Title: Method and system for creating and maintaining a frozen surface

Abstract: A method of constructing a heat exchange system for a medium to be frozen, including the steps of: extruding a composition to form a reconfigurable tube; cooling the tube with the tube in a substantially straight configuration so that the tube is substantially set in the straight configuration; after cooling, reconfiguring the tube from the straight configuration; transporting the tube reconfigured from the straight configuration to a site at which the tube is to be used; and at the site placing the tube in the straight configuration and connecting the tube in a medium to be frozen so that a fluid within the tube is in heat exchange relationship with the medium to be frozen.
