Silent Type Cummins Emergency Generator

This 400kW silent emergency backup diesel generator features a genuine Cummins heavy-duty industrial engine, large frame brushless synchronous alternator, and reinforced integrated silent soundproof canopy. Factory pre-installed with ATS automatic transfer switch as standard, it serves as core emergency power for large hospitals, industrial parks, shopping malls, medium-large data centers, high-rise office buildings, and chemical plants.

The integrated unit includes multi-stage composite muffler, dual independent forced cooling system, large built-in daily fuel tank, and intelligent ATS linkage control system. It automatically starts within 3-8 seconds during mains power failure to deliver stable continuous power for critical emergency loads, then automatically switches back to grid power with cooling shutdown after utility recovery. Fully compliant with ISO8528 and CE export standards, it features low noise, IP54 all-weather outdoor protection, and stable long-term unattended standby operation.

• Genuine Cummins Heavy-Duty Industrial Engine: Original Cummins large-displacement engine with electronic high-pressure common rail fuel injection system, abundant power reserve, and strong overload capacity. Reliable performance under long-term standby and frequent startup conditions with low vibration and exhaust noise.
• High-Stability Large Brushless Synchronous Alternator: Large self-excited brushless alternator with high-precision digital AVR regulator, ultra-low harmonic distortion, and pure sine wave power output. Protects precision medical life-support equipment, server clusters, monitoring instruments, and industrial control devices.
• Heavy-Duty Reinforced Low-Noise Silent Canopy: Thickened reinforced steel soundproof shell with marine anti-rust & anti-corrosion paint. Inner walls fully lined with thick flame-retardant high-density sound-absorbing cotton and oversized multi-stage industrial silencer. Running noise ≤74dB(A) at 7 meters.
• Standard Built-In ATS Automatic Transfer Switch: Integrated ATS cabinet enables fully automatic power switching between municipal grid and generator without manual operation. Zero power interruption for core emergency loads with intelligent interlock control.
• Dual Independent Closed Forced Heat Dissipation System: Dust-filter intake shutters matched with double heavy-duty axial exhaust fans form large-flow independent cooling circulation channel. Prevents heat accumulation during long continuous full-load operation.
• IP54 All-Weather Outdoor Integrated Structure: Rainproof, dustproof, and salt-spray resistant canopy requiring no dedicated machine room for outdoor installation. Large-capacity built-in daily fuel tank with reserved external fuel pipe interfaces.
• Comprehensive Multi-Layer Safety Protection Mechanism: Complete protection functions including low oil pressure alarm & auto shutdown, high coolant temperature protection, overspeed, overload, overvoltage, undervoltage, short-circuit, reverse power and earth fault protection.
• Humanized Maintenance Layout & Diversified Optional Accessories: Extra-wide quick-opening maintenance doors for easy filter replacement and engine overhaul. Standard 24V DC heavy-duty maintenance-free electric start system with optional accessories available.
