About us

GRANDESYS was developed as our innovative brand for sustainable use of water. Our company, Schelberger GmbH, is located in the Mödling district outside of Vienna, Austria. The GRANDESYS brand was created three years ago and we've been growing ever since.

With our team of enthusiastic entrepreneurs, we were able to expand GRANDESYS'presence in several EU countries. Our product line has gradually expanded from ABS plastic cisterns and cast aluminum cisterns to welded stainless steel cisterns. We try to make our sustainable product accessible to different customers.

Our office in Mödling is complemented by our warehouse and assembly point southwest of Vienna. We manufacture the metal in the Czech Republic in Luže, southeast of Pardubice.

When expanding our product range, we always strive to grow our customer base. We also have cooperation partners in the United Kingdom, Hungary, Romania, the Czech Republic and Slovakia. Together we can deliver our products with a very high quality and that with excellent delivery times.

We manufacture all of our metal components ourselves and can thus guarantee the highest quality. Additional components such as rubber seals are purchased from the best manufacturers in Germany. Since we are a small company, we take care of our customers. We hope to increase awareness of our product and always make our customers our top priority.
