Stora Enso, Nymll Mill SwedenPulp pumpingMonth DD, YYYYCustomers needABB package on a test

The mill tested the ABB SynRM motor and drive package by running side-by-side comparisons with another existing 10 years old motor and drive and using a standard Dranetz PX5 power monitor to measure power consumption. Customer benefitsToo good to be true?

25% less energy consumption more than expectedCooler motors less energy and maintenance needsHelps meet energy saving goalsReduced carbon emissionCustomer FeedbackAutomation Engineer

We were very skeptical in the beginning as well. And when we spoke with our process engineer colleagues they said it was impossible to save so much. So we went through the exercise numerous times, and got essentially the same result. Sendy Zigon
