Heatless Desiccant Air Dryers (Adzorb Series)

Summits Adzorb Series Heatless Desiccant Air Dryers are twin-tower adsorption drying systems engineered to deliver ultra-low dew point compressed air for critical industrial applications. The dryers operate on Pressure Swing Adsorption (PSA) principle, where moisture is adsorbed by desiccant media in one tower while the second tower undergoes regeneration using dry purge air.

Wet compressed air first passes through multi-stage pre-filtration comprising 5 micron particulate filters and 0.01 micron oil removal filters to eliminate bulk moisture, aerosols, and contaminants before entering the adsorption chamber.

Inside the towers, activated desiccant beds adsorb moisture vapor achieving pressure dew points up to –40°C (optional –70°C). The regeneration cycle diverts a controlled portion of dry air, expands it to atmospheric pressure, and purges accumulated moisture from the saturated desiccant.

The system integrates PLC-based control for precise valve sequencing, alarm management, and maintenance alerts. Moisture indicators provide real-time outlet air quality validation. Oil check apparatus ensures downstream oil content remains within 0.1–0.2 mg/m³.

Energy-saving features include purge economizers and Dew Point Dependent Switching (DDS), capable of reducing purge air consumption by up to 50% under part-load conditions.

The dryers are supplied as skid-mounted packaged units with pre-filter, oil filter, desiccant towers, after-filter, silencers, and auto drain systems, ensuring plug-and-play installation.

Adzorb dryers are ideal for pharmaceuticals, electronics, instrumentation, painting, food processing, PET blowing, and critical pneumatic applications requiring moisture-free compressed air.
