A Chongqing Cummins Generator Set is a diesel generator powered by engines manufactured by Chongqing Cummins Engine Co., Ltd. (CCEC) — a Sino-US joint venture established in October 1995, located in Shapingba District, Chongqing, China. The venture is co-owned equally by Chongqing Mechanical & Electrical Co., Ltd. and Cummins China Investment Co., Ltd. These industrial generator sets cover a power range of 200 kW to 1,200 kW, making them a preferred choice for heavy-duty industrial power solutions worldwide.
Chongqing Cummins Engine Co., Ltd. primarily produces three engine series — M, N, and K — all designed for generator set applications. These engines are available in multiple configurations including in-line 6-cylinder, V-type 12-cylinder, and 16-cylinder layouts, with displacements of 14L, 18.9L, and 37.8L respectively.
| Series | Configuration | Displacement | Power Range |
|---|---|---|---|
| N Series | In-line 6-cylinder | 14 L | 200 – 400 kW |
| K Series | In-line 6 / V12 | 18.9 L | 300 – 700 kW |
| M / QSK Series | V12 / V16 | 37.8 L | 700 – 1,200 kW |
The KTAA19-G5, one of the most widely deployed models in the K series, delivers 450 kW with a self-starting and self-stopping mechanism. It can supply rated power to critical loads within 30 seconds of a mains failure, and automatically resumes standby mode with a cooling delay once utility power returns.
The reputation of the Cummins diesel genset in industrial markets is built on four measurable strengths:
Global Service Network. Cummins maintains over 500 distribution agencies across more than 190 countries and regions, giving buyers reliable after-sales support regardless of project location — a decisive advantage for export projects.
High Reliability and Long Service Life. CCEC engines are engineered for continuous operation in demanding environments including mining, telecommunications, construction sites, oil fields, hospitals, and highway infrastructure. Their low failure rate translates directly into reduced maintenance costs over the equipment lifecycle.
Compliance with International Standards. Chongqing Cummins generator sets conform to ISO 3046, ISO 4001, ISO 8525, IEC 34-1, GB1105, GB/T 2820, VDE 0530, and YD/T502-2000 for telecommunications applications.
Investment Scale. Cummins has invested over USD 140 million in its China manufacturing operations, enabling CCEC to maintain Cummins' globally unified quality standards within a cost-competitive Chinese manufacturing base.
Buyers frequently confuse the two Chinese Cummins manufacturing entities. Here is a clear comparison:
| Feature | Chongqing Cummins (CCEC) | Dongfeng Cummins (DCEC) |
|---|---|---|
| Engine Series | M, N, K, QSK | B, C, L |
| Cylinder Config. | 6-cyl inline, V12, V16 | 4-cyl inline, 6-cyl inline |
| Displacement | 14 L – 37.8 L | 3.9 L – 8.9 L |
| Power Output | 200 kW – 1,200 kW | 24 kW – 220 kW |
| Best For | Large industrial / data center | Commercial / light industrial |
For projects requiring above 200 kW — such as data centers, mines, offshore platforms, or large construction projects — the Chongqing Cummins (CCEC) range is the correct specification. For smaller commercial standby applications, a Dongfeng Cummins Diesel Generator in the B or C series is more economical.
Manufacturers and OEM generator set factories in China build the following configurations around CCEC engines:
Open-Type Generator Set: The standard frame-mounted configuration for indoor installations with existing acoustic enclosures or machine rooms.
Silent Diesel Generator Set: Fitted with a heavy-duty acoustic canopy using perforated interior panels for noise reduction, fire prevention, and weather resistance. Suitable for residential-adjacent sites or noise-regulated industrial zones.
Super Silent Generator Set: Custom-engineered canopy systems capable of achieving noise levels at or below 60 dB at 1 meter distance. These units are designed case-by-case for the most demanding acoustic requirements.
Containerized Generator Set: Housed in a standard ISO shipping container for rapid deployment, easy transport, and site security.
Trailer and Truck-Mounted Units: Mobile generator sets for rental markets or construction projects requiring frequent relocation.
High-Voltage and Parallel Units: Configured for large grid-support or data center applications requiring multiple generators operating in synchronization.
The 260 kW Chongqing Cummins generator set is a widely specified model for mid-scale industrial power. Typical technical parameters at 50 Hz are as follows:
| Parameter | Specification |
|---|---|
| Engine Model | CCEC NT855 / KTA19 Series |
| Rated Output | 260 kW / 325 kVA |
| Frequency | 50 Hz (60 Hz available) |
| Rated Voltage | 400 V / 230 V |
| Power Factor | 0.8 (3-phase 4-wire) |
| Speed | 1500 RPM (50 Hz) |
| Alternator Options | Stamford, Leroy Somer, Marathon, Mecc Alte |
| Controller Options | Deepsea, SmartGen |
| Fuel Tank | 8-hour capacity steel base tank |
| Alternator Protection | IP23, Class H insulation |
Industrial reliability depends on automatic protection. Chongqing Cummins generator sets are specified with the following alarm and protection functions as standard:
High and low oil pressure alarm, engine overspeed and underspeed protection, high coolant temperature shutdown, high and low battery voltage alert, overload protection, short-circuit protection, ground fault protection, and generator winding temperature alarm. Control interfaces include panel start/stop, remote control start/stop, and RS485 digital communication for SCADA or building management system integration.
The power range and reliability profile of Chongqing Cummins diesel gensets make them the standard choice across a broad range of sectors:
| Industry | Typical Use | Recommended Configuration |
|---|---|---|
| Data Centers | Emergency standby and prime power | Parallel high-voltage units |
| Mining | Continuous prime power at remote sites | Open-type or containerized |
| Telecommunications | YD/T502 compliant standby power | Silent diesel generator set |
| Hospitals | Critical load backup within 30 seconds | Auto-start with ATS |
| Oil and Gas | Offshore and onshore power supply | Marine or industrial genset |
| Construction | Temporary site power | Trailer or truck-mounted |
When sourcing a Chongqing Cummins genset from a Chinese generator supplier or OEM diesel generator manufacturer, confirm the following before purchase:
Engine authenticity — request the CCEC engine serial number and verify it against Cummins' official records. Confirm the alternator brand is a genuine Stamford, Leroy Somer, or equivalent rather than an unbranded substitute. Check that the controller (Deepsea or SmartGen) is the genuine unit with the correct firmware. Request factory test reports showing load bank testing at 100% rated output for a minimum of four hours, and confirm that export documentation includes the relevant ISO and IEC compliance certificates.
Wholesale diesel generator pricing from China generator factories is typically 15–30% below equivalent European-assembled units at equivalent power ratings, reflecting lower labor costs without compromising on CCEC engine quality, which is manufactured to the same Cummins global standards as any other Cummins facility worldwide.
