Key Benefits
- Turbocharged & Aftercooled induction with water cooling keeps charge temperature under control in continuous duty.
- Dry weight 1410 Kg and envelope 1980mm*900mm*1600mm are published so the installation can be checked before ordering.
- Starts without auxiliary aids down to -12℃ Coolant Volume (Engine Only): 20.8 L.
- Genuine and OEM options quoted side by side so the budget decides, not the catalogue
- Built on the NTA855 platform, a Cummins family with parts availability worldwide
Application Scenarios
- Prime mover for a new generator set build
- Standby set engine replacement
- Rental power fleet rebuild
- Containerised power module
Who It Is For
- Genset packagers matching an engine to an alternator
- Rental power companies rebuilding sets between contracts
- Industrial sites replacing the prime mover in an existing canopy
- Telecom and data infrastructure contractors specifying standby power
Problems It Solves
- An engine that does not hold speed under block load makes the whole set unusable.
- Packagers lose weeks when the engine does not match the alternator and the base frame.
- Standby sets sit idle for months and must still start and take load on demand.
- Identifying the right NTA855-G2 variant from a serial number takes experience; MEP Power checks the configuration before quoting.

How It Compares
| Compared with | What to consider |
|---|---|
| A larger engine in the same NTA855 range | Moving up a frame size adds weight, envelope and fuel burn; specify the next size up only if the duty cycle really needs the headroom. |
| A non-Cummins engine of similar output | Parts and service for Cummins families are available in most markets, which matters more over ten years than the purchase price on day one. |
