What insertion loss (IL) do your silencers achieve?

We specify octave-band IL to meet your boundary noise criteria and submit ISO 7235 test data along with pressure-drop calculations at your design airflow.

Will silencers restrict airflow?

We model pressure drop (ΔP) and select splitter geometry to meet both acoustic targets and system ΔP budgets. High-free-area acoustic louvres are used where ventilation is critical.

Do you support rooftop chillers and gensets?

Yes. Solutions include acoustic louvres for façades/screens, fan silencers, and enclosure systems with vibration isolation for standby generators and chillers.

What finishes are available?

Galvanised steel, aluminium or stainless steel with optional PPC coatings; corrosion categories C3–C5 as required.

Data Centre Noise Control — Guaranteed IL, Engineered Airflow

Meet boundary noise limits without compromising cooling or uptime. We design and supply silencers, acoustic louvres, barriers/enclosures and vibration isolation for hyperscale and colocation projects across Southeast Asia.

Solutions for Data Centres

Acoustic Louvres & Screens

High free-area louvres and louvred doors for façades and rooftop plant. Optimised for airflow while delivering certified insertion loss.

Fan & Duct Silencers

Axial/centrifugal attenuators and splitter silencers sized to your duty and ΔP budget, with octave-band IL to meet boundary criteria.

Barriers & Enclosures

Compound barriers and engineered enclosures for standby gensets and chillers, with spring isolation and inertia bases.

Our Process

1. Assess
We review boundary limits, fan schedules (CFM/m³·s), and available footprint.

2. Model
We model octave-band IL and pressure drop to select geometry and finishes.

3. Specify
We issue IL schedules, ΔP curves, corrosion class and submittal package.

4. Supply & Commission
Regional fabrication and install support; verification at SAT.

Specification Text (extract)

Provide factory-tested silencers in accordance with ISO 7235. Minimum octave-band insertion loss to meet site boundary criteria at [nearest receptor]. Submit pressure-drop calculations at design airflow [m³/s]. Construction: galvanised or stainless steel; PPC finish as scheduled; non-hygroscopic acoustic infill with migration control; acoustic louvres to achieve high free area at design face velocity. Vibration isolation: spring mounts with 25–50 mm static deflection as scheduled.
