About

RNX Water Systems, S.L. develops and commercialises RNX NERO POWER® for agricultural water treatment.

The company is based in Riola, València, Spain.

What we do

We bring a physical water treatment system to agricultural use: sizing units to irrigation installations, documenting field results, and organising the independent validation those results require.

We are deliberately small. Scientific work is done with universities and research institutions, agronomic work with specialists in the field, and technical work with partners. We coordinate; we do not duplicate expertise that exists elsewhere.

How we work

Our field results are promising and preliminary. We report them with their limitations attached, and we do not describe as established what has not been established.

This is not modesty. Water treatment for agriculture is a field where claims have often outrun evidence, and where a technology is judged by the company its vocabulary keeps. We would rather be checked than believed.

Company structure

RNX Water Systems, S.L. is the operating company for RNX NERO POWER® in agriculture. It was incorporated in 2025 and is majority-owned by Euronix Sistemas, S.L., which previously carried this activity and appears as the affiliation in our 2023 published greenhouse study.

Beyond agriculture

AQUA-RNX, a development-stage system for broader water treatment applications, is not in commercial release. Executive summary on request.
