Colville Group announced that its partner company, Kurz Industrial Solutions (“Kurz”), has acquired Rotating Apparatus Co. (“RAC”), a trusted provider of on-site rotating equipment and apparatus services.

The acquisition reflects Colville’s long-term, value-creation-focused approach to investing—partnering with strong operators and supporting businesses through patient capital, operational resources, and a shared commitment to building durable companies.

Rotating Apparatus has earned a strong reputation for technical expertise, safety, and reliability across industrial and energy end markets. By joining Kurz, RAC gains access to additional resources, a larger customer base, and a broader platform designed to support investment in people, expanded capabilities, and enhanced service to customers—without sacrificing culture or operating discipline.

“At Colville, value creation is about doing the fundamentals well over time—supporting teams, investing in capabilities, and helping our businesses better serve their customers,” said Dan Sanderson, Partner at Colville Group and Chairman of Kurz’s Board of Directors. “Kurz’s partnership with Rotating Apparatus reflects that philosophy and strengthens a platform built for long-term success.”

The acquisition expands Kurz’s customer-site services offering and deepens its ability to deliver reliability-focused solutions that help customers extend asset life and improve operational performance.

Rotating Apparatus will continue to operate under its existing name, with its leadership team remaining in place. Colville and Kurz plan to support the business through continued investment in talent, systems, and operational best practices.

“This partnership provides additional resources to accelerate the value we create for our customers and our team,” said Doug Junion , President of Rotating Apparatus Co. “We’re excited to align with owners who share our long-term mindset.”

The transaction underscores Colville Group’s strategy of building value through long-term ownership, alignment with management teams, and a focus on sustainable growth across its family of businesses.
