Stainless Steel Options
Stainless Steel Collection Basin:
12.1:
Replace paragraph 12.1 with the fol-
lowing:
The cold water basin shall be
heavy-guage series 300 welded stain-
less steel. Suction connections shall
be equipped with stainless steel debris
screens. A factory-installed, float-oper-
ated, mechanical makeup valve and
waste water blowdown line shall be
included. A 4" (101.7 mm) diameter
PVC drain and overflow shall be provid-
ed in each cell of the tower. The basin
shall include a depressed section into
which accumulated silt can be flushed
to permit cleaning. The basin floor
adjacent to the depressed section shall
slope toward the depressed section to
prevent buildup of silt under the coil
area. All steel items which project into
the basin (coil supports, anchor clips,
etc) shall also be made of stainless
steel.
Stainless Steel Distribution Basin:
9.1
Replace paragraph 9.1 with the
following:
An open stainless steel
basin above the fill with removable
interchangeable polypropylene nozzles
installed in the floor of the basin shall
provide full coverage of the fill by
gravity flow. Basin shall be installed
and sealed at the factory and shall be
equipped with removable, stainless
steel covers capable of withstanding
the loads described in paragraph 5.1.
All components of these basins with
the exception of the nozzles and redis-
tribution piping shall be stainless steel.
9.2
Replace paragraph 9.2 with the fol-
lowing:
A redistribution basin below
the fill with removable interchange-
able polypropylene nozzles installed
in the floor of the basin shall provide
full coverage of the coil at a flow rate
sufficient to ensure complete wetting
of the coil at all times. All components
of the basin with the exception of the
nozzles and ABS redistribution cover
shall be stainless steel.
Q
The cold water basin is the only part of the tower that is subject
to periods of stagnant water, concentrated with treatment chemi-
cals and customary contaminants. It is also the most expensive
and difficult part of any tower to repair or replace. For these
reasons, many customers—particularly those who are replacing
older towers—choose to specify stainless steel cold water basins.
Q
It would also be advisable to change the fill support tubes in
Paragraph 8.1 from galvanized structural tubing to 300 stainless
steel structural tubing.
