Technical
test data.
This test was performed with ordinary tap drinking water from
a sub-soil well 50 meters (164 ft.) deep and with water hardness
of 21 odH (375 PPM / 3.75 mmol/l).
Test system
description.
The cold water supply is
connected to the inlet at the top of sealed windings, for inside
flow in these to cool the steam coming from the boiling water
below. The water at the end of the windings reaches a temperature
equal to the
normal hot water supply (55 oC to 65 oC).
A part of this water is supplied to
compensate the evaporated water in the boiling chamber below
with a 2000 kW heating element. The evaporated steam is pressurised
into the glass tube
surrounded by the windings and escape by a number of holes in
the upper outside chamber. The steam is transformed into distillated
water by the cooling
windings and drained from the bottom of the upper compartment.
Hard water will build up lime scale inside the coolant windings,
which should be dissolved after implementing the product to be
tested into the cold water supply pipeline. By failing to do
so, it is ineffective!
The test
system simulates water installation systems in buildings.
The glass windings may
be compared with a heat exchanger and the boiling compartment
below with a washing machine with a heating element. In
physical terms the same procedure takes place in all water supply
systems and cause lime scale deposits. The advantage of the test
apparatus: being of glass the limestone build-up and/or dissolving
can be determined by simple viewing.
Recommendation
Many "magnetic, electrical
and magic" products claim to prevent and remove lime scale
deposits in households, apartment buildings and industry plant.
Many of these products are doubtful and only the customers are
"treated". The test above gives evidence of the function
results to be expected and will
discover any product not meeting its claimed performance. No
scientific
education is required to perform the test or evaluate the results.
For the benefit of the many persons which might be "treated"
by useless
products, it is recommended responsible consumer organisations,
institutes and authorities start a series of product tests as
soon as possible - it is easy and cheap! As a serious producer
we recommend and support
such tests worldwide. |
