Yuchai Engine Industrial Silent Diesel Genset 400KW 500KVA With Low Noise Operation

This 400KW (500KVA) silent diesel genset is powered by genuine Yuchai heavy-duty turbocharged & after-cooled industrial diesel engine, matched with high-efficiency brushless synchronous alternator. It adopts heavy-duty fully-enclosed industrial silent canopy together with scientifically optimized multi-layer noise-reduction and circulating heat-dissipation system, delivering stable heavy-load continuous power output with low-noise and low-vibration performance.

Widely used in noise-sensitive large industrial parks, manufacturing bases, data centers, municipal key projects, commercial complexes, high-rise buildings and large hospitals. It can work as long-term prime power supply or critical emergency standby power when mains power fails. Complying with ISO8528 and CE international standards, this Yuchai silent genset features ample power reserve, stable running performance and outstanding cost-effectiveness, providing reliable large-power solutions for global industrial and commercial projects.
