Look at these guys:

Personally, I smell a rat. What's unusual is it seems a sophisticated fraud, not targeted at gullible individuals but industrial buyers (who I'd think were smarter!). If they are not outright lying, Cunrad Cruise Lines, Saudi Aramco are both customers.  Pretty successful, eh?

Claim itself looks dodgy to me:


The MERUS Ring is made out of two halves of a treated alloy. The two halves can easily be installed on the outside of a pipe as a collar.
Once the MERUS Ring is installed, it automatically starts to emit different kind of oscillations. As can be seen in the movie, for each problem there is a dedicated oscillation to fight a specific problem. The red oscillation fights rust and corrosion, the black one fights calcium carbonate and other salts, the green one is fighting microbiological problems such as bacteria, algae or bio-fouling.

Oscillations?  Is that what's in style now?  Has 'vibrations' become too obvious?  Oscillations of what?  Air?  Magnetic fields?  The luminous aether?  Don't be impressed and/or worried that major corporations have used this -- they may have tried it once, or agreed to use a free sample on a test vehicle, but never used it again.
