Overview

Howden Turbo GmbH is a German engineering company headquartered in Frankenthal, in the state of Rhineland-Palatinate. The company operates in industrial turbomachinery, with products and engineering services centered on steam turbines, turbo compressors, process-gas compressors, and industrial fans. Its equipment is used in applications including power generation, mechanical drive systems, chemical processing, water and wastewater treatment, mining, steelmaking, and cement production. The Howden Turbo identity was established in 2017 after the acquisition of Siemens Turbomachinery Equipment GmbH, commonly abbreviated as STE, by the industrial engineering group associated with Howden and Colfax Corporation. The transaction transferred a long-established Frankenthal engineering operation into the Howden organization. The company was formally established as Howden Turbo GmbH on October 3, 2017, and its business history reaches back through Siemens to the former Kühnle, Kopp & Kausch group. The predecessor business was created in 1899 through the merger of three family companies led by Georg Adam Kühnle, Hans Kopp, and Rudolf Kausch. Under the Kühnle, Kopp & Kausch name, the company developed expertise in turbines, compressors, and related rotating equipment. Its history also included an automotive turbocharging operation. KKK turbochargers became visible in motorsport during the 1970s, including their use in Porsche's Martini-sponsored World Championship-winning 935 racing program. The automotive turbocharger activities were later separated from the industrial business and ultimately became associated with BorgWarner. Ownership changed repeatedly during the late twentieth and early twenty-first centuries. MTU acquired a majority interest in 1983, bringing the business indirectly into the Daimler-Benz group after Daimler-Benz acquired MTU. Penske Corporation acquired a majority stake in 1994, followed by BorgWarner's acquisition of a majority interest in 1997. In 1998, the turbocharging systems division was separated as 3K-Warner Turbosystems, while the remaining Kühnle, Kopp & Kausch activities continued as an industrial engineering business. The Turbo Group and Frankfurt-based private-equity firm ECM acquired the company in 2005. Siemens Power Generation acquired it in 2006, and the company was renamed Siemens Turbomachinery Equipment GmbH in 2007. Within Siemens, the business complemented the power-generation portfolio with industrial steam turbines rated up to approximately five megawatts. Multi-turbine arrangements, including Tridem and Quadriga configurations, could extend the combined capacity to approximately ten megawatts. Its compressor and fan products served a broader range of process and infrastructure applications. In 2015, Siemens announced a plan to relocate turbine production to its Brno facility in the Czech Republic as part of a cost-reduction program. The proposal threatened a substantial reduction in employment at Frankenthal and led to protests and discussions with the works council and IG Metall. Siemens subsequently began seeking a buyer for the complete site. The sale to the Howden organization was announced in 2017 and completed for a reported price of €195 million. Howden Turbo retained the Frankenthal base and was associated with additional locations in Springfield, Missouri; Helsingør, Denmark; and Mornago, Italy. The brand therefore combines a modern Howden corporate identity with more than a century of inherited German turbomachinery engineering history. Its principal market role is as a specialist supplier of engineered rotating equipment for industrial customers rather than as a consumer-facing brand.

History

Howden Turbo's direct corporate history begins in 2017, when Siemens Turbomachinery Equipment GmbH was acquired by the Howden organization associated with Colfax Corporation and renamed Howden Turbo GmbH. Its industrial heritage is considerably older. The predecessor company was formed in 1899 through the combination of three family businesses led by Georg Adam Kühnle, Hans Kopp, and Rudolf Kausch. The resulting Kühnle, Kopp & Kausch business, based in Frankenthal, developed into a German mechanical-engineering company specializing in rotating machinery. During the twentieth century, the business operated across both industrial and automotive turbocharging fields. Its KKK turbocharger name became particularly recognizable in motorsport. A single KKK turbocharger was used in the Martini-sponsored Porsche 935 that won the World Championship in 1976, while later versions of the racing car used twin-turbo arrangements. The automotive turbocharging activities were subsequently separated from the industrial company and were acquired by BorgWarner. In 1998, the turbocharging systems operation was spun out as 3K-Warner Turbosystems, a BorgWarner subsidiary. The industrial Kühnle, Kopp & Kausch business underwent a series of ownership changes. MTU acquired a majority interest in 1983. Following Daimler-Benz's acquisition of MTU, the company became an indirect Daimler-Benz subsidiary. Penske Corporation acquired a majority stake in 1994, and BorgWarner acquired a majority interest in 1997. In March 2005, the Turbo Group and Frankfurt private-equity firm ECM acquired Kühnle, Kopp & Kausch. Siemens Power Generation Group acquired the company in July 2006, with the transaction completed in November of that year. Under Siemens, the business complemented the power-generation division with industrial steam turbines of up to five megawatts. Where several turbines operated together in Tridem or Quadriga arrangements, the combined output could reach approximately ten megawatts. The wider product range included turbo compressors, process-gas compressors, and fans. Turbines served power-generation and mechanical-drive duties; compressors were used in chemical, water, and wastewater applications; and fans were supplied for power plants, mines, steel plants, and cement plants. On June 12, 2007, the company was renamed Siemens Turbomachinery Equipment GmbH. In 2015, Siemens announced plans to move turbine production to Brno in the Czech Republic for cost reasons. The proposal would have affected approximately 210 of the roughly 600 jobs at Frankenthal and triggered strong opposition from employees, the works council, and IG Metall. Siemens subsequently sought a buyer for the complete operation rather than implementing the proposed production reduction as originally announced. The Howden acquisition was announced in 2017. The transaction was reported at €195 million and included the Palatinate factory and related international branches. Howden Turbo GmbH was founded on October 3, 2017, through the acquisition of the Siemens business. The company consequently entered the Howden portfolio with a long-established engineering base, a Frankenthal headquarters, and a product range focused on industrial turbines, compressors, and fans. The brand's history is therefore best understood as a transition from the Kühnle, Kopp & Kausch industrial group, through Siemens Turbomachinery Equipment, into the Howden organization.
