About EFG Turbinenbau
EFG Turbinenbau, based in Feldkirchen, Carinthia, specializes in the design, manufacturing and delivery of hydropower turbines. The portfolio includes Kaplan, Francis, Pelton and diagonal (Deriaz) turbines as well as replacement runners and shut-off devices. Runners are developed using CAD/CAM and machined in the company's own CNC machining center from fully forged material, ensuring porosity-free quality and high dimensional accuracy. A CNC milling and turning machining center enables the machining of workpieces up to 2.6 meters in diameter and 8 tonnes in weight. In addition to new installations, the company offers refurbishment and revitalization, engineering with hydraulic design, testing and inspection, assembly, commissioning as well as maintenance and spare parts supply. Customers include private power producers, cooperatives, municipalities, municipal utilities and energy supply companies at home and abroad.
