Silencer noise - Import export

Silencers/Mufflers; diesel and gas engine exhaust noise is designed based on required target noise levels and current pressure drop. In addition to the standard silencers for stationary engines, special silencers are designed and manufactured according to customer specifications. In addition to reducing exhaust noise, extremely compact designs are made with the available space in mind.

NR SILENCERAccessories for insulation drying units Admittedly, modern side channel compressors are soundproofed at the best possible rate, however still cause function-related turbine-like noises, often perceived as disruptive by residents. Hence, the use of silent drying units is of little avail. Trotec NR silencers spare your customers unnecessary noise and this way your service will remain in good memory! Marked reductions in noise could be detected during comprehensive practical tests in applications with compressors of leading manufacturers! The universally applicable NR 19 MultiQube is especially suited for use with Trotec insulation drying units of the MultiQube series and provides still more noise reduction without dynamic pressure – With the NR 19 MultiQube, reductions of 14 to 19 dB are possible!

The SLC and SRC rectangular duct silencers reduce the noise level in ventilation and A/C systems. This silencer type is usually installed between a fan and an air supply or exhaust duct, and upstream of air supply vents. All silencers are made of a housing and inner baffles. The housing is made from galvanized steel sheet and its ends are framed with steel sheet angles. All baffles inside the silencer have a round breast at one end and comprise a galvanized steel frame with a soundinsulating insert which absorbs the acoustic energy from the air flow. The soundinsulating insert is a set of nonflammable mineral wool panels. The outer surface of the soundinsulating insert is lined with a special abrasionresistant textile to protect the mineral wool from wear and tear. The mineral wool panels are finished with a glass fibre lining in black; this lining is suitable for systems with a maximum air flow rate of 20 m/s.

Silencers is used to decrease noise level of air flow in the device and systems where air intake and discharge are required. Acoustic and aerodynamic performance of silencer is depended on the dimension, length and form. Pressure loss must be also considered with the acoustic performance in practice. Silencer are composed of metal partitions supported by absorption materials and metal outer case
