/ The Marley Difference /

Above all, the Aquatower is readily available. You won’t
have to wait around—or accept second best—when you
need a cooling tower. We maintain an impressive stock of
completed towers at our own plants. A growing number of
local distributors can draw from that stock.
Contact your local distributor or Marley representative.
They’ll be glad to help you choose the proper model for
your needs. They can also help you with your layout and
piping.
You’ll enjoy single source responsibility and reliability
because we design and manufacture virtually all major
cooling tower components.
All Marley components are designed and selected to
be a part of an integrated system. For example, the spray
pattern from nozzles and the pressure drop through drift
eliminators both affect a fill’s heat transfer capacity. So, we
include that impact in our thermal analysis.

cold weather.
The thermoformed .4mm thick PVC fill sheets withstand
hot water temperatures as high as 52°C. Fill sheets are
immune to biological and corrosive decay and their flame
spread rating is less than 25 per ASTM E-84. Galvanized
structural tubes support and stabilize the fill. They also hold
the bottom of the fill sheets above the cold water basin
floor to simplify basin cleaning. Removable 25 x 25 mesh
galvanized air inlet screens keep larger airborne trash out of
the collection basin and fill area.

Hot water distribution basin covers are provided as
standard equipment to keep the distribution basin free from
airborne debris and to reduce the likelihood of biological
growth.
All Aquatowers use Marley “Spiral Target” nozzles.
These inert polypropylene nozzles are evenly spaced
thoughout the distribution basin to assure uniform water
distribution over all portions of the fill. Their large openings

■ Cold Water Collection Basin

you ever want to change the design water flow rate.

The Aquatower’s collection basin reduces operating
weight, simplifies basin cleaning, and assures proper
outflow. Water flows from the elevated area under the fill
into the basin’s rear depressed section, where side suction
piping connects. A bottom outlet is also available for gravity
flow applications.
Standard equipment on each tower basin includes:
a screened suction connection; a threaded overflow
connection; a threaded and plugged drain connection;
and a float-operated make-up valve. Models 492A through
496B also include a bottom outlet conforming to flat flange
specification. A blank cover plate is provided to seal the

/ Construction And Components /
■ Mechanical Equipment
Belt-driven propeller fans insure design airflow at
minimum power. Fans are supported by an oil-lubricated
tapered roller bearing assembly with remote oil reservoir.
For ease of maintenance all drive components are
accessible from outside the tower.

■ Hoisting and Handling
Hoisting instructions on each tower explains how to use
a spreader-bar and slings beneath the cold water basin floor
to hoist the Aquatower. The tower’s design also allows easy
handling with a forklift.

■ Safety
Standard Aquatower safety features include fan guards

Caution
The cooling tower must be located at such distance and

ducts. The purchaser should obtain the services of a
Licensed Professional Engineer or Registered Architect
to certify that the location of the tower is in compliance
with applicable air pollution, fire, and clean air codes.

Description

Option

Field Assembly

Where unique space restrictions or
rigging conditions demand, Aquatowers
can be shipped ready for field assembly
by others. Complete step-by-step
assembly instructions are provided.

Stainless Steel
Construction

All Aquatower models are available
with stainless steel structure. Or you
can choose a galvanized tower with
a stainless steel cold water collection
basin. Your Marley sales representative
can help you choose the amount of
corrosion resistance necessary for your
installation.

Control System

Factory-installed control center in
IP55,IEC enclosure mounted on tower
casing. Complete with thermostat controller for single or two-speed motors to
maintain chosen cold water temperature.

Vertical
Discharge
Hood

This option is available on Models 494A
and larger. It provides vertical discharge
of the air leaving the tower. Hoods are
galvanized steel. They ship separately
for installation by others. A large access door provides entry to the fan and
mechanical equipment.
For use in restrictive enclosures or other
site situations where horizontal discharge
is not desirable. CTI Certification does
not apply when this option is selected.
