Acoustic Enclosure for PSA Unit

Acoustic Enclosure for PSA Unit

Design, manufacture and delivery of acoustic enclosure for nitrogen PSA plant. The PSA plant has a recorded operational noise level of 95dB(A) at 1 metre.  Due to proximity of residential buildings the noise level had to be reduced to below 50dB(A) at the site boundary, approximately 50 metres away.

Design Considerations/Special Requirements:

• Pre-fabricated ‘drop over’ acoustic enclosure, including lifting points to facilitate crane lift.
• Large double sealing double leaf access doors for general maintenance along with removable side panels for major maintenance.
• Pitched roof for water run off.
• Free flow ventilation system comprising of two low level inlets and one high level outlet, all fitted with weather louvres and attenuator pads.
• Enclosure also incorporated an Internal runway beam for heavy lifting.

Performance: The enclosure provided a noise reduction circa 25dB(A) at 1 metre, which corresponded to a noise level well below 50dB(A) at 40 metres and therefore exceeded the customers specifications.
