In 1952 Paul Croset and Brian Holmes formed a new company. Brian Holmes thought the company name should be derived from the surnames of HOLmes and CroSET. Then, on March 29, 1952, ‘HOLSET’ was incorporated as a limited company and a wholly owned subsidiary of BHD Engineers Ltd. of England.

Holset Engineering was deeply involved in the design and manufacture of various components of heavy duty motors, such as vibration dampers and couplings. The 1950s saw a rapid increase in turbochargers worldwide with commercial diesel engines, and in 1954 Holset obtained a license from Dr. Alfred Buechi to manufacture his turbocharger design. Around 1957, the Louis Schwitzer company in Indianapolis, Indiana, had developed a small lightweight turbocharger and followed a close partnership and licensing agreement between Holset and Schwitzer. Holset designed and manufactured turbochargers for the European market where Schwitzer had no manufacturing facilities at the time. In 1973 Holset’s one millionth turbocharger rolled off the assembly line.

Today Holset is known as Cummins Turbo Technologies. While the name is relatively new, Holset has been part of the Cummins Engine Company family for over 30 years. Holset is a world leader in turbocharger technology and Holset turbochargers are an important element in the success of the Cummins brand engine worldwide. But Holset brand turbochargers apply to many commercial applications beyond Cummins brand engines and include big names like Volvo, Iveco, Detroit Diesel, and Scania, among others.

Holset engineers are very familiar with racing and performance. There is assistance on the turbocharger used in the Banks “Sidewinder” ground speed record setting truck is just one example.

Holset’s current turbos are the ‘X-Range’ family. From the HX20 for engines up to 4 liters displacement, to the HX83 suitable for engines up to 25 liters, these turbochargers have advanced design features including improved aerodynamics, improved durability, ‘map width improvement’ and sound suppression. Holset also features a patented variable geometry turbine design that they believe will outperform traditional designs in long-term durability. This new variable geometry design is used in the 2007 Dodge-Cummins turbo diesel pickup.

Cummins Turbo Technologies headquarters is in Huddersfield, England, while its United States headquarters is in Memphis, Tennessee. There are six manufacturing buildings located around the world, including the USA. USA, Brazil, UK, China and India. The newest building opened in 2006 in Charleston, South Carolina, with a manufacturing capacity of 200,000 units per year to meet the growing demand for turbochargers in North America.

Holset turbochargers are synonymous with excellence in machine management with turbochargers and air handling systems worldwide. Designed and manufactured by Cummins Turbo Technologies, Holset turbochargers have been the benchmark in turbocharger technology and design in the mid- and high-range diesel engine market for over 60 years. Now, with the introduction of the Holset 200 series, the range includes lightweight range turbochargers that allow us to expand our range from high power and heavy range equipment to the lightweight range diesel engine market.
