The Mashhad Packaging
Industries Company in Iran
manufactures metal cans in a
range of shapes and sizes. Its
factory is in a hard water area
and build up of limescale was
a major production problem.

A key stage of production
is the welding of can sides to
the base, as it determines the
stability and appearance of
the final product. Limescale
build-up around solenoid
control valves on the welding
machine meant inaccurate,
inefficient welding.

A decision was
made to trial a
limescale
prevention system.

Hydropath’s water
conditioners were
installed and made
a positive impact, resulting in
two Hydroflow HS-38 units
being fitted permanently. The
Hydroflow range will fit pipe
sizes up to 5in nominal bore
size and, for uncommon
sizes, custom units can be
ordered.

Existing scale is
dissolved in just a
few months and
any future build up
is prevented.

A year after
installation at the
Mashhad factory, there have
been no problems reported
in connection with limescale
and no associated
maintenance work.
