The machine's highly efficient compressor makes the cold water crisp and ice cold at approximately 47° f without the need of adding ice cubes to your drink.

Makes the water spouts visible in the dark. This water cooler is bottom loading with a cabinet to hold 3 or 5-gallon bottles. The water is pumped from the bottle through the machine. We have incorporated a self-clean ozone function which will automatically clean the machine’s water tank with the injection of ozone by the press of a switch. There is also an empty-bottle indicator that will light up when the bottle needs to be replaced.
