30+6 years

We founded Elchem Water Treatment 6 years ago, and since then we have enjoyed regular success and built up reliable, long-term partnerships.

Elchem Water Treatment Team

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.

Understand and improve.

Understanding existing technology down to the smallest detail and then developing it further and optimising processes. This is how our systems are further developed from year to year. But not without ensuring that existing systems can continue to be operated and are capable of being updated. Longevity is the decisive factor here.
