in water treatment by ingenuity

At JUDO tradition meets innovation

since 1936.

JUDO has been a pioneer in the field of water treatment for over 80 years. The success concept of our family business: investing in the future, being dynamic, looking for new ways – while remaining true to our southern German, called Swabian, roots. We regularly introduce solutions to the international market that have a major impact on our industry.

Our vision:

Water in perfection

As a southern German family owned business, values such as reliability, awareness of tradition and partnership are particularly important to us. You are at the centre of all our actions. Our customer. We have made it our business to ensure your satisfaction. As part of the JUDO family, you benefit from our many years of experience, our deep understanding of the plumbing and HVAC sector and the reliability and know-how of an international, innovative and renowned specialist in water treatment.

Another important factor that defines JUDO as a company is our ingenuity . Just after the company opened, back in 1936, Julius Dopslaff registered his very first patent. Today we look back on a long history of JUDO inventions that have helped shape the development of the water treatment industry worldwide. Our past success has also heightened our vision for the future. Our aim is it to advance the water treatment industry with new products and technologies, increased technical efficiency and optimised user-friendliy solutions.

1023597 – is the number of the first patent granted to JUDO. It protected a “mixing device for different liquids or liquids with gases”. In our words: the vaccination bee.

The beginning of the JUDO’s success story.

Our values: honest, responsible, innovative.

In short: Swabian.

We are a family business – and that is exactly what we promise our employees and society.

Our company follows the highest performance and quality standards. This also applies to our highly trained employees, who with their know-how ensure the best service. As a company, social responsibility is also important to us. Furthermore, openness, reliability and transparency play a decisive role – not only in internal communication but also with you, the client.

We take responsibility – because water is our greatest asset.

Earth’s surface consists of more than 70 percent water. Global water resources add up to around 1.4 billion cubic kilometres. However, most of this is salt water – and only about 2.5 percent is fresh water. Out of that, only about 213,000 cubic kilometres are accessible to humanity. This water can be found in lakes or rivers, for example. This makes drinking water one of the most valuable resources of all. For us, this is reason enough to spend a great deal of time on it. Closely related to this is also the protection of the environment, which is a top priority at every step of JUDO’s business activities.

We are pioneers – always one step ahead with innovations.

Our developments have always not only had a significant impact on our company, but have also helped shape the market. We create room for new ideas through an atmosphere of creative freedom, and we see every criticism as an opportunity to do something better. This is an important aspect that distinguishes and drives us as innovators.
