product-C175-16 Offshore Generator Set
Caterpillar can help you navigate the challenges in the oil and gas industry, including global competition, tightening emission standards, and high productivity demands. The Cat® C175 delivers more reliable power in less space than any other generator set in its class. As efficient as it is powerful, this compact package will make a huge impact on your rig’s performance. The proven success of the 3500 series engines forms the foundation of the Cat C175 diesel engine. Low owning and operating costs, high endurance components, and outstanding serviceability add to the innovations. The Cat Alarm and Protection System integrates with dual ADEM A4 engine control modules to provide redundant engine control, generator set protection, and a simple operator interface. Cat generator sets are backed by the worldwide network of Cat dealers ready to support your operation with technical support, service, parts, and warranty. Cat C175-16 offshore generator set. Ratings: 1833-2660 ekW (2619-3325 kVA) @ 50/60 Hz (1500/1200/1800 rpm). U.S. EPA Marine Tier 2 certified and IMO Tier II emissions compliant.
