A chiller tank system for containment of chilled liquids comprises a first tank and a second tank position within the first tank. The first tank is spaced apart from the second tank so that insulation material can be positioned between them The second tank defines a chamber for receiving the liquid to be chilled. A straight-lined, chiller barrel is positioned vertically within the chamber, the chiller barrel defining a bore connected to a flexible, dual hose. The straight-lined chiller barrel extends downward into the tank thereby evenly chilling the liquid to avoid thermal stratification that causes vaporization by creating warm spots within the liquid. A refrigeration unit supplies inert refrigerant to the tank. The dual hose circulates refrigerant between the refrigeration unit and the chiller barrel, the dual hose comprising an inner hose within an outer hose, the outer hose concentric to and spaced apart from the inner hose thereby creating two channels, one for transporting the refrigerant to the chiller barrel and the other for transporting the refrigerant away from the chiller barrel.
