Cat® C175-20 Offers Greatest Power Output of Any
PEORIA, IL - Caterpillar Inc.
today introduced the C175-20 generator set. The
20-cylinder C175 produces the greatest power output of any
single high-speed diesel generator set available on the
market, producing up to 4 MW of power. It requires less
maintenance and provides the highest power density of any
current high-speed generator set.

"The C175-20 represents a true breakthrough in generator set
technology," said Robert Koval, Investors Projects general
manager of Caterpillar Electric Power Division. "Others have
made promises about similar offerings, but the C175 is the
largest high-speed generator on the market, period. And
better yet, it's available today."
The C175-20 package is built on the proven C175 platform,
which has demonstrated its reliability in Cat®
machines and other power generation applications. The C175-20
is built with the same core engine parts as the C175-16,
which has been in use across the globe in a variety of
applications since 2008. Because they're built with the same
basic engine design and to the same engineering targets, the
C175-20 is as reliable and durable as the current C175-16
The high power density of the C175-20 generator set provides
more power from a smaller footprint. A single 4 MW C175-20
represents a 55 percent reduction in footprint when compared
with two 2 MW 3516B generator sets and a 28 percent reduction
when compared with a 4MW
The increased power density is a key benefit for standby
power for large, mission-critical installations, such as data
centers and hospitals. For a data center, using the 4MW
C175-20 can reduce the ancillary equipment required,
particularly when integrated with Cat switchgear, ATS and UPS
products, resulting in a more cost-effective installation.
The larger single unit allows hospitals to carry larger life
safety loads. In addition to large, mission-critical
applications, the C175-20 generator set can be used for peak
shaving/grid stiffening as the sole source of power to remote
communities and as prime power for remote work sites.
Certified to EPA Stationary Emergency Tier 2 emissions
limits, the C175-20 is a sustainable option for power
generation. Cat aftertreatment solutions are available to
further reduce oxides of nitrogen (NOx),
hydrocarbons and particulate matter. It's also biodiesel
compatible, and low fuel consumption versions are
The C175-20 reduces owning and operating costs by extending
maintenance intervals. For prime and continuous power
generator sets, the oil change interval is 600 hours. For
standby generator sets, a three-year oil change interval
option is available. The first major overhaul for the C175-20
will be at 22,000 hours for the 60 Hz units and at 27,000
hours for the 50 Hz units.
The common rail fuel system maintains a high pressure fuel
supply to the injectors, injecting fuel at the correct point
in the ignition cycle. The improved engine breathing allows
for a greater amount of cooler air in and out of the engine.
That precise control of the combustion event combined with
cool, dense air provides more efficient combustion, resulting
in lower fuel consumption. Inlet-regulated cooling provides
better control of oil viscosity, supplying better lubrication
to engine components. The ridged engine wiring harness
protects critical engine circuits from damage, and redundant
control wiring minimizes the impact of electrical faults.
Available with a full range of factory designed and tested
attachments, the C175-20 offers flexible packaging options
for easy installation and optimal performance. To support
this expanded line of generator sets, Cat dealers and
technicians are factory trained to support the C175 generator
sets, switchgear, UPS, and ATS products.
