Elkay Commercial Products offers its EZ Green water cooler models combined with the EZH2O bottle-filling station. Elkay’s efficient models provide 35% more energy savings than the industry average. A Green Ticker on the front of the unit displays the running total of 20-oz. disposable water bottles saved. The station provides a rapid fill of 1 gpm for refrigerated models and 1.5 gpm for nonrefrigerated models. EZH2O can fill a 16-oz. sports bottle in as little as 6.5 seconds. Elkay.
