Deep degreasing – 100% cleaning efficiency with the Universal 81C

A Universal 81C at Duerr Ecoclean's Technology
Center at Filderstadt. The cleaning trials for
Moeller were carried out here.

Since the beginning of the year electrical equipment specialist Moeller at Schrems in Austria has been relying on a Universal 81C cleaning system from Dürr Ecoclean to ensure that a variety of stamped and turned parts are thoroughly degreased.  

The Moeller Group is a leading supplier of systems and components for power distribution and building automation. 12 to 13 tons of steel and non-ferrous heavy metal parts, some of which are galvanized, pass through the Dürr Ecoclean Universal 81C machine during daily production at Schrems. Oil used in manufacturing adheres to the parts and they must therefore be completely degreased before being passed forward to the next process. The Universal 81C uses non halogenated hydrocarbons so that oil and grease are especially effectively removed. Offering a wide variety of process variants for hot and/or cold dip processes and subsequent vapour degreasing, the machine assures reliable and cost efficient cleaning results.   

Originally Moeller used a perchloroethylene based cleaning method at Schrems. However, when the VOC Directive came into effect in the EU, this provided a reason to seek a new system. The most important requirement was to ensure that the degreasing excellence achieved by the existing model would be retained. In addition the new system was to be capable of operating on a 3 shift basis 7 days a week. This meant that a high level of process reliability and minimal maintenance requirements would be absolutely essential. 

So as to demonstrate that the Universal 81C was able to fulfill such demanding requirements in terms of cleaning quality and consistency during constant utilization, almost 5 tons of samples of dirty parts were cleaned at the Ecoclean Technical Center at Filderstadt, watched over by a Moeller representative, over a three day period of continuous operation. The laboratory analysis that followed brought positive results: “The test run showed that the system was 100% able to meet the demands made of it “, was how Erich Zach, Production Manager for Moeller at Schrems, summarized the report. “In the end, the decision went in favour of the Universal 81C because it represents a reliable and cost-effective alternative and it is very easy to operate.”      

It is already foreseeable that, in comparison with the old cleaning system, considerable annual savings can be reached. The new machine has fully convinced Erich Zach and his team, “The process time is longer than it was previously but minimization of maintenance requirements together with much lower costs for supplying fresh solvents and disposing of used ones mean we will be able, in comparison with the old system, to cut auxiliary production material expenditure and maintenance costs by more than 60%.
