Product information
2.2.1 JUL mineral solution
The following JUL mineral solutions are
available:
•
JUL-W (Tabs; not for Switzerland)
•
JUL-H (Tabs)
JUL-W
Application:
Galvanized pipes
Method of operation:
Orthophosphates and silicates react with
the metal of the piping to form a difficult-to-
dissolve compound, so that the pipe mater-
ial is shielded against the corrosive effects
of the water.
JUL-H
Application:
Mixed-metal installations
Method of operation:
The polyphosphates surround the calcium
and magnesium ions responsible for the
hardness, preventing them from forming
any more calcium/magnesium carbonate
(limescale) crystals.
Notes:
•
The hardness stabilisation process was
checked according to the DVGW (Ger-
man Technical and Scientific Associ-
ation for Gas and Water) worksheet
W 512 at 80 °C; the result was a certi-
fied reduction of limescale formation of
more than 99 %.
•
The hardness stabilisation occurs even
when only small phosphate quantities
are used, so that when using JUL-H,
the specified strict limit values for phos-
phates in drinking water are adhered to.
2.3
Remote monitoring
The device can be integrated in building
control systems (see chapter 6).
2.4
Materials used
The materials used are resistant to the
physical, chemical and corrosive loads
expected to be encountered in drinking
water. They fulfil the specifications required
by DIN EN 19635 (“Dosing apparatus for
drinking water treatment”).
All materials are hygienically and phys-
iologically harmless. Plastics fulfil the
KTW Guideline (Guideline for the Hygienic
Assessment of Organic Materials in Contact
with Drinking water) of the DVGW Work-
sheet W 270. Metallic materials fulfil the
requirements of DIN 50930-6 (Effect of
metallic materials on the quality of drinking
water).
2.5
Approval marks
The device complies with the technical
regulations for drinking water installa-
tion according to DIN EN 806ff. and the
national supplement DIN 1988ff. as well as
DIN EN 1717.
It has been tested and certified by the
DVGW (Deutsche Vereinigung des Gas-
und Wasserfaches e. V. - Technisch-wis-
senschaftlicher Verein) in accordance with
the requirements
• of DIN EN 14812
• of DIN EN 19635-100
(pressure range PN10). The device bears
the DIN-DVGW mark as proof of certifica-
tion.
