Modular Heatless Desiccant Air Dryers (Pneuzorb Series)

Summits Pneuzorb Series Modular Heatless Air Dryers are compact twin-tower adsorption drying systems engineered to deliver ultra-dry compressed air in space-optimized industrial installations. Designed on Pressure Swing Adsorption (PSA) principle, the modular platform combines high drying performance with low purge consumption and simplified maintenance architecture.

Wet compressed air first passes through pleated borosilicate depth pre-filters that remove bulk moisture and liquid oil, extending desiccant life. Pre-treated air is directed via shuttle valves into one adsorption tower where premium-grade desiccant removes moisture vapor. Simultaneously, the second tower undergoes regeneration using expanded dry purge air.

Stainless steel conical diffusers ensure uniform air distribution through the desiccant bed, maximizing adsorption efficiency at every stage of airflow travel. High crushing strength desiccant with low attrition loss enhances longevity and consistent dew point performance.

Integrated purge economizer technology reduces purge air consumption significantly during partial load operation. The system also incorporates Dew Point Dependent Switching (DDS) enabling demand-based regeneration for additional energy savings.

Moisture indicators provide real-time outlet air quality validation, while optional oil check apparatus measures residual oil content down to 0.1–0.2 mg/m³. Honed cylinders, PTFE guide rings, and U-cup seals in switching valves extend Mean Time Between Maintenance (MTBM).

The modular vertical design reduces footprint, simplifies installation, and enables easy scalability for instrumentation, pharmaceuticals, electronics, painting, and process air applications requiring low dew point compressed air.
