The OASIS Ultra S Carbonated Bottle Cooler dispenses refreshing cold still water, piping hot still water, and lively chilled sparkling water. Ultra S provides virtually continuous delivery of water. A two-piece hot water tank also provides eight liters of hot water per hour. Lighted, color-coded LED activation buttons allow for simplicity of use.
A pressure vessel direct chill (PVDC) system combines with a specially designed CO2/water mixer for state-of-the-art chilling and carbonation performance. The pre-carbonated cooled water is taken from the cold tank, pressurized through a pump, and mixed with CO2 gas within a carbonator tank inside the PVDC cooling tank system. The tank is made from food-grade plastics and 304 stainless steel for ultimate safety. The Ultra S carbonates water at 3.2 to 3.5 volumes, similar to leading bottled brands, and can accommodate up to a 5-pound CO2 cylinder (pressure regulator and CO2 cylinder sold separately).
