Centrifugal Gearbox
Nidec DESCH offers three powerful gearbox technologies for centrifuges:
Each design offers specific advantages and is ideally suited to different performance ranges and applications. This enables Nidec DESCH to always provide the optimum, efficient and reliable drive solution for your separation process.
Nidec DESCH operates its own state-of-the-art test rigs, on which every gearbox undergoes a comprehensive test run. At the same time, these test rigs serve as development platforms for new solutions and technical advancements.
This is how we ensure the highest levels of quality, reliability and innovation – for every single gearbox.
