ASI Aeroacoustics has been providing acoustic and aerodynamic (aeroacoustic) products, systems and services since 1972. The ASI Aeroacoustic Chiller/Cooling Tower noise abatement systems require no supplemental air movers, they are 100% passive.

In most installations, chiller/cooler tower performance is enhanced due to improved air flow quality and reduced solar heat gain. Chillers/cooling towers may now be located where they are desired and not relegated to remote locations in order to minimize noise. Sound attenuation may be tailored to individual site requirements - no wasted money!



Chiller Remediation

Measured Noise Reduction of over 31 dBA at 1 Meter Distance and NO air recirculation


Tired of "Band-Aid" fixes to chiller and/or cooling tower equipment that creates high maintenance, air recirculation, higher ambient temperatures, increased power consumption, reduced cooling efficiency, frequent repairs and yields questionable sound attenuation?
