Industrial Silencers

	Burgess-Manning Industrial Silencers Founded in 1917 Burgess Manning Industrial Silencers are the industry leaders in noise and pulsation control. Serving the energy industry throughout the world, our wide range of standard and bespoke models control the noise associated with a wide range of industrial processes, including vent and blowdown applications for natural gas, steam, air or virtually any other pressurised gas. Our silencers can provide noise reduction that can exceed 60 dB for some applications. The range of Burgess-Manning Industrial Silencers includes: • Vent and Blow Down Silencers. • Gas Turbine, High Pressure Intake and Exhaust Silencers. • Engine Intake and Exhaust Silencers. • Compressor, Steam and Air Discharge Silencers. • Blower Silencers. • Vacuum Pump Silencers. • Combination Separator/Silencers.
	Quietflo Industrial Silencers The range of products previously offered by Quietflo Engineering Limited has been available as part of the Burgess-Manning range since 1990.

Peerless Research and Development Our constant product improvement uses the latest techniques and makes it possible to reduce the size of our equipment whilst improving performance.
	Product Types Design features of Burgess-Manning vent and blowdown silencers may include single or multiple inlets, multi-stage diffusers, and acoustically lined shells or absorptive panels packed with mineral wool or glass fibre packing. Our latest designs feature "Advanced Micro-Diffusion" which can drastically reduce the silencer size and weight. Silencers may also be equipped with Burgess-Manning's patented "SSF Technology", which effectively eliminates the packing fragmentation and evacuation that can occur in severe service. Typical materials of construction are carbon and stainless steel but materials of higher alloy makeup can be used to provide longer service for applications with high temperature or corrosive environments. Most vent silencers are designed to operate entirely at atmospheric pressure but can be equipped with components designed to maintain back pressure on the incoming flow using accepted ASME design practices. In addition, Peerless offers a variety of standard and custom accessories including supports, weather hoods, bird screens and directional outlets. In addition, Peerless also offers products that combine silencing with other functions such as air filtration, liquid separation, pressure reduction and spark arresting.
	Reactive/Chambered Acoustic barriers within the silencer are used to reflect noise energy back to the source to attenuate low frequency noise. Perforated or slotted baffle tubes connect each chamber for effective broad-band, low-frequency performance. Acoustic performance is a function of overall volume and the configuration of the silencer internals.
	Absorptive/Dissipative Silencer shells are lined with absorptive material to dissipate acoustic energy to attenuate high frequency noise. Typical designs use mineral wool, glass fibre, polyester or metallic scrubble as the absorptive material. Burgess-Manning offers packing that is suitable for Oxygen service and also offers its patented "SSF technology" for severe service.
	Diffuser/Absorptive These systems combine absorptive and reactive designs to cover a broader range of frequencies to improve overall performance.
	Throttling Diffuser/Inhibitive Used to prevent noise in pressure reduction applications typically encountered in vent or process piping systems. Impedance devices are used to dissipate acoustic energy at the source, eliminating the need for additional noise reduction components. Advanced micro-diffusion substantially reduces the size and weight that is normally required using the Absorptive/Reactive approach.
