■ Your specification base establishes the type, configuration, base
material, and physical limitations of the cooling tower to be
quoted. During the planning and layout stages of your project,
you will have focused your attention on a cooling tower selection
that fits your space allotment, and whose power usage is accept-
able. Limitations on physical size and total operating horsepower
avoid the introduction of unforeseen operational and site-related
influences. Specifying the number of cells, and the maximum fan
hp/cell will work to your advantage.
Crossflow towers are noted for the accessibility and maintainabil-
ity of all operating components. The spacious interior provides
easy access to fill, drift eliminators, all basin accessories—and is
one of two primary accessways to the fan, Geareducer, and other
mechanical components.
At the fan deck level, the hot water distribution basins are easily
inspected and cleaned—while the tower is operating, if you wish.
The mechanical equipment can also be readily accessed from this
level.
Except for the cold water basin, no counterflow tower component
requiring routine maintenance is as easily accessed. The confined
areas that typify counterflow designs can make difficult work for
maintenance personnel!
