NorrDigi: up to 80% reduction of power losses with next-generation motion control
Saving energy with intelligent power management
Norrhydro’s NorrDigi™ system is a revolution in hydraulic technology. Unlike traditional systems it provides precise motion control without the throttling process that often wastes energy through heat dissipation. As well as incurring high fuel costs, traditional approach requires heavy and expensive cooling systems.
With multi-chamber cylinders and an intelligent digital control system, NorrDigi only consumes the power required at any given moment. In lifting operation, it always optimizes the generated force and minimizes the wasted energy. In lowering motion, most of the potential energy is recovered. The two attached videos describe the performance of Norrdigi system in practise.
