desiccant air dryers heatless adsorption dryers

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.

Summits LC Series Laser Air Dryers are precision-engineered multi-stage compressed air purification systems designed specifically for laser cutting and CNC laser processing applications. The system ensures delivery of ultra-clean, moisture-free, and oil-free compressed air to protect sensitive optical components such as lenses, mirrors, and beam delivery systems from contamination damage. The drying process begins with multi-stage coalescing pre-filtration using 5-micron particulate filters and 0.01-micron oil removal filters to eliminate bulk moisture and liquid oil from incoming compressed air. Pre-treated air then enters twin desiccant adsorption towers where moisture vapor is removed to achieve pressure dew points up to –40°C. Downstream activated carbon towers remove oil vapors to residual levels as low as 0.003 mg/m³, while submicron filters remove particles down to 0.01 micron ensuring ISO 8573-1 compliant air quality. Integrated Auto Vent Systems (AVS) prevent untreated air from reaching laser cutting heads during switching cycles. Moisture indicators enable real-time outlet air validation, while oil check apparatus monitors residual oil content. Energy optimization is achieved through purge economizers that reduce purge air consumption during part-load operation. The skid-mounted packaged design ensures plug-and-play installation in laser cutting air supply networks. LC Series dryers are essential for fiber laser, CO₂ laser, plasma cutting, and precision sheet metal fabrication industries where air purity directly impacts cut quality, optics life, and production accuracy.

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.
