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

- 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

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

- 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 safety

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