Rotera, a company based in Sweden and Germany, continues its legacy as a leader in engineering excellence. Formerly 3nine Automotive, this Swedish-founded innovator specializes in Active Crankcase Ventilation (ACCV) Solutions for trucks, cars, and off-road combustion engines driven by “standard” fuels as well as e-fuels such as hydrogen. At the core of its success is Rotera’s patented Disc Stack Separation Technology, which ensures the highest-performance particle separation.
As part of the Grimaldi Development Group, Rotera benefits from over 120 patents and decades of expertise in Disc Stack and Centrifugal Separation Technologies. Beyond ACCV, Grimaldi Development is pioneering advancements in diverse fields, including Carbon Capture and Storage (CCS), blood pathogen diagnostics, and air purification systems, in collaboration with Sweden’s Royal Institute of Technology (KTH).
Rotera’s cutting-edge R&D centres in Nacka Strand, Sweden, and Illertissen, Germany, house state-of-the-art facilities, including spectrometers for particle analysis, endurance testing equipment, and rotor dynamic test rigs. With a team of engineers boasting over 25 years of automotive expertise, Rotera develops not only ACCV systems but also passive crankcase ventilation systems, oil pans, cam covers with integrated air-oil separation, and other powertrain components. From product design to testing and validation, Rotera delivers solutions that advance engine performance while pushing the boundaries of clean technology.
