BETHLEHEM, PA — February 14, 2023 — Rotating Machinery Services, Inc. (RMS) today announced that an agreement has been reached for the acquisition of the fluid catalyst cracking unit (FCCU) Hot Gas Expander product line from Siemens Energy, Inc.

“This acquisition further solidifies RMS’s position as the OEM service provider for the global installed base of FCCU Hot Gas Expanders”, said John Bartos, CEO of RMS. “Dating back to the inception of CONMEC in 1998, RMS’s legacy brand of multi-OEM turbomachinery services, we have been continuously adding to our fleet of served machines. We have been actively servicing and rerating expanders [for more than two decades] and look forward to introducing new customers to RMS’s extensive engineering and service capabilities.”
