Abstract
The present disclosure relates to a self-contained high pressure pneumatic beverage dispensing system. In one embodiment, the system comprises a carbonator tank for facilitating absorption of CO.sub.2 gas in water to produce carbonated water, a refillable source of CO.sub.2 gas under high pressure, the source of CO.sub.2 gas in fluid communication with the carbonator tank so as to fill the carbonator tank with CO.sub.2 gas, a source of water under high pressure and in fluid communication with the carbonator tank so as to fill the carbonator tank with water, at least one pneumatic pump in fluid communication with the source of CO.sub.2 gas, at least one liquid reservoir, for example a bag-in-box container, in fluid communication with the at least one pneumatic pump, and a beverage dispenser valve in fluid communication with the carbonator tank and the at least one liquid reservoir, wherein the beverage dispenser valve can dispense carbonated water and/or the liquid held in the at least one liquid reservoir when activated by the operator.
