About The Client
Capral Limited, one of Australia’s largest suppliers of aluminium products, faced a challenge at their Penrith facility. Hydraulic and vacuum pumps that operated in an open area were generating consistent, high-volume noise that impacted nearby workers and risked breaching environmental noise regulations.
The Challenge
Hydraulic and vacuum systems are known for their constant low-frequency sound output, which easily travels through industrial spaces and beyond property boundaries. At Capral’s site, this uncontained noise posed two key issues:
- Workplace health and safety concerns related to prolonged staff exposure
- Compliance pressure under EPA regulations governing noise emissions
Capral realised they needed more than just a sound barrier; they needed an engineered acoustic solution.
Our Approach
AcousTech designed a custom acoustic enclosure using the Sonic System acoustic modular panel solution. After a detailed site inspection and client brief, our engineering team developed CAD concepts to suit the new hydraulic pump infrastructure. The design incorporated airflow, personnel access, roof lift-off sections, and compliance with height clearance codes.
Installation of the enclosure was timed to coincide with a planned three-week plant shutdown for the setup of new machinery, ensuring minimal impact to operations.
The Delivered Solution
Capral’s new acoustic enclosure was constructed to the following specifications:
- Size: 7680mm (L) x 4900mm (W) x 3000mm (H)
- Panel system: Sonic System acoustic modular panel – V100 used throughout, with V50 panels on the end wall near pipe discharge to meet space restrictions
- Structure: Custom-designed and fabricated steel frame, supplied and installed by AcousTech
The Benefits for Capral Limited
- Supports EPA compliance
- Improves staff wellbeing
- Minimises equipment fatigue
- Allows seamless maintenance
- Reduces operational interruptions
