When one is looking to obtain a noise reduction by the means of a silencer, ITS offers a wide range of exhaust silencers for reciprocating internal combustion engine for various applications related to acoustic insulation / soundproofing: protection of workers against noise, preservation of acoustic environment, 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.

Theexhaust silencers for reciprocating internal combustion engine offered by ITS allow to reduce the noise due to the discharge of combustion gases from diesel or gas engine and to provide (if required) associated features (such as: spark arrester, pollution control by insertion of a catalytic converter ...) for fixed installations (power plants and sometimes cogeneration units, standby generators: sometimes on platforms at sea, emergency gen-sets) or mobile (ships, locomotives ...).

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 are usually made of metallic casing and internal components made of steel (stainless if requested). Depending on needs, the linings of dissipative silencers are with a mineral fiber filling. Some silencers may have an insertion loss Di that can reach 50 dB as a standard with respect to a noise spectrum with low frequencies (a higher performance can be obtained by the means of special constructions).

In many cases, the required acoustic performance can be achieved by implementing a single muffler (either reactive or dissipative, or combined), higher performance being obtained by combining two (or in cases range: 3) mufflers installed in series.

Regarding silencers proposed by ITS their performance is measured in laboratory according to the current standard:

  • standard NF ISO 6798 Reciprocating internal combustion engine - Measurement of emitted airborne noise - Engineering method and survey method

The exhaust silencers for reciprocating internal combustion engine 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 exhaust silencers for exhaust silencers for reciprocating internal combustion engine .

Exhaust silencer for heat engine, exhaust silencer for reciprocating internal combustion engine, noise reduction device for heat engine exhaust, noise reduction device for reciprocating internal combustion engine exhaust: all equipment that one can source thanks to Isolation Technologie Services (ITS).

Such equipment is necessary because, stationary or embedded, reciprocating internal combustion engine (thermal engine) generate significant noise in the exhaust.

Consequently, they must be equipped with soundproofing devices being efficient and durable (to withstand the high temperature and the aggressiveness of the burnt gases) to limit their impact on the sound environment.
