Silencer for supply and exhaust fans
Given the high level of noise emitted by groups of fans and exhaust, there is a need for the installation of noise attenuators at air inlet and outlet points, such as silencers for fans. Isso guarantor that there is a perfect functioning and an increase in the useful life of the assembly.
Noise attenuators, such as silencers for fans, are sized according to the need for power and loss of the load required for thermal change. They can be manufactured with the most diverse types of materials, among them: carbon steel, stainless steel and aluminum.
Depending on the space available and the required dimensions, the noise attenuators can be of the type: lamellar — whose sound attenuation occurs in parallel or concentric lamellae — or of the plenum type — whose sound attenuation occurs by absorption combined with energy variation kinetics.
The same technologies are applied as well as fans and two clinker coolers, characteristics of the cement manufacturing industry.
We give Arbomtec a mission to deliver quality solutions for industrial acoustic attenuation, to guarantee a safe working environment in the operational areas of our customers and greater comfort in the regions inhabited around the industrial units. Our objective is to provide products and services so that our clients comply with current regulations.
Standards such as NR15, from the Ministry of Labor, which establishes the noise tolerance limits in the operating areas of companies, and also ABNT NBR 10.151, which defines the limits of daytime and nighttime noise in regions inhabited by industries.
