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. Engine Design
- Proven reliability and durability - Robust diesel strength design prolongs life and lowers owning and operating costs - Broad operating speed range Cooling System
Air-to-Air Aftercooled (ATAAC) Engine Mounted Transmission Oil Cooler —
Integration with engine cooling system allows ease of installation and a tighter overall engine package Advanced Digital Engine Management
ADEM A3 engine management system integrates speed control, air/fuel ratio control and ignition/detonation controls into a complete engine management system with integrated digital ignition, engine protection and monitoring Custom Packaging
For any petroleum application, trust Caterpillar to meet your exact needs with a factory custom package. Cat® engines, generators, enclosures, controls, radiators, transmissions — anything your project requires — can be custom designed and matched to create a one-of-a kind solution. Custom packages are globally supported and are covered by a one-year warranty after startup. Full Range of Attachments
Large variety of factory-installed engine attachments reduces packaging time Testing
Every engine is full-load tested to ensure proper engine performance Product Support
