Exhaust Fan Discharge Silencers
KNC model VCS, standard, circular silencers constructed of 16 gage, solid, outer skins, 22 gage, perforated, inner skins were supplied. Iron ring flange connections mated the silencers with the exhaust fans. The silencers are cost effective and backed by KNC’s extensive, independently tested database and years of proven performance.
KNC model STL-4, NOISEBLOCK™, a 4-sided sound barrier wall system designed from base-plate upward was offered to attenuate the noise propagating from the up-blast chiller. Included in the system was a personnel access door with panic passage hardware, STL-4 panels, trim, structural steel components, copy of structural calculations and P.E. stamped, piece-marked installation drawing set.
Acoustical Wall Hoods
KNC offered custom model VES, dissipative, elbow silencers with iron ring flanges and bracing to attenuate the wall mounted exhaust building ventilation. This controlled noise generated inside the building by the baking processes as well as that generated by the propeller fans venting the building exhaust and make-up air.
By offering a phased solution KNC and their local representative helped the customer meet the required sound levels. Analysis showed a phase approach was an effective solution and saved the customer 60% in cost.
