ENGINE EXHAUST SILENCERS  





Controlling noise pollution from engine exhausts is a priority for many organizations in the power generation market. It is essential that all Power Generation applications have the required noise control measures in place that ensures the facility meets with the relevant noise criterion.

Typical performance of engine exhaust silencers is as follows :
»   Absorptive engine silencer: 15dB(A) to 25dB(A) (type SM15P and SM25P)
»   Reactive and wave phase shift: 30dB(A) to 50dB(A) (type SM30P, SM40P, SM50P)

Key characteristics of IAC Engine Exhaust Silencers

Our exhaust silencers have the following key characteristics and attributes :
»   Specific applications: co-generation, containers, marine, rail, generation unit (backup, primary,      no break)
»   Circular, rectangular, or oval design
»   Diverse material types to suit application
»   Radial or axial intakes
»   To satisfy the current environmental requirement, all silencers can be supplied with catalysts or       selective catalytic reduction (SCR) systems





INDUSTRIAL FAN SILENCERS  





Primary air fans, forced draft fans, and induced draft fans generally require some form of acoustical treatment. Most applications require inlet and/or outlet silencers to meet Noise Standards  and other noise requirements. For continuous exposure, a maximum of 90 dBA is generally specified to avoid hearing damage. When conversation near the fan is desired, levels of 80 dBA and less are often needed.

We designs and manufactures a complete line of silencers for application on all fan types. Computer-enhanced technology developed for fan, turbine, and other air-moving equipment enables Us do offer a cost-effective solution to every fan silencing application.

We  offers four designs, each with unique advantages, depending upon application-specific requirements for octave band attenuation, pressure drop, and space utilization.





AIRINTAKE & DISCHARGE SILENCERS  





Controlling noise pollution for systems that receive air for combustion engines and turbines is a priority for many organizations. It is vital that all Power Generation installations in Plant Rooms have the required noise control measures in place that ensures the facility meets with the internal and external environmental noise criterion.

We provide noise solution for all types of Power Generation equipment that include :
»   Diesel Generators
»   Combined Heat and Power (CHP) systems
»   Gas Turbines
»   Compressors

We offer a full turnkey service or we can integrate with other systems and services such as filtration, selective catalytic reduction (SCR) systems etc.

Applications of Air Intake and Discharge Silencers

We has extensive experience and technical knowledge of air intake and discharge silencers for all types of applications and designs that include :
»   Intake and discharge silencers for cooling and combustion air requirements
»   Smoke and fire extract systems
»   Noise reduction capability from 10dB(A) to 50dB(A)+
»   Rectangular or circular design
»   Special designs for low frequencies noise control e.g. diesel generators
»   Wide range of noise reduction with minimal pressure loss
»   Large thickness panels to ensure low frequencies attenuation.
