Founded in 2020, Rotera is a company that develops and sells globally active crankcase ventilation systems and solutions for separating liquid and solid particles from aerosols within the automotive industry. Based on s Disc Stack Separation Technology, the active crankcase ventilation system removes oil mist continuously out of the blow-by, thereby enhancing overall engine performance and efficiency. Beside a separation rate close to 100%, the technology generates under-pressure that evacuates the crankcase – a demand by existing and future emission regulations. The system is adapted for car, truck and off-road vehicle engines and can either be electrically driven by a BLDC motor or hydraulically driven using a heron turbine design rates under-pressure that evacuates the crankcase – a demand by existing and future emission regulations.

Rotera is part of the Swedish Grimaldi Industries Group, which develops air cleaning solutions based on disc stack technology.
