Ghaddar Gas Generator DG250 – DG270S (50 Hz) powered by Doosan (Natural Gas)
The above ratings represent the generating set capability guaranteed within ±3% at the reference conditions equivalent to those specified in ISO 8528/1 standard.
Notes
- The applicable voltage range is 380V to 415V for 50Hz applications. For other voltages, please consult factory.
- DG270 (standby power): variable load limited to an annual usage up to 500 hours, of which 300 hours may be continuous running. No overload is permitted.
- DG250 (prime power): variable load and unlimited hour usage with an average load factor of 80% of the prime rating over each 24-hour period. A 10% overload is permitted for 1 hour in every 12 hours of operation.
- DG220 (COP power): is the maximum power available for continuous loads for unlimited running hours a year between the maintenance times recommended by the manufacturer under the environmental conditions.
