SUSTAINABLE MOBILITY FOR THE WORLD OF TOMORROW. THE DRIVING FORCE

sustainable MOBILITY FOR THE WORLD OF TOMORROW REFUdrive systems and components provide the optimum system solutions for all areas where mobile machines must be equipped with energy-efficient and eco-friendly features. REFUdrive drive systems and components: As a simple hybrid drive train, a full hybrid, or a plug-in hybrid As a complex multi-axis machine with many traction drives and auxiliary units As a single unit or in a special overall housing Installed in a control cabinet or for direct assembly in a vehicle with a higher protection category With air cooling (control cabinet or push-through cooling) or liquid cooling (water or oil) REFUdrive thus provides optimum drive concepts for the world of tomorrow: Increase in energy efficiency Conservation of resources Reduction of CO 2 emissions Decrease in noise Extension of operation times Reduction of operating and maintenance costs REFUdrive components withstand even the harshest environmental conditions and help you implement energy-efficient electric mobility solutions for every type of application. All of our units communicate via CAN bus or the fast, synchronous REFUlink, are perfectly tailored to each other, and ensure smooth operation of your diesel-electric system or battery-electric system. Create a modular solution using components from the REFUdrive family: Generator inverters Motor inverters On-board power units / actuators Batteries Battery management systems Chargers Construction machinery Cranes Commercial vehicles Driverless transport Agricultural machinery Municipal vehicles 2
