Our
proportioning device has been realized to avoid expensive
scaling from washing.machine and from pipe-ring of moderm
wall central heating.By using Ventury System the polyphosphate
dosage is in proportion to the water flow, that guarantees
an exact and constant product injection on observance of
drinkable water law.The poliphosphate micro-dosage neutralized
effcaciously the precipitation of calcium-carbonate and
magnesium up to a temperature of 70°-80° C making
a protective coat over metallics shares in contact with
water. Every 1,000 litres of delivery water the approximate
polyphosphate' s dosage is 5 ppm which means 3 ppm of p2o5

After
the P.D. practicality, this model, also, offers a double
function possibility: by-pass of the proportioning device
on general water block. Without disconnecting the water
flow, is possible to operate on the glass reloading with
polyphosphates, with an easy shiffing of the valve(patented
model), in three positions. Otherwise close the delivery
to the proportioning device and turn off the elettrical
appliance to which it is connected.This possibility avoid
further installation of block-valve and allows electrical
appliance repair which it is applied for example to the
mural heater or in the washing machine. The versatily of
these two models allows the installation over planes, verticals
and obliques pipes.

This
is the easing and restrained of three models proposed by
Opur, The water connection input/output is fixed and layed
over the axle-head. Using reliable materials Opur privilege,
as for others models,quality. The brss shares are forged
to avoid accidents of blowhole verifiable, sometimes, in
die-casting. The Trogamid T glass is made in plastic materials
resistant at presure at the ageing and to the noxious action
of sun ultraviolet rays.Every parcel glasses is dily submitted
to a burst and to an ageing duration tests at least 100,000
stresses from 0 to 20 Bar. The pressure-test is of 50/55
Bar

We
recommended the proportioning device DP 5 plan for new waterworks
installation, to avoid the limestone formation or hard water
corrosion.We notice that is enough a calcium carbonate incrustation
of 1,5 mm to reduce the central heating effect of 11%. The
DP 5 proportioning device assures for old plans, a protective
coat production over metallics shares in contact with water
in order to avoid the corrosion caused by a slow water erosion..
Opur suggests two differents polyphosphate types: PS !/h
for hard water (from 15° F on), PS 1/W for soft water
(from 3° F till 15°F). The structural arrangements
of this model are: crome-plated and buffed brass head, ring
and pipe fitting; Trogamid T glass shatter-proof and antiageing;
bellows in naturalrubber for food processing use; polyphosphate
for food processing use according to German law; extractable
calibration nozzles, for cleaner; glass capacity with o-ring
at beaten on head; shutting of head-glass with an original
and pratical stay-ring; separation from hard water to the
treated water with 2 o-ring capacity.
