Green Power International Pvt. Ltd. is a well-regarded name in the industrial power and generator services domain, providing comprehensive power solutions to major industrial clients across India. For this project, Green Power International was responsible for the supply, installation, and commissioning of the DG set at the Indian Oil Corporation’s Lube Blending Plant in Palwal, Haryana — a critical petroleum processing and blending facility. As part of delivering a complete and compliant power solution, the client required a custom-engineered acoustic enclosure to control generator noise in line with applicable environmental and industrial standards.

Large industrial diesel generators play a vital role in maintaining continuous and reliable power supply in critical manufacturing and processing facilities. However, high-capacity generators produce significant noise levels during operation that, if left uncontrolled, can result in 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 specifically developed to suit the site conditions, generator specifications, and operational requirements of the Palwal facility.

The Need for Acoustic Enclosures in Industrial Facilities

Diesel generators are widely used across industries as primary or backup power sources. Facilities such as manufacturing plants, pharmaceutical units, petroleum refineries, infrastructure projects, and commercial complexes depend heavily on DG sets for uninterrupted electricity supply. However, high-capacity generators can produce noise levels exceeding 100 dB during operation, creating several significant challenges:

Workplace Safety Concerns

Continuous exposure to elevated noise levels can lead to hearing impairment, fatigue, increased stress, and reduced productivity among workers stationed near or within the generator area.

Regulatory Compliance Requirements

Industrial facilities operating in India must comply with environmental noise regulations and pollution control standards established by regulatory authorities including the Central Pollution Control Board (CPCB) and State Pollution Control Boards.

Environmental and Community Impact

Excessive noise from generator operations can adversely affect nearby communities, residential zones, and surrounding ecosystems — a concern that is especially relevant for industrial plants situated near populated areas.

Operational Efficiency

High ambient noise levels inside facilities can interfere with communication, process monitoring, and equipment operation — ultimately affecting overall plant performance and safety.

To address these challenges, Ecotone Systems designed and installed a robust acoustic enclosure around the diesel generator at the Palwal facility to significantly reduce noise emission while allowing the generator to operate safely, efficiently, and reliably.

Indian Oil Lube Blending Plant, Palwal, Haryana

The Indian Oil Corporation Ltd. (IOCL) Lube Blending Plant at Palwal, Haryana, is a significant industrial facility involved in the blending and processing of lubricant products for various automotive and industrial applications. As one of India’s largest oil companies, Indian Oil maintains high standards of safety, operational efficiency, and environmental compliance across all its facilities.

The Palwal plant operates under strict regulatory oversight, making it essential that all installed equipment — including power backup systems — comply with applicable noise and environmental standards. The installation of a properly designed acoustic enclosure for the DG set was therefore a mandatory requirement for the project to meet IOCL’s facility compliance standards.

Project Scope and Engineering Approach

The project involved a detailed acoustic analysis, customized design development, precision manufacturing, and professional on-site installation of the complete enclosure system. Ecotone’s engineering team began by conducting a thorough evaluation of the generator specifications, site layout, ambient noise conditions, and the required sound attenuation performance levels.

Based on this assessment, a specially engineered acoustic enclosure was developed to significantly reduce noise emissions while ensuring efficient airflow for generator cooling. The following key engineering elements were incorporated into the design:

1. High-Performance Acoustic Panels

The enclosure walls were constructed using multi-layer acoustic insulated panels engineered to deliver excellent sound attenuation performance. These panels feature a heavy gauge steel outer shell, a high-density acoustic insulation core, and a perforated acoustic liner on the interior surface. This multi-layer configuration ensures effective absorption and blocking of sound waves generated by the generator across a wide range of frequencies.

2. Ventilation and Airflow Management

One of the most critical aspects of diesel generator enclosure design is ensuring adequate ventilation. Generators produce large quantities of heat during operation, and without proper airflow management, overheating risks can arise. To address this, the enclosure incorporates engineered airflow pathways and acoustic ventilation systems — including specialized acoustic louvers and airflow channels — that allow sufficient air intake and exhaust while maintaining the enclosure’s sound attenuation performance.

3. Structural Strength and Industrial Durability

The enclosure framework and panel assembly were designed to withstand harsh industrial conditions, including mechanical vibration, thermal cycling, and environmental exposure. The construction incorporates a reinforced structural framework, heavy-duty steel panels, corrosion-resistant finishes, and industrial-grade fasteners to ensure long-term stability and reliability throughout years of continuous operation.

4. Maintenance Accessibility

Generator maintenance is an essential and recurring requirement in plant operations. The acoustic enclosure was designed with strategically positioned access doors and removable panels to allow technicians to inspect, service, and maintain the generator without the need to dismantle the enclosure structure — ensuring minimal downtime and ease of operation.

5. Acoustic Performance Optimization

Through careful acoustic engineering and design optimization, the enclosure minimizes noise transmission from the generator to the surrounding environment. The system is engineered to reduce noise consistently across multiple frequency ranges, ensuring reliable acoustic performance under various generator load conditions.
