Whether you’re managing a municipality, safeguarding critical infrastructure or looking to reduce fuel costs, Cleveland Brothers has a solution built to perform. The new Cat DG40-80 small natural gas generators deliver compact, efficient and low-emission electric power, perfect for backup use. Backed by Caterpillar engineering and supported by expert Cleveland Brothers technicians, this EPA-Certified, 40 to 80 kW range provides dependable energy, whenever and wherever you need it.
Power That Works Smarter
The DG40-80 generators were engineered with flexibility in mind. These systems run on both natural gas and propane, giving you the fuel versatility to adapt to different applications and site requirements. And with a highly efficient, turbocharged aftercooled engine, you’ll get dependable power output with optimal fuel consumption—saving you money while reducing your carbon footprint.
Compact Design. Big Performance.
Smaller doesn’t mean less powerful. The DG40-80 gensets are built to deliver serious capability in a footprint that’s approximately 15% smaller than comparable systems. That means easier installation, more space for other equipment and better access for service and maintenance. Whether you're tight on space or planning for expansion, this compact design gives you more flexibility without sacrificing performance.
Save on Energy and Unlock New Revenue Streams
With rising energy costs and demand charges, the DG40-80 range helps you take control of your power strategy. These gensets are ideal for peak shaving, allowing you to offset high utility rates by running on-site generation during periods of peak demand. You can also participate in demand response and capacity markets, turning your generator into a revenue-generating asset—not just a backup plan.
Built for a Cleaner Tomorrow
If you’re working toward sustainability goals or compliance with environmental regulations, the DG40-80 range supports your mission. Running on natural gas significantly reduces NOx, sulfur dioxide and carbon dioxide emissions compared to diesel alternatives. And because these gensets use reliable pipeline gas, there’s no need to worry about fuel deliveries or on-site storage in an emergency.
