C15 ACERT™ Tier 4 Interim Engine

Cat C15 ACERT engines are the ideal solution for your demanding operations in the oilfield. Decades of field operation and intense research and development allow Cat C15 ACERT engines to deliver excellent performance with low operating costs while meeting tight environmental requirements. This is an ideal engine for applications that require Tier 4 Interim or EU Stage IIIB emissions certifications in well service applications such as workover rigs, pump skids, nitrogen units, acidizing units, cementing 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 engines, with ratings: 354-433 bkW (354-433 bhp) @ 1800-2100 rpm, meet U.S. EPA Tier 4 Interim, EU Stage IIIB emission standards and are designed to meet U.S. EPA Tier 4 Final, EU Stage IV emission standards. This information about emissions describes the particular rating's emissions technology. For more information about emissions certification, please contact your local Cat dealer.
