When one is looking to reduce the noise of a heat engine at the exhaust, ITS offers complete soundproofing exhaust systems, from the engine output flange, including silencers, bellows, piping elements of the exhaust line, chimney (stack), and, where appropriate: Selective Catalytic Reduction device (SCR).

The soundproofing exhaust systems for heat engines (diesel or gas) marketed by ITS are designed for stationary engines (e.g. generators, emergency units, cogeneration plants) or for fluvial and marine applications of any capacity. They have been developed and tested to make possible their installation downstream of all industrial engines, regardless of their brand and type.

A case-by-case design, taking into account the entire exhaust line with respect to both its acoustic performance and its aeraulic performance allows an overall optimization of the system for compatibility between high energy efficiency and low noise emissions.

Depending on the case, the components of the soundproofing exhaust systems for heat engine may be mild steel or stainless steel. They are designed and built to meet the highest standards of quality and to last a long time.

ITS offers soundproofing exhaust systems for heat engines for the reduction of noise emitted by power plants.

Soundproofing exhaust system for industrial engine, soundproofing exhaust system for genset, soundproofing exhaust system for reciprocating internal combustion engine, soundproofing exhaust system for heat engine: all equipment that one can source from Isolation Technologie Services (ITS).

Soundproofing exhaust systems for heat engines marketed by ITS are meeting the various requirements related to the operation of decentralised power plants.

Firstly, they are allowing to respect the noise level criteria imposed to avoid sound troubles for the neighborhood, when including silencing devices (mufflers) carefully designed to attenuate the exhaust noise, whatever the number of strokes, the rotation speed, the engine size is. In some special cases two silencers are envisaged in series: a primary (reactive) silencer, aiming at the attenuation of low frequencies and a secondary (dissipative) silencer, for which the maximum of acoustic efficiency is for medium and high frequencies. But in many cases, one silencer, combining a reactive chamber and a dissipative stage is envisaged, often when space is limited.

Secondly, they properly treat exhaust gas effluents emissions, to preserve environment from any pollution, by the means of specific devices, based on physicochemical processes.

And, of course those soundproofing exhaust systems for heat engines are making the network allowing the exhaust gas to be ducted from engine outlet towards stack outlet in safe conditions.
