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

Cooling Tower Study - Ackuritlabs
During the time of the installation, the green biofilm had begun to recede and gradually disappear. The next visit was about 3 weeks after the installation. At that point,the green biofilm had been further reduced and the scale deposits had begun to separate from the flutes in coin-sized flakes. About a month after installation, the green biofilm had almost completely disappeared from the surfaces in contact with the Vulcan-treated water. 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

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

Spokane School Kitchen - Washington, USA
The steam convection oven has greatly improved since the installation of the Vulcan. The water is injected via the pipe in the centre of the heating coils and a fan inside the coils blows the water through the coils and comes out as steam. The operating temperature of this device is 350F. The white material you see on the coils is a powder coating that is easily removed with a wet cloth. No more chemicals are required to clean the convection oven. Link

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

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

After purchasing the Vulcan, we immediately noticed a difference in the water consistency, which appeared softer on our skin. However, the most profound change was the lack of deposits on all the usual places:the dishes, all faucets and showerheads. What a relief! Finally we just enjoy our water system without having to replace pipes regularly or add vinegar and substances to counteract the mineral build-up. Link

About three weeks after installation, in early January, I heard water running outside. I went to the back of my home and discovered the outside faucet there running at full stream. This faucet did not work at all and now it was running at or near full flow. All because of Vulcan. Just 2 months after installing the Vulcan, I went to take a shower and I noticed the faucet was completely free of calcium and operating like new. Link

Mr. Hanau - Hemmingen
On the first evening after the installation I was pleasantly surprised as I drank a glass of tap water. It has since then tasted cleaner and milder. Link

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, aereators , etc.. I strongly encourage facilities personnel with water treatment needs who are concerned about the environment, sustainability, costs and safety to give Vulcan a try.
