Silent Diesel Generator Set for Low-Noise Power Supply in Urban & Sensitive Environments

Silent diesel generator sets are diesel-powered systems equipped with soundproof enclosures, designed to reduce operating noise to approximately 65–75 dB at 7 meters, making them suitable for noise-sensitive environments such as hospitals, residential areas, and commercial buildings.

Key Advantages

Selection Considerations

Required noise level (local regulation or project requirement)

Installation location (outdoor / rooftop/ground level)

Ventilation space for enclosure

Load type (continuous or standby)

Multi-Layer Acoustic Insulation Structure

Enclosure uses 50–100 mm composite sound-absorbing materials (foam + steel + damping layer) to reduce airborne noise transmission by 10–25 dB.

Airflow Noise Attenuation Design

Air intake and exhaust paths are designed as multi-bend channels, reducing direct sound leakage while maintaining the required airflow volume for engine cooling.

Integrated Industrial Silencer System

Exhaust system equipped with multi-chamber silencers, lowering exhaust noise without increasing back pressure that affects engine efficiency.

Anti-Vibration Isolation System

Generator mounted on rubber or spring vibration isolators, reducing structure-borne noise and preventing vibration transfer to ground or buildings.
