Gas Compression
KTA38GC engine for gas compression applications

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.
