    Exhaust silencers

    Technical sound solutions for a reduced noise pollution

    Exhaust silencers

    Effective reduction of sound emissions

    The increased use of combined heat & power plants, biomass plants and modern oil and gas boilers in our immediate living environment is accompanied by an increase in noise pollution. Medium and high-frequency noises from modern condensing boilers and fans as well as low-frequency humming from CHPs are perceived both in the home and often in the surrounding area. Jeremias has been developing active technological sound solutions that effectively reduce such noise pollution for many years.

    We offer the following types of exhaust silencers:

     

     

    Absorption silencer (ASD/AED)

    These passive silencers use porous material such as mineral wool to achieve attenuation mainly in a medium and high frequency range. Any acoustic energy is absorbed by friction effects on the wool and transformed into heat.

    Acoustical Silencing Lenght (ASL)

    These absorption silencers use porous material such as mineral wool to achieve attenuation mainly in a medium and high frequency range. Any acoustic energy is absorbed by friction effects on the wool and transformed into heat.

    Combined exhaust silencer (KSD/KED)

    This type combines an absorption silencer with several resonance chambers for the additional attenuation of lower frequencies. Each of the chambers is responsible for filtering out a specific frequency range which leads to a broadband attenuation of the noise.

    Noise insulating cores (SDK)

    Noise insulating cores are predominantly designed for retrofitting in chimneys and contribute to effectively reducing noise peaks according to the principle of absorption. They are suspended from above and easily to install.
