Salt Water Concrete Cooling Towers - Design Considerations

A properly designed cooling tower promotes the maximum possible contact between air and water—and does so for the maximum possible time period. This effort on the part of the designer results in an efficiency which, although greatly appreciated in the summertime, has the capability to produce performance-degrading ice formations during winter operation.

A cooling tower reacts much like a human being to its air supply. If it is caused to reinhale its own exhaust, it begins to smother. If that air supply is restricted, it begins to choke.

Les coûts énergétiques et l’efficacité opérationnelle ont pris une importance considérable dans l’esprit de nombreux propriétaires de bâtiments et exploitants d’installations ces dernières années. Les perspectives actuelles concernant les prix futurs des ressources énergétiques suggèrent que ces questions deviendront encore plus urgentes à mesure que les préoccupations environnementales et le coût élevé de l’argent exercent un impact toujours plus grand sur la conception et l’exploitation des bâtiments.

Factory assembled cooling towers have been manufactured from "heavy mill galvanized" (HMG) steel for many years. HMG steel is continuously hot dip coated with protective zinc at the steel processing mill. The steel is treated subsequent to coating with a chromate rinse to initially passivate the zinc surface, providing for protection during storage, fabrication and initial operation from "wet storage stain".
