KTA38GC Gas Compression Applications Spec Sheet - 1

Gathering and midstream compression requires power that is reliable, durable and has world-class support. It calls for the Cummins KTA38GC – an emissions compliant, high-performance natural gas engine that shares the proven heritage of the Cummins K Series diesel engines and many of the same heavy-duty components. It is no surprise that the KTA38GC has low maintenance cost, stays emissions compliant and keeps the gas flowing. Every day. General Specifications V-12, 4-Cycle, Natural Gas Bore Engine Power* Compression Ratio Aspiration Exhaust Type Watercooled manifold Designed for the gas compression market, the KTA38GC delivers exceptional reliability and low cost of operation. Base Engine – Most major components, including block, crank, cam, gears and liners, are common with the proven K38 diesel. Common gas unique components on the KTA19GC and KTA38GC lower your operating cost. Emissions – Two configurations: Simple Lean-Burn (SLB) or rich burn with catalyst. The SLB engine-out emissions 2 gr/hp-hr NOx . ich burn Coolant Capacity * Rating dependent ** Weight is approximate and varies with options. COMPLIANT CAPABLE – The KTA38GC engine is capable of meeting the SI NSPS regulations from the factory. However, the owner/operator is required to conduct site compliance testing and submit documentation per the EPA SI NSPS requirements. Engines with the “E” designation include a factory-supplied air/fuel ratio controller and a Cummins Emission Solutions Three-Way Catalyst. The KTA38GCSLB engine emits 2.0 gr/hp-hr NOx, 4.0 gr/hp-hr CO, 1.0 gr/hp-hr VOC. This engine does not meet the revised EPA SI NSPS requirements for non-emergency engines and is offered only for use outside the U.S. Air/Fuel Ratio Control – Oxygen sensor-based air/fuel ratio control maintains emissions rate and fuel consumption. Display shows O2, control valve position and fault codes and provides for user input. Air Handling – Twin turbocharger design delivers maximum performance and life. Fuel System – Impco® varifuel carburetors provide stable operation and fuel tracking through all load ranges. Speed Control – Integral-throttle body electronic governor provides precise and stable rpm control under all load conditions. Ignition System – Cummins Gas Compression Ignition Module provides precision control and low maintenance with sealed construction and highvoltage output. Lubrication System – Deep, full-length, highcapacity oil pan. Combine full-flow and bypass oil filters reduce maintenance costs while extending service intervals. Warranty – Cummins one year, unlimited hours. Backed by a worldwide distributor network.
