Noise attenuation

Tartarini Type SRII and SRS silencers ensure more efficient noise abatement for high pressure drops and high gas velocities.

Emerson Process Management has released the Tartarini™ Type SRII and SRS silencer options for the Type FL regulators. These new silencers provide an efficient noise prevention solution for natural gas transmission or distribution installations.   

Types SRS and SRII silencer options are available for DN 25, 50, 80, 100, 150 (1, 2, 3, 4, 6-inch), as well as a new DN 200 (8-inch) size, opening a broader application range for this product family. Noise reduction of up to 20 dB(A) can be achieved, depending on the application. As a source treatment, Types SRS and SRII silencers utilise multiple orifices of special size, shape, and spacing, which reduce noise-producing interactions and offers an alternative to path treatment or buried service. Units already installed can be easily retro-fitted with a Type SRII or Type SRS.
