A beverage dispenser includes a gas infusion device that receives a base fluid and a gas and dispenses a gas infused liquid, a ratio pump that receives the gas infused liquid and a concentrate from a concentrate source and dispenses a predetermined ratio of the gas infused liquid and the concentrate, and a mixing chamber that mixes the predetermined ratio of the gas infused liquid and the concentrate to form a reconstituted beverage. An insulated enclosure has an interior space in which the ratio pump and the mixing chamber are positioned. A cooling heat exchanger is positioned in the insulated enclosure, and a first refrigeration system circulates a cooling media through the cooling heat exchanger to thereby cool the interior space to a suitable temperature such that the gas infused liquid and the concentrate dispensed from the ratio pump and the mixing chamber are cooled to the suitable temperature.

A primary beverage cooling circuit for refrigerating a fluid used in a secondary beverage cooling circuit cools beverage in a beverage conduit by pumping the fluid through a heat exchange conduit adjacent the beverage conduit to transfer heat therebetween. The primary beverage cooling circuit includes a refrigerant circuit containing a refrigerant circulating through a heat exchanger in heat transfer communication with the fluid to cool the fluid, a variable displacement compressor for circulating the refrigerant through the refrigerant circuit, a cooling device for cooling the refrigerant, and a valve for controlling the volume of fluid into the heat exchanger. The primary beverage cooling circuit further includes a controller for controlling the operation of the compressor and/or the cooling device and/or the valve based on one or more measurements from temperature and/or pressure sensors in the refrigerant circuit to maintain a temperature of the fluid and/or refrigerant about a set-point temperature.

Systems and devices for cooling and dispensing a beverage fluid are disclosed herein. One beverage dispensing system includes a beverage tower comprising a tower body, a shank, and a faucet. In some implementations, a coolant line is routed proximal to a beverage supply line through the tower body, through the shank, and into the faucet. In these and other implementations, the faucet includes a removable nozzle having a supplemental portion of the coolant line. In these and still other implementations, the faucet include a removable nozzle having a second coolant line. The coolant line and the second coolant line are configured to transport a coolant medium proximal to a beverage fluid in the beverage supply line to maintain or adjust the temperature of the beverage fluid. Many other features are described herein.

The disclosure concerns a dispensing system having a multi-tower modular dispensing system that includes at least a first dispensing head and a second dispensing head at a counter and a transfer unit located remotely from the counter. Piping extends from the transfer unit to the counter. The transfer unit includes a centralized ingredient system having a plurality of beverage ingredient sources. The centralized ingredient system is configured to supply beverage ingredients to the piping for the dispensing of a first beverage at the counter. The piping includes a main micro bundle that includes at least two separate beverage ingredient lines.

A beverage dispensing system includes a cabinet with a dispensing station. The cabinet includes therein a refrigeration system, a cooling fluid system, and a refrigerated compartment having therein a cooling system and a beverage source coupled with the dispensing station. The cooling fluid system circulates a cooling fluid through the refrigeration system such that the refrigeration system cools the cooling fluid. The cooling fluid system further normally circulates the cooling fluid through the dispensing station to cool beverage therein. The cooling fluid system directs the cooling fluid from the dispensing station to the cooling system when necessary to cool the refrigerated compartment. A beverage fluid system resides in the cooling fluid system between the beverage source and the dispensing station such that the cooling fluid system cools beverage flowing through the beverage fluid system prior to delivery of beverage to the dispensing station for dispensing therefrom.
