Super Silent 250 kW Natural Gas Emergency Standby Power Generator With ATS Water Cooled

This 250kW (312.5kVA) natural gas generator set features an industrial lean-burn gas engine and full copper brushless alternator. Available in two configurations: super silent canopy and open frame, with standard 50Hz frequency and water cooling design. Supports matched ATS automatic transfer switch. Utilizes natural gas, LNG, or biogas as clean fuel, offering low operating costs, minimal noise, and reduced emissions. Ideal for emergency standby power in commercial buildings, hospitals, residential districts, factories, sewage plants, and noise-restricted urban projects. Complies with ISO 8528 industry standards.

• Industrial Lean-Burn Gas Engine: 4-stroke water-cooled turbocharged intercooled gas engine with closed-loop air-fuel ratio electronic control. Stable combustion for multiple gas fuels with low vibration and minimal exhaust pollution. 24V DC electric start ensures rapid response during power outages. Designed for long service life in standby operation.
• Two Optional Configurations:
  • Open Frame Type: Heavy channel steel integrated base with shock-absorbing rubber pads. Fully exposed layout provides excellent heat dissipation and easy access for maintenance. Ideal for indoor generator rooms to reduce procurement costs.
  • Super Silent Canopy Type: Fully sealed rainproof and dustproof steel enclosure with multi-layer high-density sound-absorbing cotton and large composite silencer. Noise ≤72dB(A) at 7 meters. Independent air intake and exhaust heat dissipation duct allows outdoor placement year-round, meeting urban environmental noise limits.
• Full Copper Brushless Alternator: Class H insulation, IP23 protection grade, with extremely low voltage waveform distortion. Stable three-phase 400/230V output (single phase 220V optional) delivers clean power to protect precision equipment from voltage fluctuations.
• Optional ATS Automatic Transfer Switch: Enables fully unattended emergency power supply. Automatically starts and switches load within 8 seconds during mains power failure, then switches back and shuts down when grid power recovers. Compatible with remote cloud monitoring for operational data and fault alerts via mobile or computer.
• Complete Intelligent Safety Protection System: Special gas generator intelligent controller displays real-time voltage, current, frequency, coolant temperature, lubricating oil pressure, rotating speed, running hours, and gas supply pressure. Multiple protection functions include gas low pressure, gas leakage, overspeed, high water temperature, low oil pressure, overvoltage, undervoltage, overload, and short circuit protection with sound-light alarm and automatic shutdown.
• Integrated Heavy-Duty Base Frame: Welded thick channel steel base with built-in buffer tank and vibration isolation pads. Includes standard gas pipeline interface and drainage outlet. External gas storage tank pipelines and multi-unit parallel cabinets available as upgrades.

• Clean gas fuel significantly reduces daily operation costs with low NOx emissions, meeting strict environmental standards
• Dual structural options adapt to indoor machine rooms and outdoor urban construction or commercial complex scenarios
• Dedicated gas leakage and gas pressure protection provides higher safety than diesel generators
• ATS automatic switching with remote monitoring enables 24-hour unattended operation, reducing labor management costs
• Mature gas power matching technology ensures low failure rate with convenient global spare parts supply and after-sales maintenance
• Comprehensive full-load aging test before delivery guarantees stable and reliable long-term continuous standby operation

Shopping malls, hotels, central hospitals, residential communities, small and medium-sized factories, biogas sewage treatment plants, urban commercial plazas, temporary low-noise engineering projects, and all sites requiring eco-friendly emergency standby power.
