Based Rotera’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.

Rotera’s laboratory is located in lllertissen in Germany. It is equipped with the latest technology and equipment for development and testing according to the automotive standards. In addition to standard equipment, the laboratory consists of several test rigs that are specially designed for CCV testing. Among others, customized test benches for icing and for measurement of soot deposition.

The team consists of engineers with over 20 years’ experience in the automotive industry and specialized in the field of crankcase ventilation and technical plastics engineering, as well as those with over 50 years’ experience in the field of disc stack separation technology. Our engineers have contributed to some of the greatest innovations in disc stack technology and obtained several crucial patents.
