1. Engine (Cummins 6CTAA8.3-G2)
●6-cylinder in-line structure with 8.3L displacement: Ensures stable power, avoids single-cylinder overload, and fits small factory production lines such as powering 3-4 textile looms steadily.
●Turbocharged intercooling system: Boosts combustion efficiency, maintains over 90% rated power at altitudes of 2000 meters and above, and solves power loss issues at plateau construction sites like road construction backup power.
●Direct injection fuel system: Delivers fuel precisely with an error within ±2%, cutting fuel waste. It saves 8-10 liters of diesel per 10 hours of operation compared to old-fashioned mechanical injection generators when used as standby power for a 5-story hotel.
2. Alternator (Matching Configuration)
●Brushless synchronous design: No need to replace carbon brushes, lowering maintenance frequency. It prevents unexpected shutdowns caused by brush wear for data centers, keeping server racks powered 24/7.
●H-class insulation plus IP23 protection: Withstands high temperatures up to 180℃ and blocks dust and light rain. It works reliably when installed in open-air construction sites like bridge construction, without failures induced by dust accumulation or sudden drizzle.
3. Silent & Vibration-Reduction Design
●Fully enclosed soundproof cabinet: Filled with high-density acoustic cotton, keeping noise at 68-75dB(A) at a distance of 1 meter, which is equivalent to normal conversation volume. It fits residential area backup power like community emergency power supply without disturbing residents.
●Rubber vibration isolators: Installed between the engine/alternator and the base, reducing vibration transmission. It won't cause floor resonance or noise when placed on the 2nd floor of a commercial building as standby power for elevators.
