We design and manufacture engine silencers ranging in attenuation from industrial through hospital grade. Phillips & Temro’s Cylindrical Series Silencers are conventionally shaped cylindrical designs that range in size from 1” up to 48” inlet diameter. While large inlet size silencers are less common, we do have the experience and capability to design and manufacture exhaust silencing systems for some of the world’s largest engines. The “J” Series silencers offer a combination of reactive and absorptive silencing features to offer incremental levels of attenuation.
Phillips & Temro offers a full line of Disk Silencers for enclosed applications where the design offers benefits of internal thermal insulation as well as optimized packaging. Disk silencers are available in critical and hospital grades of attenuation from 4” up to 20” inlet size. These silencers are the preferred choice for packaged power or other applications where space is limited.
We design and manufacture a full range of spark arresting silencers for use in marine, forestry, oil / gas, refineries, and other hazardous environments. These silencers have chamber type designs and are extremely effective in the removal of potentially dangerous incandescent materials. All silencers range in attenuation from industrial through hospital grade. Standard spark arresting silencers are certified to DNV and USDA requirements.
PTI also offers a full range spark arresting silencers type approved in accordance with EN 1834-1:2000, EN 1834-2:2000, EN 1834-3:2000 to comply with ATEX Directive (European Directive94/9/EC) requirements
Low Pressure Drop Silencers
Low Pressure Drop Silencers are available in residential and critical grades of attenuation in standard sizes up to 24” inlet diameter. These silencers are most often used when a low pressure drop is the most important consideration.
These silencers are available in residential and critical grades. Factory customization is also available to fit your specific silencing needs. Cowl® silencers feature a unique single spiral chamber design that allows a free flow of exhaust gas through a uniform cross-section throughout the entire spiral chamber. As the exhaust gases pass through the spiral chamber, exhaust noise is progressively attenuated. The benefits of the Cowl® spiral chamber are high sound attenuation, very low exhaust back pressure, and a very small package size. Typically, Cowl silencers are approximately 1/3 the physical size and ½ the weight of conventional cylindrical silencers no of similar performance.
Cowl® silencers are available in residential and Critical grades. Factory customization is also available to fit your specific silencing needs.
Cowl Silencers feature residential grade attenuation (22 – 28 dB) in sizes from 1” up to 12” inlet diameter. Aluminized steel is standard construction and stainless steel in 304, 316, and 321 grades is available as an option. Cowl silencers are available in several standard inlet/outlet configurations as well as standard choices for various connection types.
Cowl Silencers feature an extended spiral chamber design which results in critical grade sound attenuation performance in the 28 – 33 dB range. The TXS series are also available in several inlet/outlet configurations and various connection types.
The MS Series
Cowl Silencer series that makes installation and mounting easy. Residential grade attenuation (22 – 28 dB) in sizes from 2” up to 6” inlet diameter. Aluminized steel is standard construction and stainless steel in 304, 316, and 321 grades is available as an option. Cowl silencers are available in several standard inlet/outlet configurations as well as standard choices for various connection types.
This is a special Cowl “hybrid” design that combines spiral chamber technology with reactive chamber sound attenuation principles. The result is a super-compact silencer exhibits high performing sound attenuation. MicroDisks are available from 1” up to 2-1/2” inlet size.
