Praxair Inc. has recently announced that its subsidiary NuCO2, the largest fountain beverage carbonation provider in the U.S., has launched the XactCO2 HP (high-pressure) patent-pending fill system. It’s a permanent, scalable carbon dioxide cylinder supply system for restaurants and bars. The XactCO2 HP fill system is currently being launched in Denver, Atlanta, and the greater San Francisco area. It will be launched in the country later this year. Discussing the working of the new system, it contains cylinders connected to a small fill box located outside the site. Interestingly, the fill box is just 6 inches by 6 inches in dimensions with 2 inches of depth.
