nano D5 HL Heatless Twin Tower Desiccant Air Dryer — 70 to 3000 SCFM, -40°F Dew Point

The nano D5 HL series is a family of heatless twin tower (pressure-swing) desiccant air dryers delivering a consistent -40°F pressure dew point for clean, dry compressed air. Each dryer uses a small stream of expanded dry purge air to regenerate the offline desiccant bed, providing continuous, uninterrupted moisture removal in a simple, reliable, and cost-effective package. Pressure vessels are ASME-coded, dryers are UL/cUL compliant, and every unit is manufactured in the USA. Select your required capacity from 70 to 3000 SCFM above.

The nano D5 HL heatless twin tower desiccant dryer protects your compressed air system by removing water vapor down to a -40°F dew point, preventing rust, frozen lines, and contaminated product. With field-adjustable cycle timing, low pressure drop, ASME-coded pressure vessels, and USA manufacturing, the HL series is a dependable choice for point-of-use and whole-plant drying from 70 to 3000 SCFM.
