April 6, 2026

City Capital Advisors, a Chicago-based middle market investment bank, is pleased to announce that it acted as the exclusive financial advisor to Mechanical Solutions, Inc in the sale of the company to Universal Plant Services, a portfolio company of New State Capital Partners.

Universal Plant Services (“UPS”), specialists in rotating and reciprocating equipment services, announced that it has acquired Mechanical Solutions Inc (“MSI” or the “Company”), an engineering firm focused on fluid machinery and turbomachinery systems. UPS is a portfolio company of New State Capital Partners, a middle market private equity firm with over a decade of experience partnering with entrepreneurial management teams. Terms of the transaction were not disclosed.

“The addition of MSI significantly expands UPS’s capabilities and strengthens our ability to support our customers’ most critical assets,” said Eric Zimmer, CEO of UPS. “By combining MSI’s advanced engineering, diagnostics, and analytical expertise with UPS’s industry‑leading field services, maintenance, and outage execution, we are well positioned to deliver a more powerful, end‑to‑end solution.”

The combined UPS–MSI platform eliminates the traditional gap between engineering analysis and operational execution by integrating diagnostics with field execution capabilities. Based in Whippany, New Jersey, MSI tests, analyzes, and solves complex vibration, dynamics, and performance problems in critical rotating machinery including pumps, compressors, and related equipment. Operating for more than 30 years, MSI offers field-based troubleshooting, advanced analysis, and design assessment services to industrial sectors including petroleum refining, electric power generation, chemical processing, and water and wastewater utilities.

“We are very excited to join UPS,” said Bill Marscher, CEO of MSI. “We see a clear strategic fit with UPS as a market leader in rotating equipment services and are confident in the cultural compatibility with UPS, which shares MSI’s unwavering commitment to safety, service quality, and customer support. We look forward to supporting our customers as part of a larger organization with additional resources and a broader suite of technical capabilities.”

“We invested in UPS as a buy-and-build platform and are thrilled to support management with this first acquisition in our partnership together. With MSI, UPS adds key technical capabilities that build on UPS’s differentiation in the market” said Will Swayne, Senior Principal at New State Capital Partners. “We look forward to continuing to support Eric and his team in this next phase of growth.”

Thomas Haan, Operating Director at City Capital Advisors and Principal of Global Equity Consulting, said “MSI is a great strategic fit enabling UPS to extend its scope of capabilities to include high level engineering analysis that improves mission-critical equipment reliability in key industrial sectors.”

Barry Craig, Managing Director at City Capital Advisors, said “We are very glad to have had the opportunity to represent MSI in this transaction that creates a new chapter for MSI to continue its growth with the additional resources available as part of a larger organization.”
