The use of desiccant humidity control systems in industry has made the manufacturing of everyday products -- from life saving pharmaceuticals to candies and from windshield safety glass to contact lenses -- more reliable and profitable for cost conscious producers and more economical for value driven consumers.

Now humidity control in commercial and institutional buildings and homes can improve indoor environmental quality (IEQ).  The use of desiccant-based enthalpy exchanges and/or dehumidification equipment offer the following potential benefits:

  • Improved indoor air quality

  • More productive working/comfortable living conditions

  • Reduced moisture damage and remodeling/redecorating costs

  • Reduced energy costs

  • Reduced peak demands on electric utilities

  • Natural gas load shifting to summer months

  • Reduced global warming gas emissions

To learn more about desiccant technology and its applications, visit the websites on the links webpage.

To spread information about these desiccant systems and to broaden and accelerate their deployment, the U.S. Department of Energy has constructed a mobile exhibit featuring the advantages of desiccant humidity control (DHC Van).  It provides a first-hand experience of the comfortable aspects of active humidity control with desiccant systems.  The DHC Van is available for display and demonstration at national, regional, and local meetings of trade associations, professional societies, and utility groups.  This website provides answers to many of the frequently asked questions about hosting the DHC Van and facilitates communications with the potential host organizations.
