Columbus, Ind.-based Cummins Inc. announced that the sale of its exhaust business to Global Tube, a portfolio company of Wind Point Partners, a private equity firm headquartered in Chicago, has closed.

The sale was announced earlier this year and includes what were formerly Cummins exhaust operations in Stoughton, Arcadia, Black River Falls and Viroqua, all in Wisconsin, and in Scoresby, Australia and Daman, India.

The exhaust business was a small part of Cummins Emission Solutions, which is within the company’s Components operating segment. CES specializes in providing a range of after-treatment solutions and technologies to control emissions in diesel engines. The exhaust business was not a core part of the after-treatment business.

This sale allows CES to place greater emphasis and resources on products that are a critical part of Cummins’ growth strategy. As global emission standards become ever tighter, CES has opportunities for significant growth in developing and deploying after-treatment systems for commercial vehicles.

Terms of the sale were not disclosed.

Cummins Inc. is a corporation of complementary business units that design, manufacture, distribute and service engines and related technologies, including fuel systems, controls, air handling, filtration, emission solutions and electrical power generation systems.
