Due to our many years of experience, we also carry out repairs on frequency inverters from other manufacturers. Because let’s be honest: The components are the same/similar!

Regular in-house maintenance / cleaning

More often than one might think, it is impurities that cause defects in the unit’s own cooling system or age-related wear and tear, such as the drying out of condensers. The end result is the total loss of the power output stages and the power supply. Therefore, apply: In drive technology, frequency inverters, drives, etc. can be kept in operation for a long time through regular professional maintenance and preventive measures.

After professional cleaning and the replacement of typical wear parts, the appearance of many devices can improve considerably.

Here we show you how you can increase the service life of your drive technology with little effort: Gearbox maintenance

If necessary, it is also possible to rent replacement equipment (if in stock) during preventive maintenance!
