Product Information

vulcan models

The Vulcan Descaler is an innovative device that has been improved upon for over 30 years and comes with an extensive and well documented success track record.

The 5000 model is engineered to work with a pipe diameter of up to 2 inches and will work exceptionally well for residential homes, including commercial environments such as restaurants, bed and breakfasts, beauty salons, and many other types of business even though it is ranked as a residential solution.

If you live in a very large home; over 9,000 square feet consider upgrading to the S10 model (entry level commercial line). Although it costs around 45% more than the Vulcan 5000 model; the S10 is engineered to work with 65 GPM water flow; almost doubling the capacity of the top residential model. This capability will far exceed your requirements of 4+ bathrooms, swimming pool, hot tubs, jet tubs, irrigation system, etc. It will give you the absolute assurance knowing the descaler you installed will continuously make sure that anything your water touches will be clean and extend the lifespan of your appliances and equipment.
Alternatively, additional Vulcan 5000 or 3000 models can be installed in strategic locations (dedicated to pool and spa environments).

If your company has larger water main lines, and you know your water flows at about 35 GPM; our suggestion would be to upgrade to the commercial line of the Vulcan descaler and invest in the S10 model. Even if your company moves to a new location you can always unplug the device and take it with you.

Installation is quick, easy and you do NOT have to hire a plumber:

Installation Notes: 

vulcan installation notes
For optimal water treatment it is best to install the Vulcan Descaler near the water meter or at the main water supply.

It 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.

The impulse bands can be wound awound a pipe on the left side, on the right side or underneath the electronic device. In the event of limited space; the windings can be placed partly on the main pipe and partly on the distributor pipe; the treatment impulses extend over several meters to either side of the pipes. Temperature peaks on heating element surfaces should not exceed ~203°F .

Leave a safe distance of at least ½ inch between the bands. Do not remove the end caps or the impulse band insulation. Do not cut the impulse bands or the 24 V power cord of the power supply unit.

Use the provided electronic switching adaptor only. Protect the electronic unit and the power supply against direct water. Only specific Vulcan units (produced on demand) can run under water. ONLY use water to clean the Vulcan device.

The operating temperature of Vulcan ranges from -13°F to 122°F.

Installation Steps: 

1. Put the two cable clips through the holes at the bottom of the electronic device and then place it on the pipe. Using the cable clips, latch the device onto the pipe.

2. Connect one of the impulse bands to the device and use another cable clip to latch it to the pipe.

3. Wind the impulse bands around the pipe producing a coil. Make sure you wind the band tightly to the pipe and place the impluse bands close to each other.

4. Latch the end of the impulse band to the pipe using another cable clip. Now repeat the procedure with the second impulse band.

5. First, plug the connector into the upper right in-jack of the device and then plug the power supply unit into an electrical outlet.

6. The red pilot lights will illuminate as soon as it starts to operate. Your hard water descaler is NOW operational and will continue to work; maintenance-free.

Has the installation location been chosen with respect to these factors?
Time Factor (water in tanks max. 48 h)
Heat Factor (Temperature peaks on heating element surfaces should not exceed ~203°F)
Distance Factor (max. 2 km / 1.24 mile pipeline length)

Are there unusual high levels of certain substances in the water? If yes, have they ben taken care of?
Example: Iron (Fe) and other metals: The content of iron and other metals in the water should not exceed 1 mg/l (1 ppm).
Other metals, for example: copper(Cu), aluminum(Al), lead(Pb), nickel(Ni), Zinc(Zn) can affect the Vulcan treatment.
Mn: The manganese level should not exceed 0.1 mg/l (0.1 ppm)

Have filter and pumps locations of been taken into consideration?
As a general rule it is better to install Vulcan after a pump and after a filter, if the setting in your installation area allows it.
Filters: Crude filters (> 50 μ) do not remove the mono-crystals and can be ignored. For more sensitive filters (< 50 μ).  it is recommended to install Vulcan after the filter.

Pumps: If possible, we advise installing Vulcan after any pumps.
WHY? : Pumps with internal plastic wheels may create an electrical field that may affect the electronic impulse results of the descaler. Pumps with internal metal wheels may also cause an effect on the altered hard water molecules. If you know your pump does NOT create a very strong electrical field then install the Vulcan device before the pump on your main water line. If you are uncertain install after your main water pump.
Filters: If possible, we advise installing Vulcan after any pumps.
WHY?: Water filters are manufactured in a very wide variety of membranes and mediums; very small membrane water pathways can potentially filter out the treated hard water crystals. In general, install the Vulcan after your main water filter system.

Have you checked for strong electricity, magnetic fields or electro-motors?
Please make sure that there are no strong electric lines running close to the installation area. High voltage electric lines or strong magnetic fields may interfere with the Vulcan impulse-field. Please install Vulcan approximately 1 ½ to 3 feet away from these fields.

Are paint or cover materials on the pipe taken care of?
Thin coatings such as pipe protection (e.g. corrosion protection paint) are suitable to place the impulse-bands directly on top.
Insulation material or other thicker protective layers should be dismantled and can be re-installed over the impulse bands after installation.

Is the pipe surface temperature suitable?
The pipe’s outside temperature should not exceed ~ 149° F. Above this may harm the isolation of the copper impulse bands.
