The Baudelot type cooler consists of a series of horizontal tubes that are located one underneath the other, and are connected to form a refrigerant circuit or circuits. For flooded or dry expansion operation, the refrigerant is circulated through the interior of the tubes, while the cooled liquid flows outwardly into a film fin. The liquid flows down the tube by gravity from a dispenser located on top of the refrigerator and is collected inside a chute at the base. The fact that the cooled liquid is at atmospheric pressure and in contact with the air, makes the Baudelot type refrigerator ideal for any application of liquid cooling where aeration is a factor. The Baudelot type cooler was widely used for cooling milk, wine and unfermented beer and for cooling water for carbonation in the filling lines. With this particular type of cooling, it is possible to cool the liquid to a temperature very close to the freezing point without the danger of damaging the equipment if occasional freezing occurs.
Another advantage of the Baudelot type cooler, which is also offered by the dual tube cooler is that the refrigerant circuit is readily divided into several parts, a circumstance that allows pre-cooling of the cooled liquid
with cold water before the liquid enters the direct expanding part of the refrigerator.
