The system how does it work…?

Colloid-A-Tron (CAT) units are installed in 40 countries on 5 continents. Many leading companies have used CAT treatment in countries across the world such as Ford, Bush Beans, Guinness, ICI, Nestle, Carlsberg, Renault and Coca-Cola. Since 1973 hundreds of thousands of customers have benefitted from the installation of the Colloid-A-Tron.

Colloid-A-Tron Technology

Colloid-A-Tron consists of a pipe with a special alloy core inserted inside. The unit comes in different sizes, threaded or flanged as required. In order to prevent scale from forming in a system or a specific piece of equipment a Colloid-A-Tron is installed replacing a section of feed pipe.

The Colloid-A-Tron operates as a catalyst using the pH rise generated by the alloy to trigger precipitation of calcium carbonate in the bulk of the water forming stable crystals. The result is a water that has less calcium and carbon available in solution. That solution has the characteristics of a softer water and therefore does not deposit scale as it passes through the system.

The problem

The formation of scale caused by hard water in pipework and equipment is costly and seriously reduces operating effectiveness. Scaling and its removal manually or by chemicals can cause damage to equipment. Generally the application of chemicals has been the traditional method of handling these problems – however increasing environmental pressures and restrictions are causing responsible industries and plant operators to look for alternative methods. The Fluid Dynamics method of preventing hard water scale is tested and approved by many leading universities and institutions around the world.


The answer

Colloid-A-Tron provides the ideal solution to the problems associated with hard water scaling;

  • Totally safe for the environment
  • Constant supply of treated water
  • Requires no shutdowns for maintenance
  • Uses no energy or electricity
  • Product life expectancy 15 – 25 years
  • Ten year part replacement warranty*
  • Fluid Dynamics is the world leader in non-chemical water treatment systems.

*Warranty is pro rata refurbishment/replacement for materials failure or defect
