Peerless Europe Limited UK - Industrial Silencers(Burgess Manning)
Reactive/Chambered(ok)
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.
Diffuser/Absorptive
These systems combine
absorptive and reactive designs to cover a broader range
of frequencies to improve overall performance.
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.
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.
