UT Cooling Towers

Independently certified to withstand seismic and wind load forces at ALL Building locations in North America. The UT is an induced draft, counterflow design cooling tower with a CTI certified capacity range of 112 to 4,995 nominal tons (493 to 21,960 kW). Standard construction consists of G-235 (Z-725 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! (refer to the Sound Basics section for 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.
