Physical water treatment since 1996
Water treatment, without chemicals.
The Merus Ring is clamped onto your pipe and stops the minerals and microorganisms in water from settling. No limescale, no corrosion, no biofilm. No chemicals, no electricity, at almost any temperature.
The Merus principle
A physical answer to a chemical problem
Almost every water carries dissolved minerals, salts and microorganisms. As soon as they settle they form limescale, feed corrosion and grow biofilm. The Merus Ring keeps these substances dissolved and moving, so new deposits do not form and existing ones gradually flush away.
How the ring works
What we solve
Four problems, one ring
One Merus Ring addresses the issues that normally need a cabinet full of different chemicals.
Limescale & scaling
Scale narrows pipes, insulates heat exchangers and shortens the life of every machine that touches water.
Corrosion
Corrosion is the single largest maintenance cost wherever water meets metal.
Biofilm & legionella
Biofilm harbours bacteria such as legionella and accelerates corrosion under deposits.
Algae & biofouling
Algae and biomass clog cooling systems and drive up biocide consumption.
The technology
How the Merus Ring works
The Merus Ring transmits a precise pattern of oscillations into the water. Through interference it shifts the natural frequencies of the dissolved substances, raising their solubility. Limescale, rust and biofilm stay in the water and are carried away instead of settling on your pipes.
Explore the technology- Clamped onto the outside of the pipe, no cutting or downtime
- Works without electricity, magnets or chemicals
- Effective from cold water to well above 300 degrees Celsius
- The effect lasts, the ring works like a recording, not a battery
Where it works
Built for every kind of water
From a single hotel boiler to a refinery cooling loop with kilometres of pipe, the same physical principle scales to the job.
Limescale
Stop scale building up in pipes, boilers and machines.
Cooling water
Control scale, corrosion and biofouling in cooling loops and towers.
Hotels & buildings
Protect drinking water systems from limescale, corrosion and legionella.
Industrial water
Keep process, raw and waste water systems running clean.
Heat exchangers
Reduce fouling and keep heat transfer at design levels.
Marine
Treat fresh and sea water on board ships and offshore.
Agriculture
Better water for livestock, irrigation and aquaculture.
Water softening
A salt free alternative that keeps minerals in the water.
Boilers & steam
Prevent scale and corrosion in boilers and steam generators.
Swimming pools
Clearer water with less algae and fewer chemicals.
Food & beverage
Protect ovens, steamers and process water in production.
Oil & gas
Refinery and process water treatment for hydrocarbons.
Evidence on site
Proven where it matters
More than 15,000 installations across industries and climates. Here is a selection with measured results.
Barnacles / Biofouling in the main Sea Water Inlet
On Royal Boskalis Westminster's dredger MV Waterway (Netherlands), barnacles and mussels fouled the sea water inlet yearly. A 55 cm Merus Ring left the pipe clear after 12 months.
Heat Exchanger Fouling stopped and removed
The fouling in heat exchangers is a commom issue in many companies and the resulting cleaning efforts is a common task.
Protect Pumps from Fouling
Vacuum pumps at a large heavy industry plant in China scaled badly as CO2 was stripped and pH rose. A Merus Ring restored the pump within two months and ended unplanned shutdowns.
Struvite precipitation in wastewater
At the wastewater plant in Kranj, Slovenia, struvite clogged heat exchangers and pipes. A 5 inch Merus Ring ended pipe replacement, leaving only effortless periodic cleaning.
Water Treatment in Fitness Clubs
Merus Rings replace traditional water softeners in fitness clubs, reducing maintenance and costs while preventing limescale in steam generators and shower heads.
Pool in Garden
A 100 m3 private garden pool in Slovenia battled limescale and algae despite chlorine. A 2 1/2 inch Merus Ring HCI Bio dissolved the scale in 4-5 weeks and cut chemical use sharply.
Customer voices
Trusted by operators worldwide
“After 8 months since the last cleaning the condition of the evaporator is very good. All plates are clean, no residues on the surface of the evaporator or condenser.”
Fleet Manager

“Today, the water system is free of problems caused by corrosion or pitting.”
Verified customer
Tour Odeon, Monte Carlo, Monaco
“The first thing I noticed was how much longer it took for my kettle to scale up. The water feels softer, detergent works better, and the filtered tap water even tastes better now.”
