communities use this gas as fuel for a more sustainable
approach to power.
MINES
Many mining operations can increase mine safety and
reduce carbon emissions with coal gas, while others GREENHOUSES
are realizing the benefits of onsite gas power generation Our gas generator sets produce electricity that can be used
to support greenfield site development. onsite or sold to the local grid. They also produce hot water
to heat greenhouses and carbon dioxide to be used as an

MEETING YOUR NEEDS HAS SHAPED OUR HISTORY
We understand what it takes to deliver a successful gas power generation system, and it starts with a core machine designed for
efficiency and reliability. Since the 1920s, our engineers have been blueprinting and building engines for power production. Although
the technology has changed over the years, the philosophy hasn’t: deliver the most reliable power generation at the lowest possible
owning and operating cost. Today, we not only manufacture power generation equipment, we also provide customized project
financing and trade solutions via Cat Financial.
THE COMPLETE SOLUTION
We’re your complete gas solutions partner. From heat recovery systems to exhaust aftertreatment that complies with the world’s most
stringent emission standards, we’re committed to meeting your specific power needs. And with electrical systems such as master
controls and paralleling switchgear, electrical distribution switchgear and uninterruptible power supplies (UPS) that can
meet either UL or IEC requirements, we’re ensuring you have a complete, integrated system.
PRODUCT SUPPORT WORLDWIDE
Your gas power system is supported by our factory trained global network of Cat dealers. With more than 1,600 dealer locations
in 200 countries, your equipment will be ordered, delivered, installed and commissioned in consultation with a local expert. And
our dealers are available for ongoing power generation support. Ask about oil and fuel services, preventive maintenance and
comprehensive customer support agreements.
LOWER LIFE CYCLE COST
With longer maintenance intervals, higher fuel efficiency and competitive repair options, we’re delivering the lowest total owning and
operating costs. When you design your facility within the Cat Application and Installation Guidelines, you can expect generator set
availability up to 94 percent of planned operating hours annually. It all adds up to a strong return on your investment, year after year.
CG260:
HIGH PERFORMANCE WITH
LOW OPERATING COSTS
HIGHLY EFFICIENT
With recent improvements in turbocharging,
system control and optimized pre-chamber spark
plugs, the CG260 gas generator now delivers
electrical efficiencies up to 44.6 percent.
LOWER OPERATING COSTS
Optimized engine components mean the CG260
consumes up to 30 percent less lubricating oil
than competing gas generators, which means
more money stays in your company’s pockets.
GREATER AVAILABILITY
The CG260 utilizes particle free combustion
with chamber plugs for extended maintenance
intervals and improved heat utilization. The CG260
can run on average 200 hours per year longer
than competitive systems.
SYSTEM CONTROL
Control the entire system, not just the engine,
with the Cat Total Electronic Management System.
Control or monitoring of ancillary equipment such
as heat recovery modules, exhaust aftertreatment
and fuel treatment systems becomes seamless.
Features like temperature monitoring for each
cylinder and anti-knock control allow for maximum
power output and the best possible fuel utilization,
even with fluctuating gas composition.
HIGH ALTITUDE AND
AMBIENT PERFORMANCE
The new high-boost, waste-gated A140 turbo
allows the CG260 to operate at full power up
to 45º C (113º F) intake air, and supply stable
transient load response at higher altitudes.
