C15 ACERT™ Hazardous Location Engine

C15 ACERT™ Hazardous Location Engine

Cat C15 ACERT hazardous location engines are the ideal solution for specialized and demanding operations in the oilfield. Engines are hazardous-location certified from the factory to minimize installation design, time, and cost. Decades of field operation and intense research and development allow Cat C15 ACERT hazardous location engines to deliver excellent performance with low operating costs and emissions. Hazardous location engines are certified to operate in potentially explosive environments. Applications powered by C15 ACERT engines include workover rigs, pump skids, nitrogen units, acidizing units, cementing units units, blenders, and hydraulic power units. Cat engines are backed by the worldwide network of Cat dealers ready to support your operation with technical support, service, parts, and warranty. C15 ACERT hazardous location engines, with ratings 400-436 bkW (536-540 bhp) @ 1800-2000 rpm meet IMO Tier II and U.S. EPA Marine Tier 3 equivalent emission standards. They are available using U.S. EPA and EU Flexibility, and for other regulated and non-regulated areas.
