Pool Controls Gemini 30CX Controlled Salt Sanitation Systems

The Gemini CX is a fully integrated ORP-controlled salt (or mineral) chlorinator with pH control.

The Gemini Control unit analyses water quality via a multi-electrode probe and activates the Sterisel salt or mineral chlorinator as needed.  

The pH of the water is also monitored and adjusted with precise does of acid via a peristaltic pump.
 Controlled salt systems potentially provide pool owners with the best of both worlds – the precision of an ORP-controlled 
system and the convenience of salt chlorination.  However, these sophisticated systems require other aspects of water 
chemistry to be well-maintained if they are to operate effectively.
 If you are considering this type of system for your pool, ensure you have a good grasp of swimming pool water chemistry 
so that you get the most out of your investment!
