With 50 years’ experience behind us and over 550,000 installations across the globe, we’re the most widely used water conditioning manufacturer in the world. We use catalytic technology to treat water with nothing added and nothing taken away. No harsh chemicals, no waste water, no energy consumed. Our water conditioners respect the environment, your health and your pocket.

Why choose us?

Nothing added, nothing taken away
Our water treatment uses chemistry, not chemicals. We use catalytic technology to exploit the solubility balance of precipitating calcium ions into the bulk solution of the water. Zero salt, zero consumables.

Unrivalled effectiveness
Some use power, others magnets, and some even add small ions to the water in the form of zinc or other organic media to generate calcium precipitation. But our unique ability to bond calcium into a much more insoluble state means our conditioning is more comprehensive and our treatment lasts much longer too.

Precision engineered
Decades of research and development, robust testing and precision engineering with stainless steel make our conditioners the most accredited on the market.

Designed & manufactured in the UK
Our solutions rely on exact science so we design and manufacture everything in the UK, and our quality assurance and testing processes are second to none.

Tested & approved by the US government
Following a recent 18-month intensive study by the USGSA, Fluid Dynamics are proud to be the world’s only water treatment company tested & proven ‘effective’ by the GSA under the US Government’s Green Proving Ground Scheme, as a valid & effective alternative to traditional salt based water softeners.

Built to last, in every sector
Our products are precision engineered with stainless steel and come with a 15 year ‘pro-rata’ warranty, up to 20-year lifespan and a 1-year money-back guarantee.

Zero maintenance: plug & play
With our water conditioners, you can set it and forget it with zero maintenance, consumables, wastewater or power.
