The Super Silent 200kVA Prime Power Diesel Generator with Reliable Cummins Engine from Hosem Power is engineered for users who demand strong power performance without compromising noise control. Powered by the robust Cummins 6CTAA8.3-G2 engine, this generator delivers stable 200kVA prime power, making it ideal for industrial facilities, commercial buildings, hospitals, data centers, and residential projects requiring uninterrupted and quiet energy.
What sets this model apart is its super-silent engineering, incorporating multiple advanced acoustic technologies to dramatically reduce operational noise—ensuring quiet, reliable performance even in demanding and noise-sensitive environments.
The entire generator is enclosed within a heavy-duty metal soundproof canopy lined with fire-resistant, high-density acoustic insulation, effectively blocking and absorbing engine noise to keep overall sound levels low.
A specially designed high-efficiency muffler significantly reduces exhaust noise, minimizing the sharp explosive sound typically produced during exhaust release.
Using a labyrinth-style air inlet and sound-damping discharge channel, the airflow remains smooth and stable while ensuring proper cooling—preventing turbulence that could create additional noise.
Heavy-duty vibration isolators are installed between the Cummins engine and the generator base frame, blocking vibration transmission to the canopy and ground, which lowers low-frequency structural noise.
These four systems work together to deliver exceptional noise reduction, making this generator far quieter than standard diesel units in its class.
