The formation of hard water scale in piping networks of cooling circuits and heat exchangers reduces the internal diameter of pipes by the formation of insulating layers of scale, resulting in costly maintenance, increased energy costs, production down-time, and equipment deterioration.
The application of chemicals for the reduction of scale is not always economical and is, on occasion, prohibited. For example, in the Food Industry the application of chemicals is limited, particularly as the purity of the water may not be altered. In addition, the application of chemicals in water treatment often involves high investment, and operations, maintenance and servicing costs.

HOW COLLOID-A-TRON WORKS?
The secret of operation is found within the core of the Colloid-A-Tron, its shape, its composition and a combination of pressure changes and turbulence. This operates as a catalyst, causing colloidal particles in the bulk of the solution.
In the water to be treated the hardness salts, when flowing through the Colloid-A-Tron, are attracted by the galvanic potential at the surface of the core. There colloidal particles from but cannot settle because of the particle shape of the core allied to the combination of turbulence and flow.
The result is that a suspension of colloidal particles within the water is created, thus preventing the formation of scale on heat exchanger walls. It has been know that systems already scaled prior to installation, have had this scale loosened and dissolved over a period by the Colloid-A-Tron, due to changes in the environment.

THE ANSWER
Colloid-A-Tron provides the ideal solution of hard water treatment problems. It eliminates the use of chemicals; has no moveable parts; requires no maintenance or energy consumption; and is non-sacrificial.
Colloid-A-Tron is the world leader in non-chemical water treatment and has been widely tested. The carbonate salts in the water are physically modified while remaining in the water having flowed over the Colloid-A-Tron.
Thus the water is not softened and, consequently, does not become corrosive. The chemical composition of water remains unchanged after passing over the Colloid-A-Tron.

Case Histories
Food and consumer product industry:
Colloid-A-Tron have been fitted by well-known Breweries for cooling and bottle cleaning machines. Since the installation there have been no further problems. Successful installation have also been carried out in Meat Factories and Companies specializing in refrigerated products.

Metal and plastic industries:
There are many possibilities for the use of Colloid-A-Tron here. The fact that the units operates without any need for maintenance avoids production stop-page, which is particularly important in metal production, plastics and the motor industry.

Hot water treatment:
The installation of Colloid-A-Tron in heat exchanger pipe networks prevents scale formation. They have been successful installed in Commercial and Office Buildings and Apartment Blocks, where variable water qualities are found.

Administrative buildings:
Colloid-A-Tron prevents scale in cooling towers and humidifiers, such as those installed in larger hotels, hospitals or office buildings, thus eliminating the need for costly appliances using chemical products.
