A wide range of optional features is also available to tailor the unit to your specific site and application requirements.

Engine Performance and Fuel Efficiency

The Cummins QST30 G5 engine is the backbone of this generator, producing a gross standby output of 1,112 kWm (1,491 bhp) and a net standby output of 1,076 kWm after accounting for fan losses. Running at 1,800 RPM, the engine achieves a BMEP of 2,432 kPa at standby rating, reflecting the high cylinder pressures that enable this level of output from a 30.48-liter displacement. 

The bore and stroke measure 140mm x 165mm across all 12 cylinders. Exhaust gas temperature reaches 525 degrees Celsius at standby with a gas flow rate of 3.67 cubic meters per second, making proper exhaust system planning essential. At prime power rating, fuel consumption drops to 248 L/h at full load and 126 L/h at 50% load, giving operators meaningful fuel savings during partial-load operation.

Cooling System and Thermal Management for the BCC 1000S-60 T2

The BCC 1000S-60 T2 features a water-cooled engine with a radiator designed for demanding thermal environments, supported by a fully guarded engine-driven fan. The radiator cooling air flow reaches 19.0 cubic meters per second, with a maximum allowable air-on temperature of 51 degrees Celsius and a maximum coolant temperature of 104 degrees Celsius. 

Total oil capacity including filters is 154 liters, with typical oil pressure at rated speed running at 345 kPa. Heat rejection to the engine cooling water at standby rating is 380 kW, with an additional 140 kW radiated from the engine itself. Heavy duty rubber anti-vibration mountings are standard, minimizing vibration transfer to the mounting surface and protecting both the generator and surrounding structure.

Alternator Specifications

The CGT Stamford HCI 634 alternator is a self-excited, single-bearing unit directly coupled to the engine using a 3-phase, 4-pole, Winding 311 configuration. At standby rating, the alternator operates at 27 degrees Celsius, while prime power operation is rated at 40 degrees Celsius. 

Class H insulation provides excellent thermal resilience, and the MX 321 automatic voltage regulator maintains voltage within plus or minus 0.5% under varying load conditions. The 24V electrical system uses two series-connected 624 CCA batteries with a combined cold cranking capacity of 1,010 amps, ensuring reliable starting even in challenging conditions.

Control System Options for the BCC 1000S-60 T2

The standard BC 7210 Digital Auto Start controller, based on Deep Sea Electronics technology, provides manual and automatic remote start capability with an LCD display covering coolant temperature, oil pressure, volts, amps, frequency, engine hours, and battery voltage. An automatic cool-down timer, emergency stop button, and auxiliary inputs and outputs round out the standard feature set. 

Operators requiring greater monitoring capability can opt for the BC 7310 or BC 7320, which add pre-alarms, digital kW and power factor display, over/under voltage and over-current protection, and full RS485 telemetry with SAE J1939 CANBus communication. For facilities requiring synchronization, the BC 7510 supports set-to-set synchronization while the BC 7520 enables single set-to-mains synchronization, making the BCC 1000S-60 T2 a strong candidate for parallel power plant configurations.
