• Creates dry atmosphere in the chamber.
• Consists of an air drier, solenoid valve, flow meter, injection tube, pressure relief vent.
• Heatless Regenerative Desiccant Air Drier.
  • Takes the moisture out of "shop air".
  • Moisture is purged from two dessicant towers on an alternating basis, at 30 second intervals (heatless regenerative process).
• For low controlled humidity in humidity chambers (below 6°C dewpoint limitation of standard humidity range) .
• To eliminate condensation in temperature chambers.
• Higher initial cost compared to GN2 Purge.
