KTA19GCSLB Gas Compression Applications

Power 420 - 420 hp
313 - 313 kW

Applications

Oil and Gas Gas Compression

Overview:

Gathering compression applications require power that is reliable, durable and has world class support. It calls for the Cummins KTA19GCSLB – 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 KTA19GCSLB has low maintenance cost, stays emissions compliant and keeps the gas flowing. Every day.

Designed for the gas compression market, the KTA19GCSLB 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 K19 diesel. Common gas unique components on the KTA19GC and KTA38GC lower your operating cost.

Emissions – Simple Lean Burn (SLB) engine out emissions meets current EPA NSPS regulations at 2 gr/hp hr NOx.

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 – Turbocharger design delivers maximum performance and life.

Fuel System – Impco varifuel carburetor provides 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 Programmable Control Ignition Module provides precision control and low maintenance with sealed construction and high-voltage output.

Lubrication System – Deep, full-length, high-capacity oil pan. Combination 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.
