Most process plants are in operation over several decades. During this time, of course, parts of the plant and individual components will repeatedly have to be replaced. The necessary work can generally be performed during the scheduled downtimes for servicing and maintenance, and sometimes even while the machines are running.

The situation gets more complicated, however, when a general renovation is on the agenda, involving the comprehensive renewal of measuring technology, distribution and control system, and power supply. But even a complex modernization can be carried out without additional downtimes, as the following example demonstrates. Experience and competence are essential prerequisites, as well as good planning and preparation - in other words, what is needed is a competent partner.

The company Cordenka is the leading manufacturer worldwide of industrial rayon yarn, sold under the brand name Cordenka. The high-strength yarn is used, for example, as reinforcing material in high-performance tires, hoses and composites. As well as manufacturing approximately 32,000 metric tons of yarn a year at the Obernburg site in Germany and the Polish site in Gorzow, about 14,000 tons of fabrics per year are produced for the tire industry.
