Exhaust Silencers
ISTIQ Exhaust Silencers are designed to reduce high-level noise generated by engine exhaust systems, especially from diesel generator sets, gas engines, compressors, turbines, and other industrial equipment. Exhaust noise is often one of the most dominant noise sources in a genset or engine installation, and without proper silencing, it can travel long distances and disturb nearby buildings, workers, occupants, or surrounding communities.
A good exhaust silencer must reduce noise without creating excessive back pressure. If the silencer is poorly selected or undersized, it may affect engine performance, increase exhaust restriction, raise operating temperature, or create long-term reliability issues. For this reason, exhaust silencer design must consider the exhaust gas flow rate, temperature, engine capacity, allowable back pressure, insertion loss requirement, frequency spectrum, pipe size, available space, material selection, support arrangement, and installation direction.
Depending on the application, ISTIQ Exhaust Silencers can be designed as absorptive, reactive, or combination-type silencers. The construction may include a heavy-duty outer shell, internal baffles or chambers, perforated tubes, acoustic absorption material, flanged connections, drain points, lifting lugs, support brackets, and suitable high-temperature material or coating. For generator applications, the exhaust silencer is often integrated with acoustic canopies, acoustic shipping containers, genset room noise control systems, exhaust stacks, and flexible expansion joints.
Exhaust silencer performance is not only about reducing the sound level at the outlet. In many industrial applications, the design must also control breakout noise from the silencer body, vibration, thermal expansion, exhaust discharge direction, rain ingress, maintenance access, and site installation constraints. Proper coordination with the exhaust piping layout is important to ensure the system is safe, durable, and practical to maintain.
ISTIQ provides exhaust silencer solutions for generator sets, industrial engines, process equipment, power plants, factories, utilities, data centers, and mechanical services applications. Our experience in acoustic design, fabrication, and installation support allows us to provide practical silencer solutions that balance noise reduction, pressure drop, temperature, durability, and buildability.
For clients who need reliable exhaust noise control without compromising engine performance, ISTIQ Exhaust Silencers provide an engineering-based solution for demanding industrial and generator applications.
