25KW - 28KW Water Cooling Silent Diesel Generator Set with Brushless Excitation Mode
Quick Detail:
Description:
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, TIF<50, THF<2%, IP22.
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.
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.

Competitive Advantage:
1. 60℃ radiator, no overheat would happen in high temperature weather condition. For low temperature area, we add water preheater and oil heater to ensure easy start and good performance.
2. 62 dbA noise level, quiet enough to leave the users and neighbourhood a good living environment.
3. Four-cavity design of genset housing. i.e. engine and alternator cavity, silencer cavity, radiator and electronic fan cavity, battery cavity, the genset can run at very low noise and genset size is quite small. Internal temperature of the genset housing is kept 40-50 ℃, safety is ensured while performance of the genset is maximized.
4. Central AC type cooling fan: 20,000 hours service life, much more than 500 hours as most genset factories use.
5. 2.0mm cold-rolled steel genset canopy: rigid and corrosion resistant.
6. Advanced painting and finishing, no painting colour fade within 5 years.
7. Battery switch to switch off battery when genset is not in use, so no power loss of battery.
8. Fuel non-return valve to prevent fuel returning back to fuel tank and inlet of air to the fuel pipe, so easy start of genset after long time of non-use.
9. Competitive price and fast delivery within 20 working days
10. 15 months or 1200 running hours warranty, whichever comes first.
11. Smallest size and most compact structure, maximum loading and installation space.
12. ISO and CE certificated.
13. All spare parts available.
