Overview#
The Blue Star NG600-01 is a 600-kilowatt natural gas / LP standby generator built on the PSI 32-liter V12 platform. It is rated 600 kWe standby on natural gas and 400 kWe on LP at 60 Hz / 1800 RPM. The NG600-01 shares its engine platform (PSI 32L V12) with the NG500-01 and NG650-01, in the same 210×96×103 in OPU footprint. Three-phase only (208V, 240V, 480V, 600V).
Deration profile#
The NG600-01 uses intermediate deration thresholds specific to this output level:
- Temperature: derate 1.5% per 5°F above 87°F inlet air temperature
- Altitude: derate 6% per 1,000 ft above 2,200 ft
This is more tolerant than the standard 77°F / 1,200 ft thresholds, but less so than the NG500-01's exceptional 97°F / 4,200 ft. For high-altitude or high-ambient sites above these limits, consult factory or consider the NG500-01 platform.
Alternator configurations#
| Voltage | Phase | Alternator | Connection |
|---|---|---|---|
| 120/208V | 3 | Stamford S6L1D-C | 12-lead WYE |
| 240V | 3 | Stamford S6L1D-C | 12-lead DELTA |
| 277/480V | 3 | Stamford HCI534E | 12-lead WYE |
| 347/600V | 3 | Stamford HCI534F | 4-lead WYE |
All configurations carry 125°C standby temperature rise and ±0.5% voltage regulation. Note that the 208V and 240V configurations use the S6L1D-C alternator — a different frame than the HCI534 series used at 480V and 600V.
When to spec the NG600-01#
- 500–600 kW standby loads on natural gas or LP (three-phase only)
- Sites where the intermediate deration tolerance (87°F / 2,200 ft) is acceptable
- Applications needing the highest output on the PSI 32L platform before stepping to the PSI 40L (NG800-01)
Our service experience#
The PSI 32L V12 is shared across the NG500/600/650 standby lineup. Service intervals and procedures are the same across this family. The S6L1D-C alternator used at 208V and 240V is a different frame from the HCI534 series — note this when ordering parts or alternator accessories for lower-voltage configurations.
