14. Frequently Asked Questions
How do I know that the Vulcan is operating efficiently?
Red pilot lights at the impulse band outputs indicate that the impulse
generator is operating efficiently. In case these lights are not illuminated,
please check the power supply voltage or contact your local distributor.
Which voltage ranges are suitable for the electronic power
supply unit?
All Vulcan power supply units are suitable for voltage
ranges between 87 Volt – 260 Volt and 50 Hz – 60 Hz. It can therefore
easily caters to all international power plugs. We are glad to supply you
with the correct power supply unit in case of an international relocation.
How many units do I need?
Private homes are taken care of with one
unit that treats the whole house. In larger buildings or industrial settings
it depends. Typically, one larger unit gets installed on the incoming water
supply line to the building. If you have a cooling tower or closed loop
systems, another smaller unit would go there.
What are the power costs of Vulcan per year?
Vulcan is completely maintenance-free. The cost of electric energy per year
amounts to approx. 4-5 € (~$ US 5-7).
14.4 Miscellaneous
What kind of warranty do I get on Vulcan?
Vulcan has a full 10-year warranty and has a 30+ year life span. It is
German TÜV-certified and is CE, CUL and UL listed. Your Vulcan unit is
100% covered under most circumstances. The units have an expected
life of over 30 years and are imbedded in weather proof acrylic casts. By
purchasing from the manufacturer and listed distributors, your warranty
is well-assured. German quality standards and excellent customer
service have been our priority for over 60 years.
I heard of similar products which don‘t work. Can you explain?
There are similar products to Vulcan on the market that claim to do the
job, but don‘t. Almost all other products on the market are working with
inductive (electromagnetic) technologies. You can easily recognize them by
their cables. Those cables run in a loop from the electronic unit - to the pipe
and back into the unit (pic. 1).
In comparison, Vulcan works exclusively with capacitive impulses that
guarantee a stable output. Its impulse bands end on the pipes, similar to
antennas. Furthermore, regardless of inductive or capacitive impulses: Vulcan
utilizes far wider frequencies of 3,000 - 32,000 Hz (= 3-32 kHz) and operates
with energy levels at 24V. Read more on the differences in technologies on
page 16. Christiani Wassertechnik (CWT) is the oldest German manufacturer
of physical water treatment. The product specialization in this field began in
1977 and we are constantly developing new technologies.
