Specification Value
Air Inlet Screens:
6.3 Add the following paragraph in the
Fill, Louvers and Drift Eliminators
section: The air inlet faces of the
tower shall be covered by 1" mesh
stainless steel welded wire screens.
Screens shall be secured to stainless
steel frames, and shall be removable.
Appearance Options
Architectural Casing:
8.1 Replace paragraph 8.1 with the
following: Tower endwalls, as well as
exposed hot water basin sides above
the louvered face, shall be cased
with horizontally-installed, pultruded
fiberglass panels. Tower corners shall
be finished with pultruded fiberglass
angles.
Cased Guardrail:
8.1 Add the following to the end of
this paragraph: The casing and cor-
ner treatment shall extend to the full
height of the guardrail described in
paragraph 9.2. The additional wind
loading imposed by this exposure shall
be accounted for in the tower's struc-
tural design.
■ In wooded or windy areas, these screens help to keep leaves or
blowing debris out of the cooling tower and circulating water
system.
■ This is an architecturally pleasing, heavy duty casing that pro-
vides an appearance similar to shiplap siding. See cover photo.
■ Extending the casing to the top of the fan deck guardrail presents
a clean architectural appearance by shielding the mechanical
equipment and a major portion of the fan cylinder from view. It
also offers a higher degree of protection for operation and main-
tenance personnel.
