We are offering engine exhaust silencerall internal combustion engines produce noise, some more or less than the others. The intensity and magnitude of the noise will vary greatly depending upon engine type i.e. Naturally aspirated or turbocharged, horse power developed, means of scavanging, type of fuel used, number of cycles whether 2 cycle or 4 cycle engine etc. Among the pre-dominant sources that makes up the engine noise are the engine intake and exhaust. For the purpose of noise control on engines, it is common practise to use silencers at intake and exhaust for treating the airborne noise. In cases where standard construction silencers do not meet the particular application, the special silencers can be designed to suit specific requirements.

We are offering fan silencersindustrial fan installations, small or large, produce noise. This fan noise is one of the most predominant noise sources in an industrial plant. The magnitude and intensity of noise will vary depending on fan size, horse power, air flow, type and number of blades, static pressure, rotational speed, etc. Fans normally deliver a large volume of air at relatively low static pressures usually measured in inches of water. The rotating action of vanes produce a broad band noise spectrum however, the noise in mid to high frequency range is heard to be louder and requires to be treated for achieving noise control. Generally, silencers are used at intake and discharge of fan installations for treating air borne noise. Fan silencers usually require absorptive type design as they are well known for better attenuation in mid and high frequency range (500-8000 hz). The effectiveness of absorption material progressively reduces at frequencies above and below this range.

Industrial Fan Silencers are installed depending on fan size, horse power, air flow, type and number of blades, static pressure, rotational speed etc. We are named among the renowned Manufacturers, Exporters and Suppliers of Industrial Fan Silencers. The manufacturing of these silencers is done using the latest techniques under the strict vigilance of experts. One can place retail as well as bulk orders for Industrial Fan Silencers with us.

Details :Fan silencers usually require absorptive type design as they are well known for better attenuation in mid and high frequency range (500-8000 Hz). The effectiveness of absorption material progressively reduces at frequencies above and below this range. The noise control is achieved by means of absorption. The acoustic energy propagating through the silencer is effectively absorbed into the fibrous absorption material and converted into heat energy. These silencers generally employ straight thru design and have a low pressure drop as it imposes very little restriction to the flow. The fan silencers are normally selected on the basis of maximum allowable pressure drop at rated flow and the silencing criteria. These silencers are usually sized for around 5000 to 5500 FPM velocity but not exceeding 7500 FPM velocity to prevent excessive self-generated noise and aerodynamic noise generation. While selecting the fan silencer, it must be ensured that the flow area throughout the silencer is sufficient to accommodate the air flow without imposing excessive restriction. Data Required Air Flow Rate (Actual CMH) Temperature (°F) Pressure (PSIG) Maximum allowable pressure drop (inches of water) Existing noise frequency spectrum (63).

Details :

• A vent silencer or a blow off silencer is a device used to reduce unwanted noise created by gas or steam flow in a pipeline discharging directly into the atmosphere.
• This noise can be generated due to the high velocity flow through the valve and turbulence created around any obstacle in the line that suddenly restricts or changes the direction of flow such as valve or an orifice.
• Vent silencers find wide applications in high-pressure vents, steam vents, safety relief valve outlets, system blow downs and purge outlets etc.
• Each vent silencer is designed to attenuate the noise level to the required sound pressure level criteria at a given distance from the silencer.
• In any steam or gas venting / blow off system, the primary release of noise energy occurs at the open stack exit.
• The blow off silencer is installed either within the stack or at the stack outlet to intercept this noise before it escapes into the environment.
• Our vent silencers combine both dissipative and reactive technology in a highly efficient design.
• Data Required Application (Vent, Blow down, Relief Fluid Composition (Steam, Gas, Air) Molecular Weight or Specific Gravity Process conditions upstream of valve and units (lb/hr, SCFM, ACFM), Temperature Pressure (P 1) Atmospheric pressure ( P a ) and temperature (T 2) if known.

Engine Exhaust Silencers that roll off our manufacturing unit are fabricated from premium materials in accordance with the standards. They can be made obtainable in custom specifications, as per the client’s requirements. The quality of these silencers is unsurpassable, making them suitable for a number of applications including diesel generator sets, engine-driven packages, and many more. We are reputed to be among the leading Manufacturers, Exporters, and Suppliers of Engine Exhaust Silencers from Tamil Nadu, India.

Details :

• For the purpose of noise control on engines, it is common practice to use silencers at intake and exhaust for treating the airborne noise.
• In cases where standard construction silencers do not meet the particular application, the special silencers can be designed to suit specific requirements.
• In silencing internal combustion engines, the most widely used silencers are the reactive type, or chamber construction silencers. This type is largely dependent on area change to reflect sound energy back to the source and utilizes the attenuation properties of expansion chambers and perforated tubes.
• The Absorptive-type Silencers covered herein are suitable for almost all the type of engines and operating conditions and provide maximum noise attenuation within the specified pressure drop limitations.
• Most of the naturally aspirated and turbocharged engines are best silenced with these silencers.

We are offering compressor silencer.Centrifugal compressors are noisy and require noise control. Just as a pump raises the pressure on a liquid, a compressor raises air or gas pressure. Centrifugal compressor noise is produced primarily by blade-tip turbulence which is a function of horse power, speed, discharge pressure, piping velocities, number of stages of compression, type and number of blades etc. The high speed rotation of vanes or impellers generates noise which primarily consists of discrete tones interdispersed over a broad-band frequency spectrum of lesser intensity. The maximum amplitude occurs at the blade passing frequency and its second harmonic. The high frequency noise generated is in the audible range and requires treatment for achieving noise control.

The Compressor Silencers that roll off our manufacturing unit are 100% compliant silencers, the design of which is inventive. They are made of high-grade materials and components, in accordance with the standards. We are emerging as the promising Manufacturer, Exporter, and Supplier of Compressor Silencers from Tamil Nadu, India. Besides, we can entertain the demand for customization.

Details :

• The high frequency noise generated is in the audible range and requires treatment for achieving noise control.
• These silencers are absorptive-type silencers that are essentially a high frequency, low-pressure drop attenuator.
• It depends on the sound-absorbing material to dissipate the acoustical energy and is usually straight through designs.
• All silencers should be coupled as close as possible to the compressor to prevent excessive pipe radiated noise.

Silencer Selection :

• The centrifugal compressor silencers are normally selected based on maximum allowable pressure drop at rated flow and the silencing criteria.
• These silencers are usually sized for around 5000 to 5500 FPM velocity but not exceeding 7500 FPM velocity to prevent excessive self generated noise and aerodynamic noise generation.
• While selecting the centrifugal compressor silencer, it must be ensured that the flow area throughout the silencer is sufficient to accommodate the airflow without imposing excessive restriction.
