Frequently Asked Questions

Common queries about our industrial silencers and manufacturing services.

For a 1250 kVA diesel generator, we recommend a Residential Grade Silencer with an attenuation of 25-30 dB(A) or a Critical Grade Silencer offering up to 35 dB(A) reduction. Our custom-designed silencers ensure low back pressure to maintain engine efficiency while meeting CPCB noise norms.
According to Central Pollution Control Board (CPCB) norms, the maximum permissible noise level for new diesel generator sets (up to 1000 kVA) is 75 dB(A) at a distance of 1 meter from the enclosure surface. For larger sets, specific stack height and attenuation requirements apply, which our silencers are designed to meet.
Residential grade silencers typically provide 18-25 dB(A) of noise reduction, suitable for industrial areas. Critical grade silencers provide 25-35 dB(A) reduction and are essential for noise-sensitive environments like residential complexes, hotels, and hospitals. We also manufacture Hospital grade silencers for even higher attenuation (35-45 dB+).
Back pressure is the resistance to exhaust flow. High back pressure can lead to increased fuel consumption, overheating, and reduced engine life. Bhavani Engineering silencers are precision-engineered to provide maximum noise attenuation with minimum back pressure, ensuring your DG set runs at peak efficiency.
Yes, we have a strong supply network across India. We regularly supply industrial silencers and exhaust systems to major industrial hubs in Maharashtra (Mumbai, Pune, Nagpur), Rajasthan (Jaipur, Jodhpur, Udaipur), and other states like Tamil Nadu and Karnataka.
Our silencers are built using heavy-duty Mild Steel or Stainless Steel with heat-resistant coatings. With proper installation and minimal maintenance, a Bhavani Engineering silencer typically lasts 10-15 years, even in demanding industrial environments.
Absolutely. We specialize in custom fabrication. Our engineering team can design exhaust piping with complex bends, bellows, and supports to fit your specific building layout, ensuring optimal flow and noise control.
We use high-quality Mild Steel (IS 2062) for standard industrial applications and Stainless Steel (SS 304/316) for corrosive environments or marine applications. All our silencers are coated with heat-resistant aluminum paint or epoxy for enhanced durability.
Reactive silencers are best for low-frequency noise reduction (exhaust firing frequency), while Absorptive silencers are better for high-frequency noise (airflow). For comprehensive noise control, we often recommend a Combination Silencer that utilizes both technologies.
Yes, our silencers are compatible with all major DG set brands including Cummins, Kirloskar, Mahindra Powerol, Caterpillar, and Ashok Leyland. We customize the flange dimensions and flow characteristics to match the specific engine requirements.
