• Introduction

The diesel generators are mainly composed of our new-version alternators (made by ourselves, carrying unique designs and innovations with better performances in all aspects comparing to traditional ones from other manufacturers), the diesel engines, and the control units. The voltage can be customized at the request of users. All products are manufactured in the ISO9001 and ISO14001 certified environments, and carry national patents and CE certificate.

With our 30 years experience in design and manufacturing, all the products carry top performances in all aspects comparing to any other manufacturers worldwide. The obvious competitive features include the full reliable automatic functions, the leading electrical performances, the perfect output waveform, the excellent dynamic performance, the advanced electro-magnetic structure, the worldwide lowest working temperature rise and optimized AVR design. These virtues bring the products outstanding functioning, highest reliability and longer service life, suitable for all kinds of applications.
