DG Acoustic Enclosure solutions have become essential for industrial and institutional facilities in India that need to control diesel generator noise while staying compliant with CPCB norms. Ecotone Systems recently completed one such project for Green Power International Pvt. Ltd., a unit associated with the Indian Oil Technology Development & Deployment Centre, at their facility in Faridabad, Haryana.
Project Overview
The client required effective acoustic lining in their DG room to reduce operational noise levels affecting nearby work areas and to meet statutory noise standards under the Central Pollution Control Board guidelines. After a detailed site assessment, our engineering team recommended a customised DG and Turbine Acoustic Enclosure system designed for the specific dimensions, ventilation requirements, and load capacity of the DG room.
Scope of Work
The installation involved acoustic panelling with high-density mineral wool infill, perforated metal cladding, and vibration-damping mounts to reduce structure-borne noise. Special attention was given to the exhaust path, ventilation louvres, and door seals, since these are common weak points where sound leakage occurs even after enclosure installation. The DG and Turbine Acoustic Enclosure was engineered to deliver the recommended insertion loss while maintaining adequate airflow for engine cooling, in line with CPCB’s minimum 25 dB(A) insertion loss requirement for DG sets.
Execution and Results
Our team completed the acoustic lining work within the agreed timeline, with minimal disruption to the client’s ongoing operations. Post-installation noise measurements confirmed a significant drop in ambient sound levels around the DG room, bringing the facility within permissible limits for a work environment situated near office and technical spaces. The client’s maintenance team was also briefed on upkeep practices to preserve the acoustic performance of the enclosure over its service life.
This project reflects Ecotone Systems’ continued focus on delivering practical, code-compliant noise control solutions for industrial clients across North India. Our approach combines acoustic engineering fundamentals with field-tested installation practices, ensuring each DG and Turbine Acoustic Enclosure performs reliably under real operating conditions rather than only on paper.
Conclusion
The successful completion of this DG acoustic enclosure project at Green Power International’s Faridabad facility demonstrates how targeted acoustic lining can resolve noise compliance challenges without compromising equipment performance. For facilities managing diesel generators near occupied spaces, a well-designed enclosure remains one of the most reliable ways to meet regulatory standards while protecting worker wellbeing.
Frequently Asked Questions
What insertion loss is required for a DG acoustic enclosure in India?
CPCB mandates a minimum insertion loss of 25 dB(A) for DG sets, with enclosure or room acoustic treatment designed to meet ambient noise standards where stricter.
Does an acoustic enclosure affect generator cooling or performance?
No, properly designed enclosures include calculated ventilation openings and fans that maintain adequate airflow while still controlling noise.
How long does DG room acoustic lining installation usually take?
Timelines vary by room size and site conditions, but most industrial installations are completed within one to two weeks.
Is acoustic lining a one-time solution or does it need maintenance?
Acoustic panels and seals need periodic inspection, since wear at doors, louvres, and duct joints can gradually reduce noise attenuation.
Can existing DG rooms be retrofitted with acoustic enclosures?
Yes, most existing DG rooms can be retrofitted with acoustic lining and enclosure systems without major structural changes.
