Product Description
Cat 3512C (HD) engines set the standard in the drilling industry. For many years the 3500 has been the preferred choice by drillers due to their high performance, durability, and reliability in the oilfield while maintaining low emissions.The ideal application for the 3512C (HD) engine is mechanical drive for land drilling rigs.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: 932-1100 bkW (1250-1475 bhp) @ 1200 rpm meet U.S. EPA Non-road Tier 2 equivalent and CARB Tier 2 equivalent emission standards. They are available using U.S. EPA and EU Flexibility, and for other regulated and non-regulated areas.
