Benefiting from the robust 37.8L large-displacement design of the KTA38 series engine, this premium 1250KVA Cummins standby genset features superior transient load capacity, an ultra-long overhaul cycle, and globally available spare parts. Consequently, this dependable industrial diesel genset ranks as the top tender-choice backup power unit across domestic and overseas industrial markets, ensuring maximum reliability as a critical standby power generator.

Genuine CCEC KTA38-G4 Engine with Abundant Power Reserve

The power core is authentic CCEC KTA38-G4 diesel engine with 60° V-type 12-cylinder four-stroke layout, total displacement 37.8L, bore & stroke 159mm×159mm, fitted with Holset turbocharger plus air-to-air intercooler and original Cummins PT-EFC electronic fuel injection system, rated speed 1500RPM for standard 50Hz grid. Sufficient power margin guarantees full 1250KVA standby output without voltage/frequency drop under sudden full load spike. Wet replaceable cylinder liner and optimized combustion chamber realize outstanding high-temperature & abrasion resistance; with customized high-altitude kit, the engine keeps rated power output at 3500m elevation or 50℃ ambient temperature. Global Cummins aftersales network ensures universal spare parts supply, overhaul lifespan exceeds 20000 working hours to cut long-term downtime loss.

Dual Rated Power for Prime & Standby Dual Working Mode

Prime Rating 1125KVA(900KW): Complies with PRP continuous power specification, runs steadily under 80% normal load for daily auxiliary factory power supply; Standby Rating 1250KVA(1000KW): ESP emergency standby rating only for blackout backup, permits short-term 10% overload to counter large motor starting inrush current, avoiding production halt, medical device shutdown and server crash from unexpected power cut. Standard 400/230V three-phase four-wire output at PF0.8 lagging, customized 60Hz/440V version available to meet grid requirement of Middle East, Africa and Southeast Asia countries.

Low Fuel Consumption to Reduce Full-Cycle Operation Expense

Optimized air intake and fuel injection design of KTA38-G4 cuts full-load specific fuel consumption down to 208g/kW·h, 7% more fuel-efficient than peer domestic gensets. Integrated large-capacity base fuel tank supports over 6.5 continuous working hours under full load, minimizing labor cost from frequent refueling. Equipped with genuine Fleetguard triple filter (air/fuel/lube oil) to block impurities effectively and extend filter replacement cycle, lowering regular spare part expenditure for long-term standby application.

Premium All-Copper Brushless Alternator Delivers Clean Safe Power

Industrial single-bearing brushless self-excited synchronous alternator adopts full-copper winding with vacuum impregnation treatment, Class H insulation & IP23 protection grade, outstanding anti-moisture & anti-salt-spray performance for coastal petrochemical plants and open-pit mines. Voltage steady regulation ≤±1%, THD＜3% ensures smooth clean power to protect sensitive equipment including server, medical MRI and industrial PLC. Standard molded case circuit breaker integrates five safety protections: overload, short-circuit, under-voltage, overspeed and high coolant temp to prevent unexpected unit burnout.

Intelligent Auto Control for 24H Unattended Automatic Switchover

Factory-mounted Deepsea DSE7320 LCD controller (ComAp/Smartgen optional) with bilingual English-Chinese display, real-time monitoring of voltage, current, frequency, coolant/oil temperature, lube pressure, total runtime and fault codes. Built-in ATS linkage program enables auto start on mains loss, delayed auto shutdown after power recovery and fault alarm stop. Optional remote cloud monitoring module allows remote start-stop & data checking via mobile phone or PC, perfect for unmanned power station and data center backup matching.

Multiple Customized Structure for Full-Range Environment Compatibility

Heavy-duty thick steel welded skid with integrated compound vibration dampers to eliminate strong runtime vibration; four optional configurations: open frame, silent canopy, standard containerized type and trailer mobile unit. Silent version noise ≤76dB(A)@7m to satisfy urban hospital & commercial area noise limit; operational ambient covers -25℃~+50℃, cold-region optional water jacket heater and heavy-duty dust-proof air filter for high-dust mining sites, no extra structural modification required for global installation.
