The Project
Mansfield Pollard’s acoustic experts were engaged to design, manufacture, and install a specialist acoustic enclosure to reduce the noise level of a 4500 kWe TCG 2032B V16 gas engine generator located within a pre-existing, non-acoustic, industrial unit.
Located directly on the roadside in a mixed residential and commercial area, our engineers were tasked to reduce noise levels from 112 dB(a) to 75 dB(a) @1m from the enclosure ventilation inlet and outlet.
As recognised UK leaders in the successful delivery of similar projects, Mansfield Pollard were the standout choice of supplier and worked closely alongside the consultant engineers to design and manufacture a tailor made acoustic solution.
Due to the size and scale of the project, the partnership also worked closely with a team of specialist structural engineers, who designed the load bearing framework to ensure the build would support the outlet ventilation and exhaust systems and integrate three extensive lifting beams.
The Benefits
Effective Noise Control:
Reducing the noise levels from in excess of 130 dBa(a) to 75 dB(a)@1m
Internal Application:
Enclosure designed and built within an existing building
Coastal Protection:
Designed to endure adverse weather conditions
Maintenance Friendly:
With integrated lifting beams, internal gantry and removable walls
The Solution
Working within the constraints of the space and surrounding buildings our engineers designed a bespoke solution to deliver the specified noise levels and ventilation required for the gas engine generator.
Due to the roadside location the acoustic enclosure had to be ultra quiet and suitable for passers-by. A 13 x 7 x 6m highly insulated enclosure was built on-site to provide noise reduction and substantial airflow of 28.55m3/s to cool and ventilate the gas engine generator.
The enclosure was designed with high level inlet and outlet attenuators, overhead silencer, and fully motorised dampers to manage airflow, whilst the forced vent system controlled the pressure within the enclosure.
Due to the coastal nature of the project, specific environmental considerations were implemented within the design. To ensure our solution endures the adverse weather conditions, storm louvres were added to the penthouse outlet.
To aid in the ongoing maintenance of the generator, we built internal gantry within the enclosure which provided an overhead observation area whilst three lifting beams, designed to support 500kg, and a removable 7m x 5m acoustic panel wall enabled any major component removal.
