Vulcan – Anti scale System

The German electronic anti-scale    system

Vulcan Descaler Set

The salt-free and chemical-free system protects cooling towers and industrial applications against scale andVulcan without Salt and Chemicals rust

Vulcan’s eco-friendly water treatment technology prevents scale and rust deposits from building up in piping systems and appliances. The Vulcan anti-scale system applies a physical water treatment utilizing a special impulse technology. Electronic impulses change the form of crystallized calcium in the water so that the calcium crystals do not adhere to pipes and surfaces. Vulcan functions exclusively with these electronic impulses – no chemicals or salt are used and it works 100% maintenance-free.

  • The eco-friendly alternative to softeners against scale and rust problems
  • No salt, chemicals or magnetism – no need to cut the pipes
  • Appropriate for pipe diameters from 1/2” to 20″ (10-500 mm)
  • Fully cast in acrylic for optimal quality endurance
  • Easy, do-it-yourself installation without cutting the pipes
  • For all pipe materials – iron, copper, galvanized iron, stainless steel, PVC, plastic, PE-x, compound pipes, etc.

How the Vulcan De-Scaler Protects Your Home or Building

Vulcan in your home or building

Vulcan protects the whole piping system in your house. It cleans old pipes and protects water heaters, washing machines, etc. The bathroom fixtures are protected: filters, shower nozzles and tiles stay cleaner.

Protect your private swimming pool and jacuzzi

Private swimming pools demand constant maintenance and careful monitoring. The circulation pumps process large amounts of water and are sensitive to scaling. Vulcan protects the equipment and pipes and makes cleaning (e.g. waterline, tiles, showers) much easier.
Jacuzzis: The combination of water, circulating air and pressure in a hot tub tremendously enhaScale_Rust_nces scale build-up. Vulcan makes the cleaning of the tub easier and reduces deposits in the pipes and valves. Covers and tiles on the floor or walls will show less hard scale stains.

Water heaters and heat exchangers

When water is heated with oil, gas, electric or solar heating technologies, scale will settle on the heating eleScale_Rust_Private_Heat_Exchanger_Thumbments and heat exchangers. The loss of energy due to the less efficient heat transfer is tremendous. Vulcan helps to reduce the scaling and extends cleaning intervals. Water tanks in the primary and secondary circuit will need less cleaning and the frequency of cleaning periods will be extended.

Vulcan replaces water softeners

Vulcan is the eco-friendly alternative to regular salt-based water softeners. It is not recommended for young children or olScale_Rust_Private_Water_Softener_A_Thumbder people to drink water that has been treated with a salt-based softener. In addition, the use of softeners is polluting the environment.
When installing Vulcan, an old system can easily be circumvented by simply bypassing it.

Vulcan as an addition to water softeners

Vulcan is the eco-friendly alternative to regular salt-based water softeners. However, if you want to keep the softener running due to special reasons, you can save large sums of money when using Vulcan as an aid. The use of Vulcan will decreaScale_Rust_Private_Water_Softener_B_Thumbse the amount of salt that you need to add. This cuts down costs for salt, maintenance intervals will be extended, fewer malfunctions with backwash valves etc.

How does the Vulcan Descaler compare with a water softener?

Salt-based water softeners (so-called ion-exchangers) use salt and chemicals to treat the water. They are installed into the piping system which should only be done by a professional plumber. They exchange the minerals (calcium and magnesium ions) with twice as much sodium (salt) ions. As calcium and magnesium gets deleted, the water is softer afterwards. This way softeners considerably increase the sodium content of the water which can cause considerable health threats and certainly is a threat for the environment.

Burning money: Regular water softeners are not only expensive to purchase but also you will need a specialist to do the installation. Once in place you will have to constantly refill it with salt. Here are the details.

Never-ending maintenance: Maintenance includes the constant refilling with salt, the washing of the granule and the checking of valves and measuring station.

Wasting resources: softeners require large amounts of salt and huge amounts of additional water of up to 30-80 gallons per wash (~110-300 l) to operate. They also require lots of manpower as they constantly need to be fine-tuned and controlled. Necessary season-related changes of the water quality (summer/ winter ) are often simply forgotten: the human error factor then prevents the unit from performing correctly.

Health issues: Babies, children, elderly people, people with salt-restricted diets or anyone who is health-conscious should consult a physician regarding the sodium intake increase when using a water softener. The water loses its natural taste and may even taste salty. Also you may have to supplement the important minerals calcium and magnesium in your daily diet.

Note that many water softeners have a by-pass feature that will allow you to bypass the cold water in the kitchen. This will enable you to use unsoftened water for drinking and cooking. In addition, bypassing the cold water tap in the kitchen will prevent minerals from being removed from the water. However, then only part of your pipes are protected.

Water softerners make your water softer. But …is that always a good idea?… is it necessary to have extremely soft water?

The answers are simple: No. and No. Hard water is a real nightmare as long as the scale builds deposits. But the minerals calcium and magnesium are themselves beneficial. Once you minimize the adhesiveness of the scale, it no longer bothers you as deposits but you can benefit from the healthy minerals. Very soft water is also not recommended for pipes as is might damage them (the soft water is too acidic).

Easy installation without cutting the pipes

The Vulcan anti-scale system is designed for an easy installation. You don’t need to cut the pipes which saves time and money. For the installation no special tools are required.

Installation Notes

  • For optimal water treatment Vulcan is best installed near the water meter or at the main water supply.
  • The impulse band windings can be placed on the left side, on the right side or underneath the electronic device. Leave a safe distance of at least 1 cm (min. ~1/2”) from each other.
  • Vulcan can be installed vertically, horizontally or at any other angle. If there is no space available on the pipe the device can also be wall-mounted.
  • In case of limited space the windings can be placed partly on the main pipe and partly on the distributor pipe.

All these different installations are possible because the treatment impulses extend over several meters to either side of the pipes.
