ENERGY EFFICIENCY

A SIMPLE MATTER OF CALCULATION

From the outset, for NORD DRIVESYSTEMS, the decision for energy-saving drive units with energy-efficient motors, almost loss-free gear units and drive electronics with energy-saving functions was not only an economic, but also an ecological decision- because less energy consumption also means less impact on our environment.
