1.  Adopt the first top Chinese brand engines, alternators and control panels. Second biggest customer for FAWDE.
FAWDE is the NO. 1 engine manufacturer whos is suppling to China First Auto Works for vehicel use such as Audi. FAWDE  has engine agent and service team in many countries, service and spare parts can be guarantteed.  
2. Unique noise reduction technology, noise of silent gensets is only 65dBa at 7 meters.This is a remarkable noise level.  
3. 60 radiator is used on all gensets so they can be used in all weather conditions without power reduction or overheat. This is very important, especially in hot weather areas.


Remember generally people use 40 degree radiator, this is not enough for hot areas. We also use oil cooler for very hot countries.
4. 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. 


Other factories install everything in a single cavity, the engine chamber is very hot during running.
