275GL+ w/ESM2 Engine

Breaking New Ground in High Horsepower Applications

For more than 100 years, Waukesha Engine has been committed to evolving engine technologies. Waukesha’s newest generation of the 275GL+ with ESM2 gas engine provides optimum performance in gas compression and other mechanical drive applications. Combining improved power and enhanced efficiency, the 275GL+ with ESM2 meets the constant demanded of today’s oil and gas industry.



Lower Emissions


With the ability to operate on a variety of fuels and load profiles, improved fuel efficiency leads to low unburned methane and CO2 emissions. In addition, lower greenhouse gas emissions and a smaller carbon footprint than competitive engines reduce the effect on the environment.

Improved Operational Efficiencies


A low compression ratio piston design coupled with larger turbochargers and fuel flexibility, allow for higher power ratings. Maximize throughput with the 16-cylinder model, rated at 5,000 hp, and a 12-cylinder model, rated at 3,750 hp.

Advanced Controls


The ESM2 engine controller integrates engine functionality into a single, closed-loop system. Directly monitor and manage air/ fuel ratio control, wastegate control, turbocharger bypass control, ignition timing, and knock detection to make data driven and informed decisions.
