An acoustic enclosure for a prefabricated MCC room is an engineered structure that limits noise transfer around a modular Motor Control Center room while keeping ventilation, access and electrical safety intact. This completed project was delivered for Hindalco Industries Ltd. at Lapanga, Sambalpur, Odisha.
Project Overview
The scope covered design, supply and installation of an industrial acoustic enclosure for a prefabricated MCC room inside a heavy industrial facility. It was engineered as one integrated system, not a set of separate acoustic parts.
Client and Location Details
Hindalco Industries Ltd. is the metals flagship of the Aditya Birla Group. Lapanga lies in western Odisha’s industrial belt, where hot summers, heavy monsoon and dust shape material and sealing choices.
Project Requirement
The enclosure had to control noise without compromising electrical clearances, heat dissipation, safe access or emergency exit. It also had to interface with the existing structure, cable entries and site services.
Noise Control Challenge
Prefabricated MCC rooms are built for transport and weather protection, not sound insulation. Lightweight panels resist low-frequency noise poorly, and every ventilation opening, door and cable entry becomes a possible leak path.
Acoustic Enclosure Solution
A prefabricated acoustic enclosure combined sound-insulating panels, treated ventilation paths, sealed acoustic doors and sealed penetrations. Factory-made modules support consistent quality and limit disruption to plant operations.
Design and Engineering Approach
The approach followed a site noise assessment, acoustic panel selection, thermal and ventilation design, structural interface design and a maintainability review. Enclosure practice generally follows guidance such as ISO 15667.
Key Features
- Modular acoustic panels with absorptive infill
- Acoustically treated ventilation paths
- Sealed acoustic doors and cable penetrations
- Weather and corrosion resistant finish
- Maintenance-friendly layout
Materials and Construction
Layered panels use an outer skin, absorptive infill, perforated inner skin and gaskets. Grades and thicknesses are project-specific.
Ventilation and Airflow Considerations
Airflow is sized to the MCC heat load, then treated with acoustic louvers or splitter silencers. Even a small open area can limit overall insulation, so openings are treated carefully.
Acoustic Doors and Access Requirements
Doors use heavy construction with perimeter and bottom seals, positioned for personnel access, equipment movement and emergency egress.
Installation Methodology
Work followed site verification, staging, frame erection, panel and joint sealing, door and louver fitting, penetration sealing and final inspection, all under the client’s safety procedures.
Noise Reduction Objective
The objective was project-specific and set from site conditions and client requirements. No universal figure applies to MCC room enclosures.
Benefits of the Solution
Benefits include a better acoustic environment, clearer communication, maintained cooling, preserved access and support for noise compliance.
Project Outcome
The enclosure was completed and handed over as an integrated noise control solution combining insulation, treated ventilation, sealed access and penetration detailing.
Applications of Similar Enclosures
Aluminium smelters, steel and cement plants, thermal and captive power plants, petrochemical facilities, mining sites and pumping stations.
Why Acoustic Treatment Matters for MCC Rooms
MCC rooms are occupied workspaces. Noise hampers communication, masks alarms and adds fatigue during switching and maintenance. No functional MCC room can be fully soundproof, so the goal is controlled, meaningful reduction.
