Our old Middle Eastern customer, who had previously cooperated with us, signed another order with Dingbo in September, 2025 for 3 sets of 100kw and 1 set of 250kw silent type diesel generator sets, for a total of 4 silent type units. The customer visited our factory last year and immediately signed a contract with us for two 400kw silent type diesel generator sets. After receiving our goods, the customer was very satisfied with the quality and expressed that they would establish a long-term cooperative relationship with us. The customer also kept their promise very well, so this year they signed a new order for 4 diesel generating sets with us. Dingbo has always emphasized that strictly controlling the quality of generator sets is our mission, and we will never ignore any small details that may cause any trouble for our customers.
This order is closely tailored to the climate characteristics of the Middle East region and the actual needs of customers, and has undergone targeted reinforcement design:
100kW Cummins Generator: The core power is the Cummins 6BTAA5.9-G2 engine, a Sino US joint venture, paired with the Shanghai Stamford GR270DX alternator to ensure efficient and stable power output. The control system adopts advanced SmartGen HGM7220N controller to achieve intelligent monitoring and management.

The 250kW Cummins Generator is equipped with Cummins 6LTAA9.5-G1 engine and Shanghai Stamford GR314DX alternator to meet higher load demands, and is also precisely controlled by the SmartGen HGM7220N controller.
Those are generators meet the standard voltage frequency of 400/230V, 50Hz, and are equipped with an 8-hour bottom fuel tank to extend the continuous power supply time and reduce maintenance pressure caused by frequent refueling. The 250A and 630A automatic transfer switches (ATS) equipped respectively can achieve seamless switching between mains power and power generation, ensuring power supply continuity.

The core advantage of this wholesale generator sets is the guarantee of creating value for customers:
Adopting the globally renowned Cummins power system and high-quality Stamford alternators, the design is precise and the manufacturing process is exquisite, ensuring stable performance, low failure rate, and long service life even under long-term and high load operation.

In addition, in response to the climate characteristics of frequent sandstorms and high temperatures in the Middle East, the soundproof box has been optimized by adding dedicated air intakes and installing high-efficiency insect and sand proof filters. This design can effectively prevent sand and dust intrusion, ensuring that the internal cooling and combustion systems of the unit maintain efficient and clean operation in harsh environments, significantly reducing maintenance frequency and costs.
The smooth delivery of the equipment is not only another verification of our company's product quality and customized service capabilities, but also represents the customer's recognition of our products. Thank you for your support!
