UT
Cooling Towers
The UT is an induced
draft, counterflow design cooling tower
with a CTI certified capacity range of
112 to 4,120 nominal tons (493 to 18150
kW). Standard construction consists of
G-235 (Z600-Europe) galvanized steel
with type 304 or 316 stainless steel
available for the basin or the entire
tower. The UT cooling tower comes
standard with the SUPER Low Sound Fan.
Solutions for Sound Sensitive
Applications
The NEW
Ultra-quieT Cooling
Tower comes standard with Super Low
Sound Fan that reduces the overall sound
generated from the top of the cooling
tower. The
Ultra-quieT provides
deep sound reductions and can be used in
combination with Water Silencers to
produce the lowest sound levels
commercially available. Consult EVAPCO’s
iES selection software for unit sound
levels. If a detailed analysis or full
octave band datasheet is required for
your application, please consult your
EVAPCO Sales Representative.
The Super Low Sound
Fan
9 –
15 dB(A) Reduction
versus Model AT Standard Fan EVAPCO’s
Super Low Sound Fan on the
Ultra-quieT tower
utilizes an extremely wide chord blade
design available for sound sensitive
applications where the lowest sound
levels are desired. The fan is one piece
molded heavy duty FRP construction
utilizing a forward swept blade design.
The Super Low Sound Fan reduces sound
levels 9 to
15
dB(A) compared to the
Model AT standard fan.
10
dB(A) decrease is half as loud! The
Ultra-quieT tower is better than half as
loud as other fans!

more information on Sound)
Improved Sound Quality
Emitted Super Low Sound Fan on the
Ultra-quieT Tower!
The SUPER Low Sound
Fan on the
Ultra-quieT tower
reduces sound levels 9-15 dB(A) and
eliminates audible blade passing
frequencies indicative of straight
bladed axial type fans.
Refer to the Narrow
Band Spectrum graph, which indicates
straight bladed axial fans produce blade
passing frequencies – the same phenomena
that produce the signature pulsating
helicopter noise.
The blade passing
frequencies are audible spikes in sound
pressure levels, but are not apparent in
the octave band sound spectrum.
The Super Low Sound
Fan on the
Ultra-quieT cooling
tower reduced sound levels and betters
the sound quality!
Designed for easy
maintenance, the UT cooling tower leads
the industry in service friendly
features. The two most critical areas
for cooling tower maintenance are the
basin and the drive system. The UT basin
section is designed to allow quick and
easy access from outside the cooling
tower. Just like the basin, all service
to the drive system can be safely
performed from the side of the cooling
tower. This eliminates the need to stand
in the cold water basin or add costly
fan deck handrails and safety cages for
routine service to the bearings, belts,
or electrical equipment. Evapco's
Power-Band drive system is the easiest
belt drive system to maintain in the
industry!

The cold water basin
section is easily accessible from ground
level by simply removing the (2) two on
the inlet louver assemblies surrounding
the cooling tower and lifting out the
lightweight louver.
The basin can be
accessed from all (4) four sides of the
cooling tower. The bottom of the fill
section is a minimum of four (4) feet
(1,2 m) above the basin floor. This open
basin design enables the UT basin to be
easily cleaned. |
