  • the apparatus for treatment and distribution of beverages being the object of the present invention enables quality preservation of the water to be dispensed.
  • the ungassed water is no longer subjected to long residence periods, as it happened in the known art, in huge storage tanks, with consequent risks of bacterial proliferation.
  • the water reaches the dispenser 2 or saturator 6 directly from the water distribution system, after instantaneous cooling through the heat exchanger 16 plunged in the gassed water.
  • the sizes of apparatus 1 have been greatly reduced and at the same time the container 10 for collection of the gassed water of saturator 6 has been greatly enlarged, thereby enabling the high demand for gassed water to be met.
  • the increase in size of container 10 has consequently also brought to an increase in the contact surface between the gassed water mass contained therein and the overlying carbon dioxide, thereby further promoting dissolution of carbon dioxide.
  • This feature also enables the gassing device to be operated to a reduced operating pressure as compared with the known art.
  • Use of a less powerful hydraulic pump 14 than required in the known art is therefore possible, and the pump itself may be even eliminated by utilizing the water-supply pressure from the water distribution system alone.
  • the overall dimensions of apparatus 1 can be further reduced, which will bring about reductions in the manufacturing and operating costs.
  • the particular structure of the coil 17 of the heat exchanger 16 greatly promotes heat exchange between the cooled gassed water and the ungassed water at room temperature.
  • arrangement of polygonal turns 17a angularly offset with respect to each other, as above specified enables the coil length to be increased, bulkiness being the same, and consequently the heat exchange surface to be increased as well, while the contact regions due to overlapping of contiguous turns are reduced to a minimum.
  • Another advantage resulting from this configuration is due to the fact that, in spite of the presence of coil 17, the water being gassed is free to circulate within container 10.
  • offsetting between one turn 17a and another defines a series of passage loops that can be passed through by the water following a labyrinth path.
