The extended maintenance cycle effectively reduces long-term fuel cost and daily maintenance investment for users.
- Strong Environmental Adaptability: Designed with H-class high-temperature resistant insulation and IP23 protection grade. The whole machine undergoes professional anti-rust and anti-corrosion spraying treatment, capable of stable operation in high temperature, high humidity, dusty and rainy outdoor complex environments.
- Complete Intelligent Safety Protection System: Integrated comprehensive protection functions including low oil pressure alarm, high coolant temperature shutdown, overspeed protection, overvoltage, undervoltage, overload and short-circuit automatic protection. The unit will automatically alarm and shut down in case of faults to protect engine and alternator from damage.
- Humanized Maintenance Layout: Large maintenance access doors are reserved on the silent canopy, with centralized control panel and external wiring terminals. The reasonable layout facilitates daily inspection, oil and filter replacement, fault troubleshooting and regular overhaul, saving maintenance time and labor cost.
- Continuous Prime Power Supply: Provides 120KW rated prime power and 132KW standby power, supporting 24-hour uninterrupted partial and full-load operation for medium-sized factories, construction sites and remote industrial areas.
- Low-Noise Environmental Protection Operation: Professional fully enclosed silent structure allows compliant installation in noise-restricted urban areas, residential zones and commercial buildings, satisfying environmental assessment requirements.
- Intelligent Monitoring & Automatic Control: Digital intelligent controller real-time displays voltage, current, frequency, coolant temperature, oil pressure, running hours and fault records. It supports manual start-stop, with optional ATS automatic transfer switch to realize unattended emergency power switching.
- Strong Transient Impact Load Resistance: Excellent dynamic response performance, capable of withstanding instantaneous startup impact of medium-sized motors, water pumps and mechanical equipment, adapting to complex variable industrial loads.
- Fast Emergency Backup Power Support: Features fast startup and rapid voltage stabilization. It can immediately take over power supply once mains power fails, avoiding production interruption and economic losses caused by sudden blackouts.
- All-Weather Indoor & Outdoor Operation: Optimized circulating heat dissipation system and sealed silent canopy ensure stable and reliable all-weather operation under open-air and semi-outdoor working conditions.
