HydroVision Preview: Sneak Peek at the Show Floor

Many exhibitors are already signed up to showcase their products and services in the exhibit hall at HydroVision International 2013 in Denver, Colo. This article provides advance information about some of these companies and what they have to offer.

By Elizabeth Ingram

Although the 2013 HydroVision International event in Denver is not taking place until next July, we believe now is the perfect time to begin providing you with information on some of the companies exhibiting at this largest hydroelectric industry event in the world. This is in part because we recently learned that our event had the honor of receiving not one but two awards from Trade Show Executive magazine.

Trade Show Executive‘s Fastest 50 Awards honor the fastest-growing shows in the trade show industry. HydroVision International 2011 received recognition for net square feet of exhibit space sold and for number of participating exhibitors. In 2011, HydroVision International’s exhibition featured 318 exhibitors showcasing products and services in more than 50 categories, including mechanical and electrical equipment, engineering services, dam safety and civil-related technology and environmental consulting.

Marla Barnes, publisher of PennWell Corporation’s Hydro Group, says, “HydroVision International’s growth reflects the strength of this industry and the commitment of the companies that serve it.” To illustrate some of this strength and commitment, we are providing a random sampling of exhibitors who will feature their products and services at HydroVision International, July 23-26 at the Colorado Convention Center. This is by no means a comprehensive list, but it is a dynamic group that represents a broad cross-section of the hydro industry and may help you plan now to attend this vital industry event.
