Ecotone Systems is proud to announce the successful completion of a high-performance Acoustic Enclosure for a 1010 kVA Diesel Generator (DG) set installed at the Balasore facility of Birlanu Limited (formerly HIL Limited), Odisha. This project reflects Ecotone’s continued commitment to delivering advanced industrial noise control solutions that ensure regulatory compliance, operational efficiency, and a safe working environment.

Large industrial diesel generators play a vital role in maintaining continuous power supply in manufacturing plants and industrial facilities. However, these high-capacity generators produce significant noise levels during operation. If not properly controlled, this noise can lead to workplace discomfort, regulatory violations, environmental disturbances, and long-term operational issues.

Recognizing these challenges, Ecotone Systems designed and installed a custom-engineered acoustic enclosure that effectively mitigates noise while maintaining adequate ventilation, thermal stability, and equipment accessibility. The enclosure was developed specifically to suit the site conditions, generator specifications, and operational requirements of the Balasore facility.

This project highlights Ecotone’s expertise in industrial acoustic engineering, generator noise control, and customized soundproof enclosure design for heavy industrial applications.

Understanding the Need for Acoustic Enclosures for Diesel Generators

Diesel generators are widely used across industries as primary or backup power sources. Facilities such as manufacturing plants, pharmaceutical units, infrastructure projects, commercial complexes, and data centers depend heavily on DG sets for uninterrupted electricity supply.

However, large generators—especially those in the 1000 kVA capacity range—can produce noise levels exceeding 100 dB during operation. Such high noise levels can create several challenges:

Workplace Safety Concerns

Continuous exposure to high noise levels can lead to hearing loss, fatigue, stress, and reduced productivity among workers.

Regulatory Compliance Requirements

Industrial facilities must comply with environmental noise regulations and pollution control standards established by regulatory authorities.

Environmental Impact

Excessive noise can affect nearby communities, residential areas, and surrounding ecosystems.

Operational Disturbances

High noise levels inside facilities can interfere with communication, monitoring, and equipment operation.

To address these challenges, acoustic enclosures are installed around diesel generators to reduce noise emission while allowing the generator to operate safely and efficiently.

Project Overview: Balasore Industrial Facility

The acoustic enclosure installed by Ecotone Systems was designed for a 1010 kVA diesel generator used at the Birlanu Limited manufacturing plant in Balasore, Odisha.

Birlanu Limited is known for its strong industrial operations and commitment to safe, efficient, and environmentally responsible manufacturing practices. The company required a solution that would:

• Significantly reduce generator noise levels

• Ensure compliance with environmental noise standards

• Maintain efficient airflow and cooling for the generator

• Provide easy access for maintenance and inspection

• Deliver long-term durability in an industrial environment

Ecotone Systems worked closely with the client to develop a custom acoustic enclosure solution that met these performance objectives while integrating seamlessly with the facility’s infrastructure.

Key Engineering Considerations for the Acoustic Enclosure

Designing an acoustic enclosure for a 1010 kVA DG set requires careful engineering analysis. Unlike smaller generators, high-capacity industrial generators produce strong sound pressure levels and substantial heat loads.

To address these factors, the enclosure design incorporated several key engineering elements.

1. High-Performance Acoustic Panels

The enclosure walls were constructed using multi-layer acoustic insulated panels designed to provide excellent sound attenuation.

These panels typically include:

• Heavy gauge steel outer sheet

• High-density acoustic insulation core

• Perforated acoustic liner on the interior surface

This multi-layer configuration helps absorb and block sound waves generated by the generator.

The acoustic panels were designed to achieve optimal noise reduction while maintaining structural stability and long-term durability in industrial conditions.

2. Ventilation and Airflow Management

One of the most critical aspects of generator enclosure design is ventilation.

Diesel generators generate large amounts of heat during operation. Without proper airflow, the generator can overheat, leading to performance issues or equipment damage.

To prevent this, the enclosure includes engineered airflow pathways and acoustic ventilation systems. These systems allow sufficient air intake and exhaust while maintaining noise reduction performance.

Specialized acoustic louvers and airflow channels help ensure that ventilation openings do not compromise the enclosure’s sound attenuation capability.

3. Structural Strength and Industrial Durability

The enclosure structure was designed to withstand harsh industrial conditions, including vibration, mechanical stress, and environmental exposure.

The construction includes:

• Reinforced structural framework

• Heavy-duty steel panels

• Corrosion-resistant finishes

• Industrial-grade fasteners and joints

This ensures that the enclosure remains stable and reliable throughout years of continuous operation.

4. Maintenance Accessibility

Generator maintenance is an essential part of plant operations. The acoustic enclosure was designed with strategically positioned access doors and removable panels to allow technicians to inspect and service the generator easily.

This design approach ensures that routine servicing, repairs, and operational monitoring can be carried out without dismantling the enclosure structure.

5. Acoustic Performance Optimization

The primary objective of the enclosure is noise reduction.

Through careful acoustic design, the enclosure minimizes noise transmission from the generator to the surrounding environment. This helps achieve acceptable noise levels outside the enclosure while maintaining safe operating conditions inside.

The acoustic system is engineered to reduce noise across multiple frequency ranges, ensuring consistent performance under various load conditions.

Installation Process

The installation of the acoustic enclosure at the Balasore facility involved several stages.

This information helped define the exact dimensions, panel configuration, and ventilation design for the enclosure.

Manufacturing and Fabrication

After finalizing the design, the enclosure components were manufactured using precision fabrication processes and high-quality acoustic materials.

Each component was produced with strict quality control to ensure accurate fitting, structural integrity, and acoustic performance.

On-Site Assembly

Once delivered to the Balasore facility, the enclosure components were assembled and installed by Ecotone’s experienced installation team.

The installation process included:

• Structural frame setup

• Acoustic panel installation

• Ventilation system integration
