Global Air Treatment

Gardner Denver DGH Series Heatless Desiccant Dryers were designed to help you meet your goals. Customizable performance technology is integrated into our standard product so it can be tailored to benefit your specific critical compressed air drying application. Now, you have the liberty to personalize the performance of the standard product to adapt to your specific needs.
  • Pressure drop at rated flow is less than 5 psi
  • Standard voltages: Controllers automatically identify and adapt the controller:
    • Basic: 100-120V/1ph/5-60Hz;
    • Standard and Energy Savings controller: 100-240V/1ph/50-60Hz & 12-24 VDC
    • NEMA 4 Standard Feature with Standard and Energy Savings controllers

    Inlet flows are established in accordance with CAGI Standard ADF-200: Dual Stage Regenerative Desiccant Compressed Air Dryers-Methods for Testing and Rating. Conditions for rating dryers are: inlet pressure of 100 psig, inlet temperature saturated at 100°F.

    Average purge flow rate is the amount of purge air used during the regeneration portion of the purge cycle (purge/repressurization valve open) plus the volume of air used to repressurize the tower after the purge/repressurization valve closes averaged over the cycle time. At 100 psig, the average purge rate is: 14.4% (13.7% for regeneration + 0.7% for repressurization) of rated inlet flow for dryers operating on a 10 minute cycle; 15.5% (13.7% for regeneration + 1.8% for repressurization) for dryers on a 4 minute cycle.

    Outlet Flow: To determine flow of air available at outlet of dryer, subtract purge flow from inlet flow.
