Prime 400kVA, standby 440kVA silent genset driven by Cummins 6ZTAA13-G2 engine, 50Hz 3-phase 400V, PF0.8, ISO8528 compliant. Inline 6-cylinder turbo aftercooled with electronic fuel system, matched with IP23 H-class brushless alternator. Soundproof canopy with cooling & damping structure, rainproof and low noise for continuous & emergency power of factories, buildings and hospitals.
Internet data centres and colocation facilities operate on a simple rule — no power means no revenue. Server racks drawing continuous load, UPS arrays managing battery state of charge, and precision in-row cooling cannot tolerate a transfer gap exceeding the UPS hold-time budget. The JIUAN Power 440KVA Cummins diesel generator — Model CDC440KVA, driven by the Cummins 6ZTAA13-G2 13L engine from DCEC's ISO 9001-certified Wuhan manufacturing base — provides 320KW/400KVA prime and 352KW/440KVA standby, purpose-engineered for data centre standby duty. Every 400KVA silent Cummins genset leaves the factory ISO 8528-verified, with pre-shipment test documentation as standard.
The Cummins 6ZTAA13-G2 engine at the core of this soundproof diesel generator is manufactured at DCEC Dongfeng Cummins' ISO 9001-certified Wuhan facility — an inline six-cylinder, 13L platform with a 130mm bore, 163mm stroke, and 17:1 compression ratio. A Holset turbocharger with air-to-air intercooler and high-pressure mechanical fuel injection with electronic GAC governor hold frequency deviation to ≤3% from cold-start through 110% transient, ensuring UPS input circuits and PDU metering systems receive stable power through every load-step pickup. Rated BSFC of 192–194 g/kW·h and a 15,000-hour overhaul interval minimise per-rack fuel cost and scheduled downtime over the data centre's depreciation horizon.
The weatherproof shell of this 440KVA Cummins diesel generator is fabricated from ≥2.0mm cold-rolled steel panels, finished with a 120°C high-temperature electrostatic enamel coat, and lined with 40 kg/m³ flame-retardant rock wool — measured acoustic output at 7 metres is 65–68 dB(A), within campus noise ordinances at suburban data centre sites. A 950-litre integral skid-frame fuel tank provides over 8 hours of full-load autonomous runtime during planned grid maintenance windows or utility outages. Each 400KVA silent Cummins genset is shipped pre-fitted with a DeepSea DSE7320 controller; integrated ATS logic completes mains-to-generator transfer within 3–6 seconds — within standard UPS hold-time windows — and returns the load automatically on utility restoration.
JIUAN Power ships every CDC440KVA 440KVA Cummins diesel generator with factory-documented step-load acceptance results — six incremental duty bands from 0% through 110% — and a PDF performance certificate for Tier III audit documentation. Documentation includes 3D engineering assembly drawings, magnified anti-counterfeiting component photographs, and a PICC insurance-backed 5-year warranty policy recording the Cummins 6ZTAA13-G2 engine serial number for data centre DCIM asset registers. A 150-page generator operations manual in five language editions (English, Arabic, French, Spanish, Portuguese), electrical schematics, a 3D disassembly animation CD, and service wrenches with testing meters complete the delivery. Generator enclosure panel gauge is checked by precision digital calliper before despatch; warranty spares reach any major port within 3–5 working days, valid for the full 5-year warranty period.

The Cummins 6ZTAA13-G2 engine in this 440KVA Cummins diesel generator pairs Holset turbocharging with high-pressure injection and an electronic GAC governor, completing load acceptance within 3–6 seconds of ATS transfer — inside the hold-time of standard UPS systems. JIUAN Power films and provides a step-load acceptance test video for each unit, confirming ISO 8528 output across all six incremental duty bands before despatch. Rated BSFC of 192–194 g/kW·h and a 15,000-hour overhaul interval deliver the lowest annual fuel and maintenance cost in the 400KW standby class.
Each CDC440KVA carries a PICC-covered 5-year warranty certificate with the Cummins engine serial number entered on the document — a traceable record for data centre DCIM platforms, insurance renewal schedules, and investor asset registers. JIUAN Power checks enclosure steel gauge by precision digital calliper and supplies 3D engineering drawings alongside magnified anti-counterfeiting component photographs, letting remote DC procurement teams audit this soundproof diesel generator's construction standard from their desk. Warranty components are air-freighted to any major port within 3–5 working days through JIUAN Power's global Cummins network.
The Stamford or Leroy-Somer Class H brushless synchronous alternator in this 400KVA silent Cummins genset — IP23-rated, vacuum-impregnated all-copper windings — holds voltage regulation within ±1% and total harmonic distortion below 3%, satisfying the input specification of enterprise UPS bypass circuits, rack PDU metering cards, and in-row cooling controllers. C5-M anti-corrosion coating (ISO 12944) is specified for tropical coastal and island edge-DC deployments; cold-region kits — jacket water heaters, fuel preheaters, and arctic lubricant packages — ensure dependable starts to -30°C for high-latitude data centre sites, keeping the 440KVA Cummins diesel generator ready regardless of ambient conditions.
The CDC440KVA 440KVA Cummins diesel generator serves internet data centres, colocation facilities, CBD office towers, national broadcast infrastructure, petrochemical plant control rooms, port container terminals, and water treatment pumping stations across the Middle East, Southeast Asia, Sub-Saharan Africa, and Latin America. JIUAN Power fully pre-assembles every soundproof diesel generator before despatch — connection requires only fuel and power-cable termination.
FAQ
Q: How does this 440KVA Cummins diesel generator fit a Tier III data centre's N+1 backup power plan?
A: At 320KW prime, the CDC440KVA fills the single-genset slot in a Tier III N+1 configuration protecting a 0.8-power-factor rack load of up to 256KW. The DSE7320 ATS transfers within 3–6 seconds — inside the typical 10-second UPS hold-time window — and the 950-litre tank sustains over 8 hours of full-load runtime, covering planned utility maintenance windows without refuelling.
Q: What is the fuel consumption of this 400KVA silent Cummins genset at full load?
A: The Cummins 6ZTAA13-G2 engine achieves 192–194 g/kW·h BSFC at rated output — roughly 62–67 litres per hour at 320KW prime load. Over the 15,000-hour overhaul interval, this places the CDC440KVA among the most fuel-efficient options in the 400KW standby class.
