Dryer Nafion, 50 tubes, 24” length, PP fittings, SS shell

Perma Pure PD-Series™ gas dryers are multi-tube Nafion dryers designed for high flow, high performance gas drying applications. These dryers can be used to dry to –45°C without removing other compounds. PD-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 countercurrent 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.
