Disclosed is a water dispensing machine and a carbonated beverage dispensing system which facilitates a combination of carbon dioxide with water in a configuration which provides a smaller footprint and reduces or eliminates dependency on remotely located carbon dioxide tanks and flavoring systems.
Disclosed is a water dispensing machine and a carbonated beverage dispensing system which facilitates a combination of carbon dioxide with water in a configuration which provides a smaller footprint and reduces or eliminates dependency on remotely located carbon dioxide tanks and flavoring systems. The system may be configured to produce only carbonated water or to allow the user to select carbonated water or chilled water, and, alternatively, ambient, unchilled water. A carbonator of the system introduces carbon dioxide to a chilled water stream using an injector with slots. This inline, on demand carbonation system provides benefits over carbonator tank systems which carbonate large volumes of carbonated water in bulk.
