Abstract: The present invention relates to a fluid cooling system (1), for use in dispensing or distributing a chilled or cooled fluid, comprising a primary heat exchanger system (2), a secondary heat exchanger system (3), a first conduit (9) through which fluid to be cooled or chilled is circulated, and a heat transfer agent (8) for transferring cooling energy to the fluid to be chilled circulating in the first conduit (9), wherein the primary and secondary heat exchanger systems (2, 3) are arranged at least partially one inside of another The invention also relates to cooled fluid dispensers incorporating the fluid cooling system and a methods for sterilization thereof.

Abstract: A gravity-feed unit that dispenses cool drinks form a carboy includes a breakable inner seal. The carboy is supported by its neck, which is centered on a striker. The striker includes a discharge passage for the carboy that communicates with a coiled pipe to cause the beverage to flow through a secondary exchanger. A heat transferring agent is previously cooled in a primary exchanger and brought to the secondary exchanger by a pump. Actuation is controlled by a temperature sensor that measures the temperature of the heat transfer agent in the secondary exchanger. The primary exchanger includes a heat source that causes the heat transfer agent to pass continuously inside a closed circuit mutually connecting the primary and secondary exchangers regardless of whether the pump is operating.
