About us

Elchem Water Treatment

30+ years

We have carried on a company that has been in existence for 30 years, actively developed it further and, in doing so, built up trusting, long-term partnerships.

Made In Germany

We may carry the label „Made in Germany“, but that is not the decisive factor. What counts for us is proximity to our partner companies, short distances and fast processes.

Reliability

For us, reliability is the key to successful business. From our systems to the selection of our suppliers – we stand for consistency and reliability.

What makes the difference:

Standard water treatment solutions often reach their limits in practice. Either they require too much maintenance to be cost-effective, or the transport and storage of hazardous chemicals is not an option for you. With EWT’s membrane electrolysis system, you get a cost-effective system that produces a high-purity disinfectant directly on-site from ordinary salt.
No long-term storage, no unwanted byproducts, and water that is always clear and hygienically safe.

We know that reality often presents us with complex challenges, and that’s exactly where EWT’s product portfolio comes in. Not a one-size-fits-all solution, but a scalable range of systems and accessories. This way, you’ll always find the right specifications for your project. Our goal is to ensure that you won’t have to worry about your water treatment.

Management

The cooperation between Dierk Stock and Philipp Schäfer at the head of the team is characterised not only by coordinating functions, but also by their active work on practical developments.

Hydrotechnology

Our team at EWT ensures the efficient operation of your system through precise coordination of pressure and flow. We focus on the optimal performance of your electrolysis system.

Electrical engineering

Our electrical engineering experts carefully optimise the performance of your systems, ensure the perfect adjustment of all electrical components and maximise their efficiency and long-term durability.

Innovation

Development of modern control elements and interfaces. Each member of our team contributes their individual expertise and diverse skills for innovation and useability.

From Germany into the world.

Our location in Freigericht, Hesse, is a key factor in our success. Our suppliers are right nearby. This allows us to maintain equally high standards of quality and efficiency. “Made in Germany” is therefore not just a marketing slogan, but a reality we live by. For you as a B2B partner, this means planning reliability, fast response times, and a transparent, crisis-resistant value chain.

Securing the Future Through Responsible Development

For EWT, responsible development means that every new innovation is designed to integrate seamlessly into our existing system architecture. The key term here is backward compatibility, which protects your investment in the long term. Our hardware components and software updates are designed so that even existing systems can be upgraded without any problems. This ensures that your systems remain up-to-date and secure, even as new guidelines and developments emerge. You always receive the latest technology without having to replace what’s already working.

An Outstanding Partnership

For us, industry awards are not an aim in themselves; we are very pleased to receive feedback from our partners, which reassures us that we are doing our part to contribute to a strong industry.
