Diesel Generator Sets with Cummins Engines, TC Series

ESP (Emergency Standby Power) is the maximum power available during a variable load for the duration of an emergency, typically with no more than 200 hours per year of operation. PRP (Prime Rated Power) is the power available for an unlimited number of hours per year in a variable load application, generally around 10% less than ESP. For continuous or primary power needs, PRP is the relevant rating to consider.

The TMC series uses a range of Mitsubishi industrial diesel engines. Smaller models (TMC750–TMC825) use the S6R2 series (29.96 L displacement), mid-range models (TMC1375–TMC1650) use the S12R series (49.03 L), and larger models (TMC1900–TMC2250) use the S16R series (65.37 L). The largest model, TMC2500, is powered by the S16R2-PTAW-C with a 79.9 L displacement.

Canopy versions are available for models TMC750 through TMC1900. Larger models including TMC2000, TMC2250, and TMC2500 are currently listed as open-type configurations only. Please contact us directly for customized enclosure solutions for higher-capacity units if required.

To select the correct generator capacity, calculate your total connected load in KW or KVA, then add a safety margin of 20–25% to handle startup surges and future load growth. If the generator will serve as a standby emergency unit, use the ESP rating as your reference. For continuous or prime power applications, refer to the PRP rating. Our technical team can assist with a detailed load analysis.

Each model in the specification table above includes a "Details" download button that links directly to the corresponding PDF datasheet. The datasheets contain full technical specifications, electrical parameters, dimensional drawings, and installation guidelines for each generator model.

Fuel consumption varies significantly across the TMC range. At full ESP load, consumption ranges from approximately 123 L/h for the TMC750 up to 464 L/h for the TMC2500. These figures are measured under full-load conditions. Actual consumption in real-world operation will vary depending on load factor, ambient temperature, altitude, and fuel quality. Refer to each model's datasheet for partial-load consumption curves.
