PRODUCTS DESIGNED TO EXCEED MOST CUSTOMERS NEEDS…

• Compact Light Industrial Grade Silencers (Typical Attenuation of 13 - 19 dBa)
• Industrial Grade Silencers (Typical Attenuation of 14 - 20 dBa)
• Residential Grade Silencers (Typical Attenuation of 19 - 25 dBa)
• Critical Grade Silencers (Typical Attenuation of 25 - 33 dBa)
• Super Critical (Hospital) Grade Silencers (Typical Attenuation of 32 - 40 dBa)
• Extreme Application Grade Silencers (Typical Attenuation of 45 - 52 dBa)
• Spark Arresting Silencers, Turbo Silencers, & Vent Silencers (Typical Attenuation of 12 - 38 dBa)

• Compact, Slim Line, SLR and "H" Series Silencers:  Used for tight spaces. - The balanced combination of resonator chambers, diffusers and acoustical/thermal insulation help to achieve targeted sound pressure objectives.  These low profile silencers are designed for power modules, drop-over enclosures, marine engine rooms and other space-limited applications.
• “Cool” Silencers with 1 inch or “Super Cool” and "H" Series come with 2 inches of internal insulation
• Oxidation Catalysts, Particulate Traps, SCR & Catalytic Systems
• Custom Built, Special Silencer Systems
• Their advanced designs provide high sound attenuation and the benefit of providing optimum sound attenuation in the smallest package.  

“SLIM LINE SERIES”  (Pancake or Hockey-Puck) style of silencers.  This exclusive design provides you with the optimum noise reduction, and a reduced Genset package.  We eliminate the bulk associated with standard reactive silencers.  The 401 series of silencers is now available in 3 distinctive styles: Standard has no internal insulation, “Cool” Silencer has 1” of internal insulation, and the “Super Cool” has 2” of internal Insulation.

The “SLR SERIES”  (Race-Track) and “SLIM LINE SERIES” (Pancake or Hockey-Puck) style of silencers have a unique construction, which can include 1” or 2” of thermal acoustical insulation in the shell.  A reduction of the shell temperature enhances SAFETY to personnel, reduces the ambient air drawn into Radiator, and lessens the wear on electronics exposed to the extreme temperatures around the engine.  The Slim Line 401 series, SLR 501, and "H" series silencers excel in Generator set & Pump enclosures, small rooms, Marine, and Industrial applications were size and temperature is a major concern.

The “COOL” SLIM LINE, SLR, and "H" SERIES contains insulation to significantly lower the exterior body temperature. Two models are now available, the “Cool” Silencer has 1” of internal insulation, and the “Super Cool” and "H" Series has 2” of internal Insulation.  (The Super Cool and "H" series contains a similar insulation thickness to GTE’s old Cool model).

The unique construction of the “COMPACT SERIES” of silencers includes ½” of thermal acoustical insulation in the shell which will provide 300° to 400°F reduction in the skin temperature.  The Compact Series excels in Marine, Industrial, and Generator set enclosure application. 

SILENCER NOTES: If specific sound attenuation is required on any project, GTE's engineers are happy to provide a written guarantee. Many variables can influence the calculated attenuation results that are NOT factored into most software programs and should be looked at during the engineering analysis.  Some of these variables include: variations between engines and testing conditions, ground elevation and atmosphere conditions, exhaust attachment configuration, ambient or background noise, environmental landscape, excessive velocity, mechanical noise, multiple engines.  Ambient noise levels are typically around 65dB, Treated noise levels below that are not practical.  For most applications, it is recommended that the silencer be mounted with at least a 3" clearance between the ceiling and walls.  Excessive and/or standard temperatures, which emanate from the exhaust system components may damage or destroy nearby flammable materials, which may warrant additional clearance or protection. Caution should also be taken around wiring & sprinkler systems. 

Silencers are heavy and typically should not be connect directly to the engine exhaust outlet or turbo. Flex, Wye, or Bellows Connectors allow for thermal expansion and isolates vibration between the engine and exhaust system.  Silencers should be securely mount using brackets or hangers designed to safely support their weight. All exhaust piping into and out of the silencer must be allowed to freely expand and not be allowed to put stress on the Silencer or it’s flanges.  Wall or roof thimbles conforming to NFPA must be used for any exhaust piping that passes through any combustible wall or roof.   Most silencers are supplied with a drain port, and the customer is encouraged to use a rain cap or rain bonnet on the outlet to prevent rain from entering the silencer. Exhaust piping should project upwards for best sound reduction and the use of a rain cap or rain bonnet is recommended to keep moisture out of the silencer and engine.  The standard Painted finish is high heat black. All dimensions are inches.
