Overview
TI Fluid Systems is a global automotive supplier whose business centers on thermal management and fluid-handling systems for vehicle manufacturers. The company describes its work as designing and manufacturing systems intended to improve vehicle efficiency, performance and sustainability. Its products serve vehicles with different powertrains, including battery-electric, hybrid and internal-combustion vehicles, and its stated mission is to help customers produce greener vehicles. Its automotive product range covers thermal management, lines and connectors, fuel tank systems, new-energy storage, ADAS cleaning systems and interior components. Thermal-management offerings include refrigerant lines, coolant modules and thermal-loop assemblies for batteries, electronics and motor drives, as well as traditional HVAC and integrated thermal management. Lines and connectors include brake lines, connectors and bundles, multilayer low-permeation plastic tubes, and high-pressure steel tubing. Fuel-system products include lines, tanks, pumps and modules for several fuel and hybrid applications. New-energy offerings include battery enclosures, hydrogen-tank liners, busbar holders and battery-module end plates. The company also promotes industrial applications drawing on its automotive engineering and manufacturing experience. Its industrial technology areas include battery-energy-storage thermal management, fuel-cell cooling and thermal modules, and solutions for commercial, agricultural and construction equipment. The company says its industrial offering also encompasses fluid storage and delivery and electric-vehicle fast-charging solutions. The business traces its roots to Harry Bundy and Company, founded in 1922 in Detroit. Its history includes the Bundy Corporation and subsequent ownership and corporate changes involving TI Group and Smiths Group. TI Automotive Ltd was formed as an independent company in England in 2001, and TI Fluid Systems PLC later listed on the London Stock Exchange in 2017. The company describes itself as a global partner to automakers and reports expanding its electric-mobility innovation capabilities through centers in Europe and Asia. The supplied information does not identify a current parent company, owner, or headquarters.
History
TI Fluid Systems traces its origins to 1922, when Harry Warren Bundy established Harry Bundy and Company in Detroit, Michigan. The company’s early work included a new method of tubemaking: its heritage timeline records Bundy’s 1922 patent application for that method. It also records the company’s first production site on Bellevue Avenue in Detroit and an early contract from Ford Motor Company to supply gas lines for the Model T. These origins established a long-running connection between the business and automotive fluid-carrying components. During the Second World War, Bundy tubing and other components were used in more than 5,000 war applications, according to the company’s heritage account. Examples listed include oil and gas lines, brake lines and brake-lubrication lines used across Allied aircraft, vehicles, landing craft and carriers. In 1976, Bundy common stock was listed on the New York Stock Exchange. In 1988, the Bundy Corporation was acquired by TI Group. The company’s next major corporate transition came in 2001, when TI Automotive Ltd was formed as an independent company in England after emerging from Smiths Group, which had purchased TI Group. TI Fluid Systems PLC subsequently listed on the London Stock Exchange in 2017. The company’s published timeline identifies that listing as a major step in its corporate history. The business has continued to develop products for changing vehicle technologies. In 2018, it won its first high-volume battery-electric-vehicle thermal program. In 2021, Hans Dieltjens succeeded Bill Kozyra as CEO. The company opened its first e-Mobility Innovation Centre in Rastatt, Germany, in 2022, followed in 2023 by three additional centers in Incheon, Korea; Nagoya, Japan; and Jiading, China. The company presents these centers as part of its work on mobility innovation and its broader shift toward thermal solutions for vehicles with electric powertrains. Today, TI Fluid Systems describes itself as a global partner to automakers. Its current portfolio spans thermal management, fluid lines and connectors, fuel tank systems, new-energy storage, ADAS cleaning and vehicle interiors. It also presents industrial applications in areas such as battery-energy-storage thermal management, fuel-cell capabilities, and commercial, agricultural and construction equipment. Its stated mission emphasizes products and technologies intended to enable greener vehicles and a cleaner environment.
