For detailed product specs see our NEW site at http://www.artusaindustries.us IES 2000 Silencers and Sound Attenuators Noise Control for Fans & Exhausts – This specialty product is designed for intake or exhaust fans of large equipment. Large equipment usually requires a substantial amount of airflow but untreated fan areas can create, and even spread, noise unnecessarily. These sound attenuators handle the noise without affecting needed airflow - they are often called silencers.. Silencers normally contain one or more passages which are lined with sound absorbing materials, incorporated in structures that protect them from erosion from air flow. To attenuate low frequency sounds, thick baffles widely spaced are used; whereas for high frequency sounds, the best absorption is obtained by using thin baffles closely spaced. Middle frequency sounds can be absorbed by both thick and thin baffles, but intermediate thickness baffles are preferred. Increased attenuation, at times, may be achieved by incorporating bends or elbows into the silencer.

IES Silencers are custom engineered to provide:
optimum acoustic performance
Acoustical Ventilation Systems
IES engineers design quiet ventilation systems. Quiet ventilation is needed when breakout noise is a problem or when the ventilation system itself is the dominant noise source.
Industrial equipment creates heat build-up inside an enclosure or facility. Channeling air over the equipment supplies cooling and removes heat. Noise from equipment inside the building escapes through openings that intake and exhaust cooling air. These openings must be silenced if it is not to disturb the surrounding environment.
In some cases, the interior of the building is quiet but noise from the large ventilation fans that bring in and expel air is a problem that must be attenuated.
To treat noise breakout or fan noise, we utilize:
AIES builds quiet into turbine intake and exhaust systems as part of our total acoustical facility design, treating intake and exhaust noise with:
Inlet and Exhaust Silencers
IES guarantees the quiet performance of the silencers we supply. Our silencers are tested for various DIL's (Dynamic Insertion Losses) to arrive at the silencer design requirements needed to meet the noise level target while maintaining acceptable pressure drops. We installs:
Air Inlet Filtration
Our acoustical, mechanical and structural engineers can design complete air inlet silencing systems, including filter houses of various configurations.
Duct Sound Abatement
Breakout noise and vibrations from intake and exhaust ducts can be enormous depending on engine size. To treat duct noise,IES offers acoustical:
Gas Turbine Silencers
Once and adequate enclosure is in place the silencing of gas turbine installations in industrial environments is basically a problem of attenuating the noise from the atmospheric inlet and the exhaust openings. In installations in residential and rural areas, the sound from the gas turbine enclosure, auxiliaries, and driven equipment also must be considered in the silencing program. Some degree of attenuation can be attained by natural factors, such as divergence, directivity, air absorption, and duct configurations. Further sound control, however, must be obtained through the use of adequate silencers.
Silencers normally contain one or more passages which are lined with sound absorbing materials, incorporated in structures that protect them from erosion from air flow. To attenuate low frequency sounds, thick baffles widely spaced should be employed for optimal performance; whereas for high frequency sounds, the best absorption is obtained by using thin baffles closely spaced. Middle frequency sounds can be absorbed by both thick and thin baffles, but intermediate thickness baffles are more desirable. Increased attenuation, at times, may be achieved by incorporating bends or elbows into the silencer.
It is important to have experience to determine what combination of absorptive and reactive treatment will most economically produce the required acoustic performance. A turbine exhaust system solution must provide materials and designs that enable highly effective low-frequency noise attenuation and tolerate thermal growth, thus giving long, trouble-free performance. Inlet noise, by contrast, has predominantly high frequency content where an absorptive silencer, in series with the inlet filtration system is required to quiet the turbine. The full system approach--acoustic and aerodynamic--is crucial to optimizing the performance of the turbine and minimizing unnecessary costs. IES uses its proven design, engineering, manufacturing and management experience to provide a seamless package which offers the highest filtration efficiency and the most effective noise control.
IES engineers and manufactures noise control and air filtration solutions for gas-fired turbines and diesel engines that are used for stationary and portable power generation applications. IES has a vast portfolio of successes with applications as small as 100 kilowatts to those as large as several hundred megawatts, and has custom-designed systems installed on all major turbine brands, including GE, Siemens-Westinghouse, Pratt & Whitney and ABB.
