Large Heatless Dryers

Large Heatless Desiccant Dryers

Large heatless desiccant dryers use pressure swing adsorption technology with twin towers to deliver consistent, ultra-dry compressed air for industrial applications. As saturated air flows through one desiccant-filled tower, moisture adheres to the activated alumina bed while the second tower regenerates using a portion of dried purge air. Automatic tower switching ensures continuous operation with pressure dew points as low as -40°F to -100°F.

  • Pressure dew points from -40°F to -100°F
  • Flow capacities from 100 to 3000+ SCFM
  • Twin tower design for continuous operation
  • Activated alumina or molecular sieve desiccant
  • PLC-based controls with NEMA 4X enclosure
  • Pre and post filtration included
  • Optional dew point demand control for energy savings
  • ASME code pressure vessels
