When one is looking to obtain a noise reduction by the means of a silencer, ITS offers a wide range of sound attenuators for industrial chimneys / stacks for all applications related to acoustic insulation / soundproofing related to the protection of workers against noise, the preservation of acoustic environment, the limitation of noise emissions in the energy sector.

ITS offers powerful solutions at a reasonable cost in response to all the needs in the matter of soundproofing (preventive or curative) by the means of equipment (standard or tailor made) for which the quality of design and of execution meets the highest level of requirement in this area for an efficient fight against noise in the context of compliance with legislation on noise at work or of improvement of working conditions.

The sound attenuators for industrial chimneys / stacks offered by ITS allow (depending on the case) to limit noise due to air or gas flue outlet.

The noise level close at hand is generally well below the lower values of exposure of workers to noise trigging action and the noise levels in environment are generally well below the limits imposed by regulations in order to avoid sound nuisance.

They can allways be disinstalled for maintenance actions.

They are usually made of metallic splitters with a mineral fiber filling (and make depending on the case: walls and/or roof of the housing aiming at noise limitation). Some of those construction elements may have an insertion loss Di that can reach 50 dB as a standard for medium high frequency (a higher performance can be obtained by the means of special constructions).

They are generally installed in concrete infrastructures acting as an enveloppe.

Regarding products and construction systems proposed by ITS their performance is measured in laboratory according to the current standard:

  • ISO 7235 Acoustics - Laboratory measurement procedures for ducted silencers and air-terminal units - Insertion loss, flow noise and total pressure loss

The sound attenuators for industrial chimneys / stacks proposed by ITS can be delivered as a kit ready to assemble with assembly instructions or be installed turnkey.

A guarantee of acoustic performance on site is issued for each installation of sound attenuators for industrial chimneys / stacks . The verification can be conducted according to standard NF EN ISO 11820 Acoustics - Measurements on silencers in situ.
