A closed, low volume, pressurized cooling system for cooling beverages transported through conveying lines from a beverage source to a dispensing station. The pressurized, low gallonage coolant system has its coolant (water/glycol) cooled by a refrigeration system. The coolant is recirculated on a continuous basis and has a cooling line in contact with the beverage conveying lines to chill the beverages contained in the beverage conveying lines. A thermostat monitors the temperature of the coolant and the refrigeration unit runs only on demand. The coolant in the cooling system is pressurized by a bladder type pressure tank. The closed, pressurized coolant system minimizes separation and evaporization of the coolant and prevents contamination of the coolant.
