Limescale problems scaled down for can maker

The Mashhad Packaging Industries Company in Iran makes metal cans for factories and food industries.

Its factory is in a hard water area and limescale build up around solenoid control valves on a welding machine used to weld can sides to their base meant inaccurate and inefficient welding leading to damage to the metal.

Following a successful trial, two of Hydropath's HS- 38 water conditioners were fitted permanently.

The Hydroflow range will fit pipe sizes to 5in nominal bore size; custom units can be ordered.

Hydropath technology emits randomly varying electric fields producing nuclei throughout the water system.When water is heated, 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. Scale is dissolved in just a few months.

It is over a year since the units were installed and no limescale problems have been reported.
