Dresser Waukesha has added a fourth model to its 275GL Series of gas compression engines. The new 12-cylinder 12V275GL+, like its 16-cylinder counterpart, is a high-performance model with low NOx capability and class-leading power rating.

With its low NOx capability, the new 12V275GL+ meets the current 0.5 g/bhp-hr NOx requirement
for non-attainment areas. Like its 16-cylinder counterpart, the 12V275GL+ model is equipped
with a NOx sensor that directly measures NOx in the exhaust stream enabling real-time, closedloop
control of the air/fuel ratio to assure optimum performance.

The plus (“+”) symbol in the 12V275GL+ name refers to a series of competitive advantages that go
beyond low emissions and include 2% better fuel efficiency along with Waukesha’s well-known
fuel flexibility for maximum performance on a wide variety of fuel gas compositions and quality.

The 12V275GL+ is rated at 3625 bhp at 1000 rpm and delivers the most power in its class,
maximizing gas throughput and customer profits. In addition, the 12V275GL operates at full load
with no derate at higher altitudes than competitive models.
