Abstract:
Perma Pure Nafion™-based dryers rely on a clean, dry purge gas to effectively lower sample dew points for industrial gas analysis. In applications such as Continuous Emissions Monitoring Systems (CEMS) and biogas, clean instrument air is often unavailable, forcing reliance on ambient or semi-dry purge gas that reduces dryer efficiency and accelerates analyzer wear. Ultra-dry compressed cylinders provide performance but are costly, impractical in the field, and quickly depleted. To address this, Perma Pure integrates a compact Heatless Dryer upstream of the Hybrid Cooler, lowering purge dew points to ~–50 °C and boosting drying efficiency by up to 30%.
