3512C (HD) Well Stimulation Engine with Dynamic Gas Blending Kit

Well stimulation operations in the oilfield are complex and demanding. The 3512C (HD) with dynamic gas blending engine for well stimulation operations was specifically developed to lower fuel cost while while meeting the highest standards in performance, durability, reliability, and emissions. Cat engines are backed by the worldwide network of Cat dealers ready to support your operation with technical support, service, parts, and warranty. 3512C (HD) engines, with ratings: 1678-1864 bkW (2250-2500 bhp) @ 1900 rpm meet IMO Tier II, U.S. EPA Marine Tier 2, and U.S. EPA Non-road Tier 2 equivalent emission standards. They are available using U.S. EPA and EU Flexibility, and for other regulated and non-regulated areas.
