Holset, a leading producer of turbochargers, was incorporated in 1952. It was established by Paul Croset and Brian Holmes as a fully-owned subsidiary of B.H.D. Engineers Limited of England. After two decades, in 1973, Holset was acquired by Cummins. The company changed to its current name, Cummins Turbo Technologies, in 2006. Cummins Turbo Technologies is headquartered in two locations: Tennessee, the United States and Huddersfield, England. The company has six manufacturing facilities in different locations including the USA, United Kingdom, India and China.
In addition to supplying turbochargers for Cummins engines, the brand provides turbos for Volvo and Detroit Diesel engines. The line of turbos currently offered by Holset is the X-Range series. The two significant models under the series include: the HX20, which is suitable for engines that have a displacement of up to four liters, and the HX83, which is compatible with engines that have a displacement of up to twenty five liters.
Holset initially manufactured vibration dampers and couplings for heavy-duty automobiles. In the late 1950s, the firm entered into an agreement with the Schwitzer company to manufacture turbochargers for the European auto industry. In 1965, the brand manufactured the Model 3LD, the first turbocharger without a nozzle ring. The 'H' family of turbos was released in 1973. In the same year, Holset spun off its millionth turbocharger. The 1970s saw innovative improvements in the development of turbochargers including the introduction of a high speed turbine dynamometer and the first ‘backswept’ compressor design.
Holset turbos entered motorsports in 1983, when a car equipped with the brand's turbo triumphed at the Indy Race Car Championship. In the same year, the company started sponsoring turbos for Formula One. In 1986, the brand started producing turbos with Map Width Enhancement (MWE) technology that increased the range of the compressor by 20%. The 'H' line of turbos was replaced by the 'HX' family of turbochargers in 1987. In 1990, Holset along with Scania released the first commercially available turbo-compound engine. This innovation was widely appreciated and helped the brand emerge as an integral player in the turbo industry.
The Holset VGT™, the first turbo with sliding wall variable geometry, was launched in 1998. This experimental design fetched Holset the Queen’s Award for International Trade and Innovation. In 2007, the axial turbo-compound was offered for the Daimler DD15 engine, and it reduced emissions while providing improved power. A line of turbochargers that can be fitted to engines with displacement in the range of two to four liters came off Holset's assembly line in 2010.
Cummins Turbo Technologies' turbos are designed to provide improved fuel economy and engine power. The brand's turbos are manufactured using pioneering technologies to ensure outstanding quality and durability. The company is striving to enhance its techniques to match the requirements of the future market.
