Using ordinary salt, the Intellichlor salt cell generates free chlorine for your pool. As the salt in the water passes through the Intellichlor cell, it converts to free chlorine and continuously kills bacteria and algae while maintaining the desired sanitation you need to keep your water pure and clean. When the chlorine is finished purifying the pool water, it converts back into salt and the whole cycle repeats. Easy, economical and automatic – simply set the chlorine levels and Intellichlor takes care of the details. Another great upgrade to the Pentair Intellitouch is the IntellipH option which automatically monitors your pools pH and doses the proper amount of muriatic acid to the pool to make sure your pH is always in balance. A pool which implements the Intellitouch control system along with the Intellichlor salt system and IntellipH controller is a truly automated set-it and forget-it pool!
