B&W Universal Acoustic Silencing

Acoustic Silencing
Your World. Clean. Quiet. Safe.

B&W Universal Silencer

We Have Your Acoustic Solutions

Gas turbines and diesel engines have increased dramatically in size and output over the years to meet growing energy demand. To meet the rigorous noise and emission requirements associated with these larger systems -- and protect plan personnel while maintaining optimal performance from their equipment  -- power generation engineers look to B&W Universal for proven, effective solutions. 
 
With more than 50 years of global experience in providing acoustic products and services for industrial, power generation and oil & gas facilities, B&W Universal is uniquely qualified to deliver custom-engineered silencing solutions that meet safety, environmental and efficiency goals.
 
With our high-quality, high-performance silencing components, including inlet systems, and exhaust silencers, B&W Universal can engineer, design, build, deliver, install and service the key components of a complete turbine or engine silencing solution. 

Absorptive Silencers   

B&W Universal Absorptive Silencers
Absorptive silencers are very effective on high noise frequencies (500-8,000 Hz). At frequencies above or below this range, attenuation performance progressively diminishes. Since noise is absorbed by the packing material, absorptive silencers do not rely on internal baffles, tubes or other restrictive devices to achieve noise reduction. Consequently, absorptive silencers generally employ a “straight-through” or similar internal designs that cause minimal air flow restriction.

Blower Silencers

B&W Universal Blower Silencers
Blower silencers are required in many applications such as industrial processing and wastewater treatment. With a resume that includes hundreds of thousands of blower silencers sold to date, B&W Universal is an industry expert in meeting blower silencing needs.

Engine Exhaust Silencers and Systems

B&W Universal Engine Exhaust Silencers and Systems
B&W Universal's exhaust silencers provide the best performance for all engine applications. We offer silencers crafted for four different attenuation grades, and in a variety of styles and configurations, including spark-arresting silencers for gas engine applications. Engine packagers in power generation, oil & gas, and OEM markets look to B&W Universal to provide custom or standard engine silencers that yield excellent sound attenuation.

Vacuum Pump Liquid Silencers

B&W Universal Vacuum Pump Liquid Silencers
B&W Universal’s separator-silencers are used to remove liquid from gas flow vacuum systems using either liquid-sealed rotary positive blowers or liquid ring vacuum pumps. Separator-silencers may be required for both the inlet (vacuum) and the discharge (atmospheric) of a vacuum system. Only the most stringent acoustical environments require significant inlet silencing. An inlet separator provides corrosion protection for the vacuum pump by removing most, if not all, of the process liquid before it enters the vacuum pump. The vacuum pump or blower discharge is normally extremely noisy and requires a high-performance separator-silencer.

Vent Silencers

B&W Universal Vent Silencers
Vent silencers are used in conjunction with systems that utilize a pressure relief valve (PRV). Typical applications for vent silencers are in oil & gas, industrial and chemical processing, heat recovery systems and steam boilers. B&W Universal’s vent silencers are used around the world in many applications. We have particular expertise as a supplier of steam vent silencers for industrial applications and blowdown silencers for gas compression stations.

HV Series vent silencers effectively silence high-velocity air, steam and gas vents, and blowdowns to atmospheres in which sonic or critical conditions exist in the valve. Typical applications include steam boiler relief valves, superheater header relief valves, boiler startup and purge high-pressure air vents, natural gas blowdowns, switch valves, compressor blowoffs, autoclaves and steam ejectors.

Gas Turbine Inlet/Exhaust Systems

B&W Universal Gas Turbine Inlet/Exhaust Systems
A gas turbine is a substantial capital investment. Protection of the turbine begins with air filtration and ends with the exhaust system. However, there is a precious balance between air filtration, noise reduction, emissions treatment and turbine efficiency. Our qualified team of engineers and system experts are available to balance your air filtration and acoustic treatment, and achieve optimal turbine performance.
