Noise levels related to diesel generators can usually exceed local codes and city ordinances, not to mention personal comfort levels, deeming noise management a necessity. In a lot of cases, an engine exhaust muffler is the only single form of noise management used to quiet the engine. The engine exhaust is simply one little element of the general noise caused by the generator system. Noise propagates from the engine, generator, radiator fan, turbocharger and also from the muffler casing itself. Varied issues conjointly arise when a large generator also is mobile.
North American Power and Controls a company that is recognized within the trade as a “Generator Packager.” NAP&C combines and assembles all the elements that complete the generator system, together with the engine, generator, fuel system, enclosure, controls, ventilation, acoustics and on this occasion the transport logistics.
Pacific Bell one of NAP&C’s customer’s, a well-known regional telecommunications company uses standby power to provide systems for their switching facilities. The necessity arose for a portable generator to be utilized to maintain power during the period of time the main building’s power was down for construction or in the event of emergency power failure.
The generator was required to be both mobile and quiet, since it would be running near business and residential areas. As a frequent and satisfied customer of Ruskin Sound Control, NAP&C turned to Ruskin to solve their generator acoustic problems. Ruskin has presented in the past a wide array of solutions with similar needs for cooling towers, mechanical plant rooms, pump rooms, tunnel ventilation and parking garage ventilation. NAP&C working together closely with experienced Ruskin engineers, a solution, capable of not only meeting, but surpassing the customers’ performance needs, was meticulously planned and a final design approved.
Ruskin 2″ thick acoustic panels were chosen for the enclosure walls and roof, and because of the dynamic nature of placing an engine in a housing mounted on a trailer, the design team were confronted with many issues not the least of which was the acoustical attenuation prerequisites. Weight and strength constraints were the foremost limiting concern and acoustics became a secondary matter. However, referencing manufacturer’s sound power ratings for the un-enclosed generator model compared to acoustic measurements taken on site utilizing the Ruskin enclosure during actual operating conditions, sound levels were attenuated considerably.
Ruskin offers the most complete line of acoustic louvers / acoustic panels on the market, as well as standard louvers, sightproof louvers, hurricane/wind driven rain louvers, adjustable / operable blade louvers, blast resistant louvers, thinline louvers, drainable and non-drainable louver models, all in a variety of blade combinations including horizontal and vertical.
