Open Frame Three-Phase Generator 500kVA Water-Cooled Factory Emergency Power

We recommend calculating your total load requirement and selecting a generator with a Rated Power that is 10%-20% higher than your actual need to prevent overload. Please send us your equipment list or load details, and our engineers will provide a free, customized sizing solution.

Rated Power (Prime Power) is the continuous output the generator can safely sustain for long periods. Standby Power (Maximum Power) is the peak output for short-term emergencies (usually up to 1 hour). We strictly adhere to ISO8528 standards and guarantee real-rated power without false advertising.

Yes. We offer deep customization based on your local climate. Options include anti-corrosion/salt-spray coatings, extreme cold pre-heating systems, heavy-duty dust filters, and tropical radiators to ensure stable operation in any condition.

Our core engine and alternator come with a 1-year or 1,000-hour warranty (whichever comes first). We provide 24/7 online technical support, comprehensive installation manuals, video training, and a global spare parts supply chain to ensure rapid response.

Our generators feature advanced fuel injection technology, achieving an optimal fuel consumption rate of 190-220 g/kW h. This high fuel efficiency significantly reduces your long-term operational costs and carbon footprint compared to traditional models.
