Baudelot coolers and ice Bank coil

1. Baudelot coolers . The evaporator is above the tank, and the water flows down on the outer surface of a thin layer. Evaporator construction can be coils or plates, stamping. The latter, as a rule, of stainless steel to prevent corrosion. Evaporators can be flooded with water or direct expansion. During operation Baudelot cooler can sometimes create a thin layer of ice, but it does not cause damage to the evaporator, and should melt off again when the load changes.
2. Coils in a water tank. As flooded and direct expansion evaporator used. Water is circulated by pumps and/or special agitators. This type of cooler water can be operated without the formation of ice, or ice can be allowed to accumulate intentionally (see below).
