Catalyzed silencers combine emission control and sound attenuation in a single integrated unit, helping engines comply with both regulatory emissions limits and noise requirements.

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%
