B series engine is natural gas engine, Displacements of this engine are 3.9L,5.9L,8.3L,8.9L,13L.Engine power cover from 24kw-450kw. Its advanced economy, power, reliability, durability and environmental security are widely praised by users at home and abroad.


Basic Characteristics of DCEC Serials Diesel Generator Set


All series powered by the Cummins engine, modern technique, dependable performance,high combustion efficiency and low fuel consumption, long time continuous running, long working life, and Easy to maintain. Conform to the standard of IS03046.


All series adopt alternator of Stamford / Marathon/ Faraday/Engga; Excellent excitation characteristics, Ensure that the genset can withstand high power load moment, small Voltage fluctuation, quickly recover. Conform to the standard of GB755,BS5000,IEC34-1,CSA22.2,AS2359.

Controller System

All series use automatic Powertec GC6110 as controller, Integrating digital, intelligent, network technology,use for a single diesel generator set automation and monitoring system,implement a automatic starting/stopping ,the data measured, Alarm protection function of the genset.


Standard 50℃ ambient temperature online radiator, Closed water circulation cooling system, ensure the rated power output of under high temperature environment.

Steel Welding Base shock absorber

Inbuilt shock absorber, perfect shock absorption performance, Easy installation and transport
No need to install shock pad on the connection of base foundation and fixed.
