Physical Water Treatment -
How it Works by Dr. Ing. H. Jühnke
The devices cause that calcium hydrogen carbonate Ca(HCO3)2 turns out as calcium carbonate (CaCO3) which is electrically and chemically neutral in water. The CaCO3-crystals are special because they do not crystallize as sticky-structured crystals but form a smooth structure. Link

Physiological Institute:
University of Munich Germany
The system Vulcan 5000 was installed at the end of March 1996 in the coolant inflow of the crypton gasion laser Innova 90-K. During the test period the laser was in operation approx. 200 hours. On December 12th 1996 Coherent GmbH checked the laser tubes for lime deposits on the ceramic surface. No lime deposits were detected. Link |

Steinbeis Institute:
Center for Environmental chemistry
The test showed that the tendency to form lime deposits is reduced considerably by the Vulcan 5000 water treatment. In addition, the effect continues for some days after Vulcan has been switched off. The effect is not only limited to a certain part of the pipe, but also passed into the water and to the whole piping system. Link |

User Study - Vulcan in Cooling Towers in Japan
After installation of the Vulcan unit, the statuses of the cooling towers A, B, and C were inspected without using any water treatment chemicals. Even after elapse of approximately six months, almost no scale buildups were observed inside the refrigerators and the heat exchanger tubes, and no water pollution warning was displayed. Link |

User Study: Vulcan in Grease Traps, Japan
The treatment water is effective against rusts and scale on the primary side of the water supply pipe. When service water is used and drained on the secondary side, sliminess or clogging in the drain is reduced, preventing the build-up of metallic soaps in the grease trap. This results in the reduction of the problems of molds or stenches likely to accompany drainage. Link

Rob Branson -Western Australia
I noticed a huge difference after just 1 month. The CWT system is also well priced and simple to install. Because it carefully dissolves the scale, my irrigation system is virtually maintenance free and there's no need to change the filters. This saves me an enormous amount of time and energy. Link |

Lance Butcher -Western Australia
Within three months of installing the CWT water treatment system the iron residual and sludge disappeared. I was staggered by the results. The pipe was completely clear and there were no signs of the iron scale at all.
A reliable and clean sprinkler system is very important for us to maintain a healthy garden. The CWT system has saved me an enormous amount of time and money and I’m no longer cleaning sprinkler heads or replacing the solenoids in the reticulation system. Link

Mrs. Weigt - Potsdam
With curiosity I kept an eye on the water and I was amazed to see the positive difference. I have noticed that my hair feels softer after washing it without using any additional hair cosmetics. Also the shower screen and the bathroom fixtures were easier to clean with much less cleaning agents. Link |

Family Wiechmann - Adelshofen
We have after two weeks already found many of the statements in your product description to be impressively true. The inspection of the aerator after four weeks shows no accumulation of scale, in the past it was necessary to clean it every 4-6 weeks. Link

Mrs. Fuchs - Brieselang
The mentioned changes occured immediately after the installation: the laundry is noticeably softer even without the use of fabric softener, our skin is no longer irritated after washing; there are certainly less limescale deposits on the tiling, the taps and shower partitions. Link |

Mr. Hanebuth - Isernhagen
My wife is very happy with how quick it is now to clean the bath fixtures - and we have five baths after all. I am convinced, too, that the washing machine, the water heater, as well as smaller electrical appliances benefit from the device and consequently use less electricity. Link |

Wolfies Waterfront Grill - Indiana, USA
I want to let you know how satisfied I am with the results using Vulcan 5000 in my restaurant. The Vulcan immediately solved a problem with our restroom water fixtures. The Vulcan eliminated our water softener, along with the required salt and water consumption. The Vulcan drastically reduced our dishwasher soap usage. With this environmentally friendly product, the above savings resulted in a return on investment within 6 months. Link |

Hotel Cadolzburg - Germany
I was even a bit sceptical when I saw your simple equipment and watched how your employee installed it in a couple of minutes and without tools on our incoming pipe. After a few days we already noticed an improvement of the lime deposits. In places where before you had to remove the lime stains with cleaning agents, now there is just a powdery, easily removable "layer of chalk". Link |

Mercure Hotel - Germany
We are pleased to inform you that the water treatment unit has been working perfectly and to our full satisfaction ever since its installation in July 1995. Only a short time after that, we observed that we no longer needed acetic or ascorbic acid in order to clean the aerator and shower heads in our hotel. Link |

Design Hotel Q! - Berlin - Germany
The Vulcan unit makes the daily cleaning of our hotel facilities easier and also allows us to save a lot on cleaning agents for it is no longer necessary to use as much of them as we used before. ... the chalk converted by this device no longer settles on fixtures and panes of glass as it usually did before, which enables us to maintain showers and fixtures free of lime-scale without any trouble.

Pilbara Commercial Laundry - Western Australia
We installed the German made CWT Water Treatment System. Immediately we noticed a significant reduction in the build up of calcium. I believe we have quadrupled the life span of our evaporated air conditioner and we haven't had to replace our hot water system for more three years. Link |

Phillip Best Plumbing - Western Australia
I found the CWT water treatments to be very effective in high temperature heating systems such as commercial combustion ovens in restaurants and even in a very high temperature heating system at a local abattoir. There are also huge time savings associated with CWT water systems. Installation time is cut by at least 90% when compared to similar units. The units, which are made in Germany, are also at least 50% cheaper than other units currently on the market. Link |

Exhibition Center Cologne - Germany
A few months ago we installed your Vulcan 1000 water treatment system in our catering services at the Cologne trade fair. After the installation of your water treatment system in our bistros I noticed a clear improvement of the situation. The limescale deposits are now much easier to remove thus easing the workload of the staff. Less detergents are needed and I am extremely satisfied with your device. Link

Gegenbauer Health Care Service - Hospital Germany
We are a facility management company responsible for the maintenance and repairs inside the St. Joseph Hospital in Berlin. Some months ago we have installed the Vulcan S250 in the hospital. We can identify a considerable benefit. For example, there are almost no scale deposits on the 2,500 shower heads to be seen any more. This saves manpower and costs of the exchange of sanitary equipment. Link |

University of California, Davis - USA
The Vulcan system reduces scale build up, changes the nature of the scale that does remain as a powdery type of scale that is much more easily removed than typical flaky scale that etches onto tube bundles, pipe and tank surfaces, faucets, aerators, etc. It changes the "feel" of the water for the better, and results in soaps, shampoos, and detergents being needed in reduced quantities and lathering better. I strongly encourage facilities personnel with water treatment needs who are concerned about the environment, sustainability, costs and safety to give Vulcan a try. Link |

Patches of limescale which could previously only be removed by chemical detergents can now simply be wiped away. What is more, the use of the system has notably reduced the calcification in the electrical heating equipment. Link |
