Caterpillar Introduces C175-16 Diesel Generator Set


PEORIA , Ill. USA – Caterpillar Inc. today announces the introduction of the C175-16 diesel package generator set for standby, prime and continuous applications. The generator set is available worldwide in 60 Hz packages with ratings up to 3.1 MW and 50 Hz packages with ratings up to 3.1 MVA. The Cat® C175-16 generator set package was designed to offer a larger unit rating, higher power density, lower emissions and reduced installation costs. Meeting U.S. EPA Tier 2 requirements, the new generator set addresses current and future needs of the worldwide electric power industry.

Unveiled in 2006, C175 diesel generator sets have successfully completed rigorous field reliability demonstrations in real-world applications spanning the globe. It has achieved more than 100,000 hours of proven reliability across all Caterpillar product lines, with over 60,000 hours in generator set applications. The C175 has been used for applications ranging from distributed generation to prime power for remote communities, industrial processing plants and rock crushing applications.

“Our customers wanted more power in a smaller package,” said Darrin Heflin, Engineering Manager for the C175. “In today’s economic climates, customers expect their generator sets to deliver improved performance and low fuel consumption, while meeting future emissions regulations. Caterpillar’s answer is the C175, designed to provide a reliable, durable, easily serviceable generator set in a single solid package.”

Five key engine systems comprise the Cat C175-16: fuel system, electronics and controls, air system, cooling system and lubrication system. Engineers incorporated significant input from Voice of Customer (VOC) market research into the design of the systems, allowing Caterpillar to deliver a world-class engine to customers seeking standby and prime power application solutions.

The C175-16’s fuel system utilizes a high pressure fuel pump and control valve that deliver multiple precise injections within a single combustion event. This results in lower emissions, improved performance and reduced fuel consumption. Driven by the ADEM™ A4 controller, the C175-16 engine management system provides superior performance, even in the most demanding environments. Both hard-wired control signals and redundant data links offer reliable control and communication between engine systems.

The air system delivers cooler combustion air at the cross-flow cylinder heads, allowing for higher power density and emission reduction. A new generation of turbochargers was designed for the C175, providing a 5 percent efficiency boost and longer life when compared to traditional turbochargers. A newly designed cooling system cools only the parts of the engine that require cooling, resulting in increased efficiency and lower heat rejection. This method of temperature control allows customers to reduce overall operating costs by using smaller radiators.

The lubrication system utilizes Cat® Advanced High Efficiency Oil Filters which provide a higher level of filtration efficiency while maintaining Caterpillar’s superior capacity. By enhancing the lubrication system, the traditional 500 hour oil drain interval has increased to 600 hours. It may be possible to extend even further with the use of Cat S·O·S Services. This will result in reduced maintenance expenditures and downtime.

The company offers worldwide product support, with parts and service available globally through the Caterpillar service and dealer network. In addition, dealer service technicians are trained to service every aspect of Cat® equipment.
