R&D and Testing Services

R&D Services

Beside developing our latest technologies in disc stack and centrifugal separation, our R&D facilities in Sweden and Germany offer testing and consultancy services for various industries. For the automotive industry, we offer testing and consultancy of passive solutions and Active Crankcase Ventilation Systems (ACCVS), including air oil separation and valve technologies. Sealing and technical plastic design and validation are also part of our portfolio. 

Our laboratories are fully outfitted with cutting-edge testing and simulation equipment including spectrometers to analyse particle distribution and separation efficiency, rotor dynamic test rigs, test benches to simulate icing or soot sedimentation, and special endurance testing equipment to validate and prove overall product lifespan.
