The Challenges
As an industry leading acoustic solutions provider, our experts were engaged to design, manufacture and install an acoustic plant room enclosure, with integral exhaust system and attenuation, to reduce the noise of a Volvo TAD733GE back up diesel generator.
Located within a residential building, it was essential that our engineers achieved a reduction in noise levels to 65dB(A) @1m from the exhaust silencers and 55dB(A) @ 1m from wall mounted inlet attenuator and canopy mounted outlet attenuator
The Solutions
With limited access and available space within the plant room, the perfect solution was our unique ALX modular aluminium enclosure, with separated frame and individualised double skin acoustic panels, to house a diesel standby generator and deliver on both specified noise reduction levels.
Access doors were incorporated into the design to facilitate future maintenance of the generator, while our high-specification acoustic panels were designed to be removable to provide additional access to the gen-set.
Due to inconsistencies within the plant room floor the enclosure was constructed on a neoprene bed to minimise any noise leakage.
A steel silencer system, comprising of a heat resistant primary and secondary exhaust silencer, utilised the existing ceiling strutwork and the extended tailpipe terminated through the plant room wall.
The necessary cooling was provided by free-flow ventilation, driven directly from the generator with airflow regulated through remote cooling air inlet attenuator and the roof mounted outlet attenuator.
