Industrial silencer

When one is seeking to a noise reduction by the suggests of a silencer, ITS offers a wide range of
industrial silencers for many applications related to acoustic insulation / soundproofing associated for
the protection of workers against noise, the preservation of acoustic environment, the limitation of
noise emissions inside the energy sector, the acoustical behavior of testing rooms, the acoustic comfort
in industrial buildings. Get far more information about engine silencer

Selection of applications
reduction of sound transmission within a duct, a pipe or an opening, with out stopping the fluid
transportation

industrial silencers can be inserted into aeraulics networks, especially for the inlet or outlet of
ventilation or air conditioning systems e.g. climate control, refrigeration, cooling (if expected: with
towers) but also for the soundproofing of fans e.g. oven for heavy business, fumes treatment procedure,
as well as of compressors, of heat engines and combustion turbines (for the diminution of noise emitted
by air intake and exhaust for power generation)

industrial silencers may be inserted into pressurized fluid networks e.g. to limit the noise of control
valves (in-line silencers) or to lessen noise emissions through depressurization (discharge expansion) e.g.
tank drain, bleed, valve

Benefits
outstanding technical traits and robustness

ease of implementation (easy assembly/disassembly)

high adaptability of acoustic efficiency

wide range of probable applications including reduction of noise emitted by gas turbine air intakes, inlet
(resp. outlet) of cooling towers, of cooling systems, of aerocondensers, of chillers, of air conditioners, of
heat pumps ... and noise reduction (notably: mouth noise) of smoke evacuation ducts (stacks, flues for
test rigs, exhaust ducts ...)

Presentation :

envelope generally rectangular (at times circular in case of silencer for air ducting works for instance),
metallic, single or double shell (fantastic mechanical resistance more than time) if essential with an
upstream connecting flange and with a downstream connecting flange and ( for some applications) with
thermal, acoustic or thermoacoustic outer insulation. Plastic building doable for specific applications
(e.g. in case of really corrosive fluid at low temperatures)

splitters (at times referred to as: baffles) normally parallelepipedic (except for silencers having a circular
cross section), with metallic frames and structures. Plastic construction feasible for specific applications
(e.g. in case of very corrosive fluid at low temperatures)

thickness, filling (typically mineral wool: polyester wool or other for specific applications), finishes, free
open location, geometry of upstream and downstream ends: adapted based on the desired
performance
