Subsidiaries/Business Units

Cummins Turbo Technologies (formerly Holset)

The Holset Engineering Co. was a British company that produced turbochargers, primarily for diesel and heavy duty applications. The company had its roots in 1948, when W. C. Holmes became interested in Louis Croset's flexible coupler design. The company started when Paul Croset was convinced to start up and manage the venture, which was based in Huddersfield, England. Holset as we know it came into existence in 1952 as a limited corporation, with the name coming from the first half of Holmes and the last half of Croset.

In 1973 the company was purchased by Cummins after briefly being owned by the Hanson Trust, and continued to expand for the next thirty years. Holset now operates facilities in China, India, Brazil, the Netherlands, the United Kingdom and the United States.

In 2006, the division officially changed its name to Cummins Turbo Technologies to be identified more closely with its parent company. The turbocharger products still use the Holset brand name.

Cummins Filtration (formerly Fleetguard)

Cummins Filtration is headquartered in Nashville, Tennessee, USA and operates facilities in nine other countries around the world. The Filtration Business Unit of Cummins produces filtration products for the diesel and gas markets. Products include oil, coolant, and air filters. The division officially changed its name to Cummins Filtration but continues to brand products under the Fleetguard name.

Cummins Emission Solutions (formerly Nelson)

Exhaust and emissions after-treatment company Nelson Industries was purchased in 1999 due to the increasing importance of exhaust after-treatment systems for meeting future emissions standards. The division officially changed its name to Cummins Emission Solutions to be identified more closely with their parent company.
