250kW 312.5kVA Cummins Natural Gas Generator Set Open Type For Industrial Power Supply
JFP 250kW / 312.5kVA Cummins Natural Gas Generator Set Open Type With Stamford Alternator
This 250kW (312.5kVA) open-type Cummins gas generator set adopts Cummins electronically controlled spark ignition gas engine matched with genuine STAMFORD brushless alternator, manufactured in accordance with ISO 8528 standards. The unit can utilize natural gas, biogas, landfill gas and other methane-based fuels to provide continuous primary power or emergency standby power. Widely used in farms, sewage treatment plants, landfills, industrial parks, mining areas and distributed energy CHP projects. Open frame design facilitates ventilation, maintenance and flexible layout inside power station.
- Mature matching solution: Cummins dedicated gas engine + Stamford high-quality alternator, stable and low failure rate
- Lower operating cost: gas fuel is more economical than diesel; realize waste energy recycling (biogas, landfill gas)
- Environmentally friendly: low NOx emission, less particulate pollution compared with diesel generators
- High operational flexibility: support island independent operation and grid parallel connection (optional parallel module)
- Strong fuel tolerance, can run on various biomass waste gas after simple purification
- Optional CHP waste heat recovery system to improve comprehensive energy efficiency
- Global service and spare parts support network for Cummins and Stamford
- Factory full load testing before delivery to ensure stable continuous power supply
- Standard Altitude: ≤1000 m above sea level; power derating required over 1000 m
- Ambient Temperature: -10 ℃ ~ +40 ℃
- Relative Humidity: ≤95% (Non-condensing)
- Inlet gas pressure: 2-25 kPa
1. 60Hz / 440V specification can be customized upon request.
2. Gas quality directly affects output power; gas pretreatment system is recommended for biogas/landfill gas.
3. Alternator excitation can be upgraded to AREP/PMG if grid parallel function is required.
