The ION Water Cooler has a proprietary design and sealed waterway where your water is freshly filtered and instantly chilled. Think of this as a “tankless” water cooler. The water lines are run through a bank of ice that instantly chills the water without the need for an internal reservoir. This means that the ION Cooler produces more cold water than any other water cooler, all while using less energy. The 9” spigot clearance allows you to easily fill glasses, bottles and most pitchers with ease.
