Maintain a Healthy, Sparkling Pool

The RolaChem 9 series provides ongoing sanitiser management of your pool or spa so that it always looks great, safe, and healthy to swim in. With sophisticated sensors and software programming, the sanitiser level is continuously monitored and adjusted according to your swimming pool or spas requirements, weather conditions or bather load. All while dramatically reducing the maintenance required for your pool and spa.

The RO9 provides the function of advanced measure and control of your sanitiser activity which means lower usage of sanitiser, saving you money. By constantly measuring and dosing sanitiser to maintain the correct set point, the RO9 controller ensures the sanitiser in your water is at its optimal level.



The RO9 can automatically control your filter pump operating hours with its inbuilt timeclock and the “Spa” button changes the dosing rate to suit the smaller volume of your spa when isolated from the pool.
