8.0 Drift Eliminators:
8.1 Drift eliminators shall be PVC, triple
pass and shall limit drift losses to no
more than 0.005% of the design water
flow rate.
9.0 Hot Water Distribution System:
9.1 A pressured spray system shall distrib-
ute water evenly over the fill. Header
box shall be steel and branch arms
shall be PVC with polypropylene spray
nozzles attached to the branch arms by
an integral screw connection for ease
of removal and cleaning. The spray
system shall provide full coverage
of the coil at a flow rate sufficient to
ensure complete wetting of the coil at
all times.
10.0 Casing:
10.1 The casing shall be heavy gauge G-600
galvanized steel and shall be capable
of withstanding the loads described in
paragraph 5.1.
11.0 Access:
11.1 A large galvanized, rectangular access
door shall be located on both end
panels for entry into the cold water
basin. Rectangular panels are shall be
provided for access to the fan plenum
area to facilitate inspection and allow
maintenance to the fan drive system
12.0 Cold Water Collection Basin:
12.1 The collection basin shall be heavy-
gauge galvanized steel and shall
include the number and type of suction
connections required to accommodate
the out-flow piping system shown on
the plans. Suction connections shall be
equipped with debris screens. A fac-

debris and silt which may accumulate.
13.0 Warranty:
13.1 The MC Fluid Cooler shall be free from
defects in materials and workmanship
for a period of eighteen (18) months
from the date of shipment.
■ Drift rate varies with design water loading and air rate, as well as drift
eliminator depth and number of directional changes. The indicated
rate of 0.005% is easily achievable without premium cost. If a lower
rate is required, please discuss with your Marley sales representative.
■ The combination of PVC piping and polypropylene nozzles is very
resistant to the build-up of scale and slime.
■ The MC fluid cooler design offers side-suction as standard. Bottom
outlets may be supplied to accommodate a variety of piping schemes.
Unless so specified, the fluid cooler you may be asked to approve
may only be available with one type of suction connection requiring
you to redesign your piping layout.
The sloping floor and low-level drain is valuable because it provides a
way to achieve flush-out cleanability.
