Internal Plant Acoustic Enclosures

Internal Plant Enclosures

Internally located plant equipment often produces unwanted breakout noise. Acoustic Hardware can provide enclosure to help reduce noise from internal plant equipment such as:

  • Mitsubishi BC Boxes
  • Mitsubishi Lossnay units
  • Daikin BS Boxes
  • Fan Coil Units
  • Refrigerant Switching Units
  • Heat Exchanger Units

Acoustic Hardware designs enclosure to encase the item whilst still allowing penetrations for piped and wired services, and access panels for servicing requirements.

Acoustic Enclosure are made from heavy and sound absorptive materials to reduce unwanted noise and vibration whilst allowing the housed items to maintain normal operating conditions.

How Do I Know If I Need One? 

There may be a variety of cases where an Acoustic Enclosure may be needed. Often the need for an Acoustic Enclosure may be stated as a part of noise control requirements in an acoustic planning report for externally located plant items – Where plant items may be deemed too noisy for the local authority guidelines.
