Vulcan 3000 Descaler


The electronic alternative to water softeners

The salt-free alternative to softeners
Vulcan is an eco-friendly hard water treatment system that protects your piping system and appliances against scale deposits and rust.

The patented Vulcan Impulse Technology is based on the principle of physical water treatment. Special electronic impulses change the crystallization process of the liquid calcium. This way, hard scale loses its adhesive power.

The technology works exclusively with capacitive electric impulses: no use of any salt, chemicals or magnetism.

  • The eco-friendly alternative to softeners against scale problems — protects your whole house
  • In contrast to water softeners, the Vulcan uses NO salt or chemicalsSee the comparison here.
  • Suitable for pipe diameters from 1/2” to 1.5″** (~ 12-38mm)
  • Fully cast in acrylic for optimal quality endurance
  • Easy, do-it-yourself installation without cutting the pipes
  • Works on every pipe material – iron, copper, stainless steel, galvanized iron, plastic, PVC, PE-X, compound pipes (any material mixture) etc.

How the Vulcan 3000 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 enhances 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 elements 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 older 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 decrease 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).

Vulcan is a proven technology. Take a look at some of the corporate and residential references here.

German 24 Volt Impulse-Technology (capacitive): The water is treated with electric impulses that control scale in an eco-friendly “green” way. It is an electric system that is not magnetic-based. 24v-impulse
Vulcan works on a frequency range between 3-32 kHz with different frequency peaks (wobbling distribution). The secret to the right performance of physical water treatment lies in the composition of these impulses. CWT has developed and fine-tuned them for over 30 years. 3-32khz
Vulcan uses customized isolated copper impulse bands. How the impulses are transferred into the water is crucial. The design of the bands increases the surface area that transports the impulses. This improves transmission by up to 40%. impulse-bands
The original acrylic cast is unique to the Vulcan product line. It offers maximum protection against water, heat, dirt, coldness, humidity and keeps all parts secure and sealed in place. acrylic-cast
Vulcan comes with external UL and TÜV-approved electronic switching adaptors. They operate with a very low power consumption of 100-240V and equalize possible power instability. adapter
Vulcan is not magnetic-based. Therefore, it operates 100% independent of the velocity (water flow rate) in the pipe and constantly provides reliable impulses that guarantee the right output at all times. pipe-water
Material-matching programs for different materials: Vulcan treats any pipe material. No need to buy a different product for metal, PVC, plastic etc. any more. materials
The automatic memory program keeps Vulcan running correctly. In case of the unlikely event of a power failure Vulcan automatically resets back to the last program once power is regained. automatic
Vulcan holds numerous certifications by renowned international institutions: the German TÜV, the German CE, the UL-approval for switching adaptors etc. tuv-ce
Vulcan requires very little electrical power as it is very economical. The units operate with 1.75 to max. 3.25 Watt. The running costs are approx. $US 3-7 (~3-6 EUR) per year. economical
Made-in-Germany: Vulcan is a German quality product that has been manufactured by the family-run Christiani Wassertechnik GmbH, Berlin since 1989. made-in-germany
10-year international warranty is granted for all Vulcan units. Due to the special acrylic protection these units keep on running with a life expectancy of over 30 years. 10-year-warranty
