<p>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 control the refrigeration system in response to a need for or in response to a sufficiency of ice 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 through a tube extending along a freezing surface on the evaporator, the tube leading to a reservoir in which there is a sensing control responsive to the water level, the reservoir returning water to the bath.</p> |
