Mashhad Packaging Industries, an Iranian manufacturer of metal cans, has installed two Hydroflow HS-38 units from Hydropath to prevent the build-up of limescale on a welding machine’s valves.

The most important stage of production at the Mashhad base is the welding of the can sides to the base, as it determines the stability and appearance of the final product.

Limescale build-up around the solenoid control valves on the welding machine meant inaccurate and inefficient welding caused damage to the metal.

To combat the problem, a decision was made to trial a limescale-prevention system; Hydropath’s water conditioners were installed, which made a positive impact and so two Hydroflow HS-38 units were fitted permanently.

‘The fact that the Hydroflow range will fit pipe sizes up to 5in (127mm) nominal bore size means the majority of installations can be protected, and for uncommon sizes, custom units can be ordered,’ said Dr Daniel Stefanini, technical director of Hydropath.

Hydropath technology emits randomly varying electric fields producing nuclei throughout the water system.

When the water is heated, the resulting precipitate that is usually deposited on hot surfaces grows in suspension and develops as a crystal on the nuclei, which is then washed away in the flow.

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

More than one year later there have been no problems caused by limescale and therefore no associated maintenance work has been necessary.
