40kW 50kVA Silent Type Cummins Diesel Generator Set With Stamford Alternator / Leroy Somer Alternator

This 40kW (50kVA) silent diesel generator set is assembled with a genuine Cummins industrial diesel engine and an original Stamford brushless alternator, equipped with a heavy-duty integrated soundproof canopy. It is engineered to deliver stable, clean, and low-noise power for both prime continuous power and standby emergency power applications.

Fully certified with CE, ISO9001 and ISO8528 standards, this genset features reliable performance, low fuel consumption, and minimal maintenance. It is widely used for commercial buildings, medical facilities, schools, telecom base stations, small factories, and construction sites. The optional ATS automatic transfer switch enables fully unattended automatic power switching during mains failure, making it a high-cost-performance premium power solution for global medium-power projects.

• Genuine Cummins Industrial Diesel Engine - Adopts authentic Cummins 4-cylinder inline, water-cooled, turbocharged diesel engine with mature industrial technology. It provides sufficient power reserve, fast load response, low fuel consumption, and low emission performance. Benefiting from the global Cummins after-sales network and universal spare parts supply, the engine supports long-term continuous operation with an ultra-low failure rate.
• Original Stamford Brushless Alternator - Comes with a world-famous Stamford pure copper brushless alternator, featuring Class H insulation, IP23 protection grade and professional 2/3 pitch winding design. Equipped with a built-in AVR automatic voltage regulator, it outputs pure sine wave power with extremely low harmonic distortion, effectively protecting precision instruments, sensitive electronic equipment and industrial loads. The brushless structure eliminates carbon brush wear, greatly reducing daily maintenance work.
• Heavy-Duty Soundproof Silent Canopy - The thickened galvanized steel canopy adopts anti-rust and anti-corrosion coating, filled with high-density flame-retardant sound-absorbing cotton and matched with a large industrial muffler and optimized air duct system. The operating noise is controlled within 68-70dB(A) at 7 meters. The canopy integrates waterproof, dustproof and rainproof functions, adapting to long-term outdoor fixed installation and urban noise-restricted scenarios.
• Intelligent Digital Control System - Configured with industrial-grade Smartgen or DeepSea intelligent controller. It monitors voltage, current, frequency, coolant temperature, oil pressure, rotating speed and running hours in real time. Built-in multiple safety protection functions to realize automatic alarm and shutdown under abnormal working conditions.
• Integrated Base & Vibration Reduction Structure - Heavy-duty integral steel base with built-in fuel tank and high-strength rubber shock absorbers effectively reduces vibration and secondary noise. The integrated structure requires no complex foundation construction, convenient for transportation, hoisting and on-site installation.

• Reliable Electric Start - Standard 24V DC electric starting system ensures fast and stable startup in various harsh environments.
• Full Safety Protection - Automatic alarm and shutdown for faults including low oil pressure, high water temperature, overload, over-voltage, under-voltage and overspeed, protecting the unit from damage.
• ATS Automatic Switching (Optional) - Automatically starts up when mains power fails and shuts down with delay after mains power recovery, realizing unattended emergency power supply.
• Long-Time Continuous Operation - Supports 24-hour stable prime power operation for off-grid areas, remote construction sites and industrial facilities.
• Remote Monitoring & Control (Optional) - Supports remote real-time data viewing, start/stop operation and fault information push via mobile and computer terminals.

• Globally Recognized Classic Configuration - The combination of genuine Cummins engine and original Stamford alternator is a world-class mature power matching scheme, with high global market recognition and zero customer trust barrier.
• High-Quality Stable Power - Stamford brushless alternator delivers ultra-stable voltage and current with low harmonic distortion, safely protecting precision medical, commercial and industrial equipment from voltage fluctuation damage.
• Low Operation & Maintenance Cost - Cummins turbocharged engine features low fuel consumption and long service intervals; brushless alternator avoids carbon brush replacement, greatly reducing long-term maintenance costs.
• Urban Low-Noise Design - Professional silent canopy meets international urban environmental protection standards, suitable for residential areas, hospitals and schools where open-type generators are prohibited.
• Complete Global After-Sales System - Both Cummins and Stamford have global service networks and spare parts supply channels, ensuring fast after-sales support and convenient parts replacement for overseas users.
• Rigorous Factory Quality Control - All units pass 100% full-load aging test and performance inspection before delivery, ensuring stable performance and low failure rate.
• Flexible Customization - Supports customized voltage, frequency, ATS automatic system, remote monitoring and trailer/container configuration to adapt to different national standards and application scenarios.

This 40kW silent Cummins & Stamford generator set is widely used for emergency standby power and daily prime power supply. It is an ideal power solution for shopping malls, office buildings, hotels, residential communities, hospitals, schools, telecom base stations, small and medium-sized factories, construction sites, farms and remote off-grid areas.
