Catalyzed Silencer
Catalyzed silencers combine industrial emissions control and sound attenuation in a single integrated unit, delivering exhaust silencing and aftertreatment in one assembly. Ideal for power generation, gas compression, and continuous-duty industrial applications, they help engines comply with both regulatory emissions limits and noise requirements without the footprint of separate catalyst and silencer systems.
Where They’re Used
Power Generation
Pumping
Gas Compression
Other continuous-duty industrial applications where quiet operation and regulatory compliance are required, especially in space-constrained and retrofit installations
Benefits
Dual functionality: emissions reduction + noise control in one assembly
Compact design ideal for enclosures, retrofits, or mobile equipments
Lower installation complexity compared to separate catalyst and silencer units
Reduced maintenance with fewer components
Consistent performance across a wide range of operating conditions
Serviceable for long-term reliability
When a Catalyzed Silencer is Needed
To Meet Emissions and Noise Regulations: Required where local, national, or permit limits restrict NOx, CO, HC, PM, or noise levels
For Engines Operating Near People or Sensitive Sites: Hospitals, commercial facilities, schools, and urban installations benefit from odor, particulate, and noise control
For Continuous or Prime Power Operation: Ensures compliance and quiet operation during extended duty cycles
When Space or System Integration is Critical: Combines two functions in one unit, minimizing footprint and simplifying installation
Typical Reductions
NOx: up to 90-95% (engine and operating condition dependent)
CO: up to 90%
HC: up to 90%
Sizes
Available in multiple sizes, configurations, and attenuation levels, GT Silex catalyzed silencers can be tailored to meet specific noise, emissions, and packaging requirements. Our engineering teams provide support for sizing, integration, and system layout to ensure dependable performance and long-term durability.
