A beverage dispenser includes a source of pressurized carbonated beverage which is connected to a dispensing valve by a line extending through a refrigerated bath. In the bath, the line includes a thin-wall high-density polyethylene tubing portion having a wall thickness in the range of 0.018 to 0.028, preferably 0.025 inch, and a density in the range of 0.945 to 0.965, preferably between 0.95 and 0.96.

A beverage cooling bath includes a refrigeration evaporator immersed in water for growing ice thereon, there being a beverage cooling coil disposed elsewhere in such water. In order to turn the refrigeration system off when a sufficient amount of ice has built up on the evaporator, there is provided a control for doing so which includes a motor-driven impeller that directs a flow of water into a tube which divides, the one portion having an outlet through which such water normally flows along a freezing surface on the evaporator, and the other portion being a branch that leads to a sensing control which is responsive to an increase of water level or water pressure therein as a consequence of ice forming to block the other portion leading to the outlet.

A nozzle assembly has a body with an axially closed end, and a radially apertured cup-like discharge chamber on the outside of the closed end, and a nozzle cap carried on the outside of the body, and having an annular seat surrounding its discharge opening, the seat being engageable with the body around the discharge chamber. The assembly is adapted to be non-threadedly secured to a source of liquid pressure, there being an extension which can be disposed between such source of liquid pressure and the body. The spray nozzle and spray nozzle extension are adapted to be connected to the discharge of a pump by which the pump is converted into a sprayer.
