Based in the historic industrial town of Hedemora, Sweden, Hedemora Turbo & Diesel AB operates as a specialized engineering firm deeply rooted in the Scandinavian tradition of heavy machinery manufacturing. The company serves as the original equipment manufacturer for Hedemora diesel engines, a lineage of power units that has been integral to the maritime and naval sectors for decades. While the company’s origins trace back to the early 20th century under the predecessor entity Hedemora Verkstäder, its modern iteration focuses on sustaining the lifecycle of existing power plants and developing efficiency-enhancing turbocharging solutions.
In the maritime domain, the company holds a critical role as the sole authorized provider of genuine spare parts, technical support, and overhaul services for the global Hedemora engine fleet. These engines were widely installed in a variety of marine applications, ranging from merchant vessels and ferries to offshore platforms. Notably, the brand possesses a strong heritage in the naval defense sector, with its engines powering submarines and surface vessels for the Royal Swedish Navy and other international fleets. This specific naval expertise requires the company to maintain rigorous quality standards and deep technical knowledge regarding acoustic signatures and shock resistance, traits often demanded in military marine environments.
Beyond maintaining legacy engines, the company designs and manufactures a proprietary range of turbochargers known for their application in both marine and rail sectors. These turbocharging systems are engineered to improve the performance of medium-speed diesel engines, often serving as retrofit solutions to enhance combustion efficiency and reduce emissions in older vessels. The organization manages the entire production chain, from design and casting to machining and assembly, ensuring that critical components meet precise tolerances. By offering modernization packages, such as control system upgrades and turbocharger retrofits, Hedemora Turbo & Diesel AB enables ship operators to extend the operational life of their equipment while adapting to evolving environmental regulations. The firm functions not merely as a parts supplier but as a technical partner dedicated to the longevity and optimization of heavy-duty marine propulsion and power generation systems.
