Genset Sound Enclosures Data Center Noise

Genset Sound Enclosures for Noise Control at Data Centers

eNoise Control can assist you with planning and selection of solutions for data center noise.  Data centers often rely on diesel or gas-powered generator sets (gensets) for backup power. However, these gensets can generate high levels of noise (typically 85–120 dB(A)), which poses challenges for urban installations, regulatory compliance, and occupational safety. Genset sound enclosures are engineered solutions designed to mitigate this noise.Data Center Genset Sound Enclosure

Key Functions of Genset Sound Enclosures

  1. Noise Reduction

    • Enclosures typically reduce noise levels by 25–50 dB(A), depending on their construction.
    • Designed to meet local environmental noise regulations (e.g., 65 dB(A) at 1 meter).

  2. Weather & Environmental Protection

    • Enclosures also shield gensets from weather (rain, dust, heat), enhancing reliability and lifespan.

  3. Safety

    • They offer physical barriers to rotating/moving parts and hot surfaces, improving personnel safety.

Types of Genset Enclosures

  1. Standard Weatherproof Enclosures

    • Basic protection; minimal acoustic attenuation.
    • Ideal for non-noise-sensitive environments.

  2. Sound-Attenuated Enclosures

    • Designed specifically for noise control.
    • Can meet residential or urban noise ordinances.
    • Incorporate acoustic insulation, baffles, silencers, and vibration isolation.

  3. Containerized Enclosures (ISO containers)

    • Modular, transportable units for larger gensets.
    • Easy to deploy with integrated ventilation, silencing, and control panels.

Design Considerations for Data Centers

  • Acoustic Performance: Must meet both day/night zoning requirements and workplace noise standards.
  • Ventilation & Cooling: Enclosure must allow adequate airflow for genset cooling without compromising acoustic integrity.
  • Space Constraints: Enclosures must fit within the facility’s spatial design, including rooftop or basement installations.
  • Maintenance Access: Designs must allow easy access for inspection, maintenance, and fuel refilling.
  • Modular Scalability: Especially important for hyperscale and colocation data centers with expanding needs.

Components of a High-Performance Acoustic Enclosure

Component Function
Acoustic Panels Sound-absorbing foam, mineral wool, perforated steel
Louvers/Baffles Control noise escape through air paths
Vibration Isolators Reduce structure-borne noise
Intake/Exhaust Silencers Attenuate engine air and exhaust noise
Doors/Seals Prevent sound leaks while allowing access

Manufacturers & Vendors

Some of the leading providers of gensets include:

  • Caterpillar (CAT)
  • Cummins
  • KOHLER Power

Compliance Standards

Ensure the enclosure system adheres to:

  • ISO 3744/3746 (Sound power determination)
  • OSHA (Occupational noise exposure)
  • Local building and environmental noise codes
