C7 ACERT™ (Hazardous Location) Well Service Engines

Cat C7 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 C7 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 C7 ACERT engines include pump skids, acidizing units, cementing units, coil tubing units, 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. C7 ACERT hazardous location engines, with ratings 153-172 bkW (205-230 bhp) @ 2200 rpm meet IMO Tier II, U.S. EPA Marine Tier 3, EPA Non-road Tier 3 equivalent and EU Stage IIIA equivalent emission standards. They are available using U.S. EPA and EU Flexibility, and for other regulated and non-regulated areas.

Features

Cat® Hazardous Location Engine

Cat Petroleum Hazardous Location Engines are third-party certified from Caterpillar - Class I Division 2 (NEC 500), - Class I Zone 2 (NEC 505), and - ATEX Directive (94/9/EC) Group II, 3G environments (Zone 2) with Gas Group IIA, Electrical IIC, and Temperature Class T3

Technology

- Electrical harness containing point-to-point wiring without splices in any power/signal wires - Electrical harnesses and connectors are overmolded and are routed through urethane tube for protection against impact and vertical flame propagation. - To meet safety requirements, connectors require the use of a special tool to be disconnected and bear the “do not disconnect while energized” warning. - Optional ATEX and NEC certified 25-foot customer harness - ECU is certified as part of the engine to restricted breathing per EN 60079-15. ECU is protected with a stainless steel guard. - Fuel injector connections at valve cover bases are protected with stainless steel guards

Advanced Digital Engine Management

ADEM A4 engine management system integrates speed control, air/fuel ratio control and ignition/detonation controls into a complete engine management system. control system with integrated digital ignition, engine protection and monitoring

Air System

- Remote aftercooler (REMAC, air-to-air) and separate circuit (water-to-air) aftercooler options available to match any application requirement. - Water-cooled exhaust manifold and turbo maintain ATEXcompliant skin temperature during operation - Air Inlet shut-off enables emergency shut-off for operator

Improved Serviceability

- Front, right, and rear dipsticks - Remote oil and fuel filters - 12V and 24V electronic systems to improve application flexibility
