The Mineral and Scale Eliminations System is the best product on the market for preventing scale and mineral buildup in your evaporative cooler. It does this by automatically flushing out the cooler's old water at regularly timed intervals. Without it， scale will continually build up in the cooler pads， restricting the flow of cool air. This system ensures against this by regularly flushing the old water out through the cooler drain and replenishing the cooler with fresh water. This 115-Volt system does not replace the regular pump but works alongside it.
