Acoustic, Ventilation & Damper Systems
for Power Infrastructure
KBG Group supplies CPCB-II compliant acoustic enclosures, plant-room ventilation louvers, and fire-rated dampers to power generation facilities, DG installations, and data centre power systems. Proven on Cummins genset installations for hyperscale data centres — engineered for 75 dB(A) compliance without derating the machine.
Power & Energy Challenges We Solve
Power infrastructure lives at the intersection of heat, noise, and fire safety. KBG systems are engineered so noise compliance never comes at the cost of airflow — and airflow never compromises fire compartmentation.
DG Set Noise Compliance
The CPCB mandates that DG sets from 7.5 kVA to 2000 kVA must not exceed 75 dB(A) at 1 metre, with minimum 25 dB(A) insertion loss. KBG acoustic enclosures achieve compliance while maintaining full combustion and cooling airflow — no engine derating, no thermal shutdowns.
Plant-Room Heat Rejection
Power halls and DG rooms reject enormous heat loads. KBG gravity louvers, heavy-duty intake/exhaust louvers, and acoustic louvers deliver the free area the machines demand while keeping rain, sand, and noise out — sized to EN 13030 tested performance data, not guesswork.
Fire & Smoke Compartmentation
Energy buildings are fire-regulated to NBC 2016. KBG UL 555 / UL 555S rated fire and smoke dampers, motorized control dampers, and gas-tight dampers protect duct penetrations through fire-rated walls in switchgear rooms, battery rooms, and cable galleries.
