The Intellichlor Power Supply system is designed by Pentair. Working to produce safe, effective, and clean pool water by converting common table salt, into chlorine. Unlike traditional cell systems that run out in the most inopportune times, the Intellichlor features a cell life tracking system. This system communicates the remaining cell hours in real-time so you are never left with dirty water. The easy to use push-button operation makes using this system a delight. While the automatic shut-off features helps to protect, and prolong the life of your cell by enabling it from running for too long. An added benefit is the on-time cycling feature that works to prevent calcium and scale build up, which in turn prolongs the life of the cell.
