    EGSA Publishes Rating Guide for Exhaust Silencers

    by  • March 16, 2015 • General • 0 Comments

    The requirement for low exhaust noise in emergency power systems continues to be a hot topic for facility managers (and code enforcement officials!). In light of this demand, exhaust silencer manufacturers have designed ever-quieter solutions to abate noise, but a lack of consistency has remained in how silencers are rated for sound attenuation performance. The Electrical Generating Systems Association (EGSA), through a newly-published Standard, has now provided guidelines to address this issue.

    If you do design work for commercial facilities, chances are that the architect for your last project gave you very limited space for mechanical and electrical equipment rooms. When specifying equipment such as emergency generators, the equipment footprint is always important. But, what about overhead space for things like the engine’s exhaust system? What are the options when the room’s height appears insufficient?

    Why You Should NOT Rely Solely on Engine Silencer Attenuation Grades.

    by  • October 4, 2011 • FAQ's, General • 2 Comments

    For as long as I can remember, engine exhaust silencer manufacturers have used attenuation “grades” to describe the expected performance of their products. “Critical”, “hospital”, and “residential” are some of the common grades used today. As an attempt to differentiate themselves from one another, silencer manufacturers have come up with new grades such as “super critical”, “super hospital” and even “extreme”! […]
