ABSTRACT:
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.
