The Big Bore Experience. The RTS Difference.

Rebuilding Power Heads for Enterprise Engines and More.

RTS performs overhauls for a variety of large engines such as:

  • Enterprise (DeLaval)
  • Dresser Rand – Clark©
  • Dresser Rand – Ingersoll Rand©
  • Dresser Rand – Worthington©
  • GE – AJAX©
  • GE – Cooper Bessemer©
  • GE – Superior©
  • GE – Waukesha©

The Enterprise Engines still used today are a sweet spot for RTS.

Known for their durability in generating energy and driving compressors, these engines still need a good check up every now and then—and rebuilding the power heads correctly is crucial to their performance

RTS is uniquely suited to handle Enterprise Engine head overhaul. With decades of experience in the field, we have a tried-and-true process to bring performance back to a big bore engine. We call it the Big Bore Experience…
