drives and drive modules. Staff at the Fiskeby mill are very


pleased with the results, in all aspects. “On top of energy savings,


are built on ABB’s new all- compatible architecture which is designed to provide customers across numerous industries and


applications with unprecedented levels of compatibility, flexibility and ease of use. They are available as single drives, multi-


we have found the new drive was very easy to install and run, with almost plug and play simplicity,” continues Johanson. “We plugged it in and energy consumption dropped by 80 per cent. Reliability and availability, critical parameters for the paper mill, have also been excellent. “We are very positive about this ABB technology and after the success of the first device we have installed the ACS880 on several other pumps, which are producing energy savings as well.


It tasted good, so we ordered more of the same.”


Energy hunting pays off Johanson’s activities as energy engineer include working across the several departments in the mill, and coordinating with suppliers and consultants, to try to find more points for energy improvements and payback. The work has paid off well, he says. “Over the past 10 years we


have reduced the mills’ specific energy consumption per ton produced by 25 per cent. This is an old mill and there are lots of such opportunities. My main task is to identify them and look for new equipment and applications to take advantage of the opportunities.”


Very comfortable with ABB “ABB is our main supplier of this type of equipment and when we had an offer to try the new drive we took it,” concludes Johanson. “When we choose equipment we try to stick to technologies we know we can rely on and that are interchangeable, with the same spare parts. And we want devices that our technicians are familiar with. “This paper mill has something


like 1,000 drives and for simplicity we want to stick with highly reliable equipment with little variety.”
