrugated SS shellMSCdryer element replacement (for two-part fitting)Edryer element replacementE-MRecommended Sample Gas Flow Rates:2-10 lpm: PD-050T Series4-20 lpm: PD-100T Series10-40 lpm: PD-200T SeriesSelect Your Dryer by Flow and Target Dew Point (Moisture Level)PD Gas Sample Dryer Performance CurvesThe Performance curves above are based upon an inlet dew point of 20°C. For conditions higher than ambient temperature, it is assumed that the first half of the dryer will be used to bring the dew point down to ambient. For this reason, read the value of the next shorter dryer. For example, a stream with an initial dew point of 50°C, flowing at 2 slpm a PD-50T-24 should yield an outlet dew point of -6°C, the performance of the 12″ unit.
