Colloid-A-Tron selection and installation
The COLLOID-A-TRON is installed in the water lines feeding the equipment that has to be protected. It is sized according to the amount of water flowing through that line. For a given size of CAT there is a minimum flow rate above which it will work effectively. You should select the unit whose minimum flow is nearest to the flow rate through the pipe where you want to install the unit.
Example - Selecting appropriate Colloid-A-Tron Sizes
You have a piece of equipment which is prone to scale up, and you want to protect it. The size of the pipe feeding cooling water to the machine is 2 inches diameter and, generally by looking at the pump characteristics, you estimate the water flow to be about 10 m3/hr. With reference to the table below you will see that your flow of 10m3 lies between 7.5 and 12.6 in the m3/hr column. You should therefore select the 40 mm unit (1½ inches) which is suitable for a minimum flow of 7.5 m3/hr. A flow of 10m3 m3/hr is too little for a 2 inch unit, whose required minimum flow is 12.6 m3/hr. The selected COLLOID-A-TRON is installed in the cold water line between the pump and the machine.
