High-speed diesel generator set with high power output

Caterpillar Inc. has 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 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 generator set.
 
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 3612.
 
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 available.
 
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.
