In one aspect, a carbonator tank has a cooling coil (71, Fig.7) extending around the tank. In another aspect, a tubular heat exchanger surrounds an outer surface of the tank for heat transfer between the liquid in the carbonator and the fluid in the heat exchanger. In a third aspect, the carbonator has a pre-coil wrapped around the tank and at least one of the pre-coil and the cooling coil are in contact with the outer surface of the tank and with the other coil. The tank may have a bowl 37a and a lid 37b. The lid 37b is provided with an inlet 39 for still water, an inlet 41 for carbonating gas and an outlet 43 for carbonated water. The water inlet 41 is connected to a supply line 48 that includes the pre-cool coil 49 that is wrapped around and contacts an outer surface of the cooling coil 71. Coolant in cooling coil 71 cools the still water delivered to the tank in the pre-cool coil 49 and the carbonated water in the tank. |
