FortiCool D-scaler tackles mineral scale buildup while helping you maintain efficient, low-maintenance cool cells. Hard water and dirty evaporative coolers often lead to stubborn scale deposits that reduce system performance. FortiCool D-scaler combats this by gradually releasing scale-fighting ingredients through its advanced polymer technology. This slow-release action not only prevents new buildup but also extends pad life and improves cooling efficiency. To keep your system running at its best, replace FortiCool D-scaler every 30 days.
