Fast processing is our aim

The quality of our products and their preservation for long-term, reliable system operation is very important to us. Consequently, we continuously work towards improving the quality of our products.

By purchasing a Güntner unit, you have acquired a high-quality product. But if you have any complaints about one of our products, we will handle the warranty notice as quickly as we possibly can. We'll also be happy to answer any questions you may have about the test report and credit memos here.
