The Dow KATHON™ 7TL Dosage Calculator is a simple application where users can input values into any two of three input fields – the volume of their water cooling tower (in either m³ or gallons), the concentration (in ppm) and Dose (in number of tablets) – to obtain the third value. The Calculator will enable users to quickly determine how many KATHON tablets are necessary to safely and accurately treat the water in the cooling tower. Users who have questions about the product can easily submit form via the application that is sent to a Dow expert.
