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.

Warranty notice

Transparent and fast processing of your warranty notice is a top priority for us. To help with this, we have created a digital warranty claim form where you can provide us with all of the information we need and also upload any relevant images or supporting documents.
