■ Single Inlet Connection—choose from either side inlet
or bottom inlet connections. All piping from the inlet
connection to the distribution basins is part of the
tower package*.
■ Handrail and Ladder—provides sturdy and stable
access to the top of your tower. Ladder safety cages
and ladder extensions are also available.
■ Access Door Platform—steel structure and bar-grating
attached to and supported by the tower. Full length

■ Motor Location Outside—easily accessible and is not
subjected to the constant humidity that exists inside
the tower plenum. This option uses a Marley full-
floating stainless steel driveshaft.
■ Distribution Basin Dam—allows significant variations
in flow rates while protecting the tower from the
disadvantages of poor water distribution—icing, fill
scaling and erratic performance. Permits the operator
to stage chillers and pumps, and still circulate water
efficiently over all cooling tower cells with the benefit
of dramatically reduced fan hp for a given heat load.
* Standard pipe material is schedule 40 PVC. Steel piping is available as an
option and/or where FM approval is required.
■ Control Systems—ranges in sophistication
from standard fan starters and disconnects to
Programmable Logic Controllers that work in
conjunction with your building or process system.
■ Variable Speed Drive—provides the ultimate in
temperature control, energy management, sound
control and mechanical equipment longevity.
■ Solid State Water Level Control Package—monitor
basin water level with solenoid-valve water makeup.
Configurations include makeup along with high and
low water level alarm and cutoff and electric basin
heater cutoff.
■ Stainless Steel Welded Collection Basin—all collection
basin parts exposed to the circulating water including
structural members projecting into the basin, plus
attaching hardware, and all basin options, including
sumps are heavy-gauge series 300 stainless steel.
Galvanized steel tower option.
■ Stainless Steel Distribution Basins—corrosion is
usually most aggressive in the hot water distribution
basins. Stainless steel provides long, trouble-free
service life. Galvanized steel tower option.
■ Extended Geareducer Oil Line—includes a dipstick to
check Geareducer oil level. Located at the fan deck
level near the side of the tower.
■ Air Inlet Screens—keep leaves and debris out of the
tower with factory-installed, U-edged, galvanized wire
mesh screens over the air inlets.
