Acoustic Enclosures

Our panels and silencers are specially designed by our acoustical engineers, in order to meet all the required attenuation criteria. They are manufactured in our workshops based on your specifications. Our noise enclosures are fitted with SAI-manufactured fans in order to dissipate heat, renew the ambient air and evacuate possible gas leaks. SAI fans and dampers are patented and ATEX certified. SAI noise enclosure design maintains concentration level constant in case of CO2 injection, providing an additional layer of protection against fire or explosion. Access is optimized for maintenance. All of our noise enclosures are also protected against corrosion. Compliant with the toughest contractual expectations, SAI guarantees the acoustic performance of each enclosure. From simple acoustic shields to acoustically insulated industrial buildings, SAI provides complete solutions of all size and shape.

DAS Silencers

SAI DAS silencer’s efficiency relies on taking care of the aerodynamic treatment of the fluid and attenuating part of the noise, thanks to its patented Shock-Less® system. Acoustic noise treatment from special absorbing material selected according to the application. Many options are available : - Outlet elbow - Rain shield - Flanged inlet or BW welded end-piece - Inlet thermal growth compensation - Special painting 20 to 60 dBA acoustic attenuation, allowing for 85 dBA standard residual noise level (1 and 5 meters away from the outlet). Custom-sized, based on the fluid characteristics: nature, temperature, flow, inlet pressure…

Low Frequency Reactive Silencers (SAR-Type)

SAI SAR silencers include several gas relief chambers connected to each other with length-adjusted pipes tuned to the engine fundamental frequency and harmonics. If required, an additional stage can be included for high-frequency absorption. Custom-sized, based on your technical requirements and the fluid and engine characteristics: nature, rpm, temperature, flow, pressure drop, acoustical spectrum… Our SAR silencers can be specifically sized to be integrated to a complete exhaust line: geometry, engine outlet, catalytic equipment… SAI silencers can be used for very low pressure drop and multi-cylinder engines applications (V12, V16, V18…).

Oil mist Eliminators (OME)

Standard: flow ranging from 30 to 3000 m3/h. Custom design available upon request. Many options available. SAI Oil Mist Eliminators reach a 99.9% efficiency on 0.2 µm particles (that are amongst the most difficult to treat and are mostly emitted by rotating machinery). This performance has been certified by the CERM independent lab on aerosols including 80 to 90% 0.2 µm particles. SAI Oil Mist Eliminators are equipped with a patented regulating valve which maintains a constant vacuum in the machine oil tank. Integrated by-pass valve. SAI Oil Mist Eliminator patented technology offers 3 main advantages: 1. Constant vacuum is maintain in the machine lube oil tank regardless of: - Filter clogging - Machine rpm and oil mist flow 2. The Oil Mist Eliminator suction flow automatically adjusts itself to: - Machine-generated oil mist flow - Filtering cartridge remaining service life 3. Significant increase in cartridge service life. Based on the following characteristics: - Air or Gas - Oil or other fluid - Flow Other parameters can affect the design, such as: - Oil (or other fluid) concentration - Specific requirements, such as by-pass, inlet vacuum with or without regulation, gauges (manometers, pressure transmitters…) - Aerosol to vapor ratio (percentage in mass) - Particle size and distribution. Oil tank vents for: - Gas turbines - Generators - Steam turbines - Compressors - Gas and Diesel Engines - Milling machines - Vacuum pump exhaust - Compressors / Chilling Units… SAI Oil Mist Eliminators use high-density fiberglass coalescing cartridges and are compliant with most local regulations.

SVI - Type Low-Output Gas Discharge Silencers

SAI anti-icing silencers include a gas relief module and a diffuser in a single piece of equipment. Amongst their many advantages: - Small envelope - Homogenous diffusion of the fluid at the outlet - No mineral or organic material - Use in high-temperature up to 500°C (932 F) 10 to 30 dBA acoustic attenuation, allowing for 70 dBA standard residual noise level (1 meter away from the outlet). Custom-sized, based on the fluid characteristics: nature, temperature, flow, inlet and outlet pressure… SVI silencers are also available in standard units for flows and pressure up to 300 g/s and 22 b/g.
