Have you ordered your spare part but aren’t quite sure how to fit it? No problem. Make use of our repair service – by telephone, at your premises or at our repair department in Haan. Our service engineers will be happy to visit you to fit the spare part. Naturally, we aim to carry out every repair as quickly as possible.
System downtime is our top priority, so that we can get your production up and running again quickly.
If an on-site repair isn’t possible or would be too time-consuming, our well-equipped repair department, staffed by experienced technicians, is at your disposal. This Service is often used, for example, in the case of faulty motors or unbalance weights, as our customers usually don’t have the necessary lifting equipment.
Training and professional development for our service engineers
Expert support through regular training
As the inventor of mass finishing – known as ‘Trowalising’ – Walther Trowal has always been synonymous with comprehensive expertise in mechanical engineering. Through ongoing training and safety briefings, we ensure that our service engineers apply this knowledge safely and competently in practice at your premises.

Our experts will work with you to find the right solution for your specific application. Please feel free to contact us directly or use the online enquiry form.
