Reliable. Cleaner. Smarter.

Looking for an inspired generator solution? Consider natural gas fuel. While working with natural gas was problematic years ago, new technologies have increased the durability and reliability of these gas gensets. Combine that with the reduced air emissions and smaller carbon footprint and you have a winning solution for many applications.

Award-Winning Technology

Our experience and innovative technological advances in natural gas generators have actually won us back-to-back awards from Frost and Sullivan as “The Natural Gas Generator Company of the Year”. In addition, our 500 kW natural gas generator recently earned a Silver Award from the readers of Consulting-Specifying Engineer magazine.

More About Natural Gas

Due in large part to the increased domestic production and use of natural gas, the United States has become a recognized leader in clean energy. Abundant, affordable natural gas has supported manufacturing growth, improved air quality, and lowered carbon dioxide emissions to levels not seen in decades.
