Rated Volatge and Rated Frequency: 380~440V (50Hz), 220~480V (60Hz)
Voltage Stablized Regulation: ≤ ± 1.5%
Frequency Fluctuation Ratio: ≤ ± 1%
Insulation Class: H
Engine Type: Four stroke, electronic control spark plug ignition, water
cooling, premix proper air and gas before combustion
Cooling Mode: Radiator fan cooling for closed-type cooling mode, or heat
exchanger water cooling for cogeneration unit.
Fuel: Natural gas / Biogas
Gas Consumption: 0.3 / 0.6 m3/kWh
Genset working condition:
A. Acceptable working conditions
Ambient temperature: -10~+40ºC
(antifreeze or preheater needed for below 0ºC)
Relative humidity: <90%(20ºC)
Altitude: ≤1000m
B. Normal working conditions
Gas gensets can run at rated power on the conditions:
Atmospheric Pressure: 100kPa
Ambient Temperature: 20ºC
Relative Humidity: 30%
C. Applied gas
Natural Gas, Biogas, LPG, Landfill gas, Oil gas, Syngas, Coal mine gas
Acceptable fuel gas pressure: 5~12kPa
CH4 content: for natural gas ≥ 85%; for biogas ≥ 55%
Gas heat value ≥ 5500kcal/Nm3 (23MJ/Nm3 ).
(Genset output power will increase as the gas heat value increase, if use low heat value gas for fuel (Heat value<5500kcal/Nm3, it will lower the power efficiency.)
