Low Fuel Consumption Silent Residential Diesel Generators 4 Cylinder Diesel Engine 20KW / 23KW
Quick Detail:


  • Single phase Silent Diesel Generator Set
  • 20KW/ 50Hz, 23KW/ 60Hz. Single or dual AC voltage
  • Driven by powerful Four cylinder Diesel engine
  • Rated voltage: 115V/230V       120V/240V
  • Rated current: 173A/86.9A       191A/95.8A
  • SAIL brand maintenance free battery.
  • Terminal block. Optional ATS.



  • Adopt the first top Chinese brand FAWDE engines, alternators and control panels. Second biggest OEM partner for FAWDE.


  • Sinewave output with distortion ≤5%; Brushless self-excited alternator with auto voltage regulation, H insulation grate, 125 temperature rise, less ±1% steady-state voltage fluctuation, TIF50, THF2%, IP22.


  • Complete display of main parameters and protections on the control panel.


  • Unique noise reduction technology, noise of silent gensets is only 62dBa at 7 meters.


  • The genset housing is separated into several cavities, i.e. engine and alternator cavity, silencer cavity, radiator and electronic fan cavity, battery cavity, so the genset can run at very low noise and genset size is quite small. Internal temperature of the genset housing is kept 40-50 , so safety is ensured while performance of the genset can be maximized.


  • Two big service doors with keys. Auto type door rubber seal strip and high quality noise attenuation sponge and flame-retardant sponge are applied.


  • 60 radiator is used on all gensets so they can be used in all weather conditions, such as tropical and chilly areas.

    Radiator motor for central AC is used for the radiator fan, so the fan can withstand high or low temperature(-40°)and high corrosion environment with service life of 20,000 hours.


  • Big base fuel tank to support continuous running minimum 9 hours at full load.


  • 2.0mm cold-rolled steel for the genset canopy, rigid and corrosion resistant. Painting is by electrostatic spraying, no color difference or fading within 5 years.

Ideal choice of power generating set for residential,commerical use. Low running noise leaves you a peace of mind and enjoyable life.
