Fluid cooling system

The system for cooling fluid stored in a generally cylindrical container includes a generally cylindrical hollow coil element (130) having an engaged orientation for engaging the container and at least one disengaged orientation in which the container is disengaged. The hollow coil element (130) is configured to provide thermal engagement between a refrigerant fluid located interiorly thereof and the container when the hollow coil element (130) is in the engaged orientation. The hollow coil element (130) includes at least one elongate hollow element with a nonuniform generally spiral configuration, wherein the spiral defines a plurality of turns of the elongate hollow element (130). There is also disclosed a system for cooling gaseous fluid stored in a selectably disengageable container. The system includes receiving apparatus for selectably receiving the container, cooling apparatus for providing a refrigerant fluid in thermal engagement with the container and apparatus for substantially preventing forceable egress of the gaseous fluid from the container when the container is opened.
