Waukesha 275GL+ (2,720 - 4,835 BHP)


Representing an advanced generation of high horsepower engines, the 275GL+* excels in all evaluation criteria. A unique combination of robust construction and innovative technology, the 275GL+ lean burn engine delivers excellence in fuel flexibility, efficiency, power output and emissions performance for gas compression, mechanical drive and oilfield power applications.

Maximum fuel flexibility
More power in more unconventional gas applications, including full-load down to 600 Btu/ft3 and operation up to 2300 Btu/ft3.

The power you need when it counts the most
The 275GL+ delivers superior power output and efficiency that directly impact the bottom line. The 16-cylinder model is rated 4835 bhp (3605 kWb), with the 12-cylinder version rated 3625 bhp (2720 kWb).

Fewer greenhouse gases
The 275GL+ and its fuel-efficiency advantage provide low unburned methane—a greenhouse gas that has 21 times the effect of CO2—minimizing its carbon footprint and effect on the environment.

Control systems for quick starts and longer run time
The Engine System Manager (ESM) dramatically reduces onsite setup time and requirements, saving days on commissioning and adding years to engine life.
