Designed with an open-frame structure without soundproof canopy, this unit features excellent heat dissipation, simple maintenance and high continuous operation stability.

It is widely used for prime continuous power and industrial standby power, ideal for fixed machine rooms, construction sites, factories, mines, industrial parks and remote off-grid areas. Fully compliant with CE, ISO9001 and ISO8528 international standards. Optional ATS automatic transfer switch, remote monitoring system and external fuel tank are available to meet different industrial power supply demands.

Core Features

• Genuine Cummins Industrial Engine (4BTA3.9-G2) - Adopts authentic Cummins 4-cylinder inline, water-cooled, turbocharged and direct-injection diesel engine. With mature industrial-grade technology, strong power reserve, fast load response and low fuel consumption, the engine supports long-time full-load continuous operation. Global after-sales service network and universal spare parts ensure ultra-low failure rate and convenient maintenance worldwide.
• Original Stamford Brushless Alternator - Comes with world-famous Stamford pure copper brushless alternator, H-class insulation, IP23 protection and professional 2/3 pitch winding design. Built-in AVR automatic voltage regulator ensures ultra-stable pure sine wave output with extremely low THD. It protects industrial equipment and precision electrical devices effectively. Brushless structure eliminates carbon brush wear, realizing maintenance-free power generation.
• Open Frame Structure with Excellent Heat Dissipation - Standard open-type base frame design completely exposes the engine and radiator, providing maximum natural air circulation and heat dissipation efficiency. It avoids overheating during long-hour continuous operation, perfectly suitable for fixed indoor machine room and well-ventilated industrial environments.
• Intelligent Full Protection Control System - Equipped with industrial-grade Smartgen or DeepSea digital controller. Real-time monitoring of voltage, current, frequency, oil pressure, water temperature, speed and running hours. Complete fault alarm and automatic shutdown protection functions ensure safe and stable operation of the unit.
• Heavy-Duty Integrated Base & Shock Absorption - Integrated thick steel base with integrated fuel tank and high-strength rubber vibration isolators reduces operating vibration. Compact and rigid structure ensures stable installation, easy lifting, transportation and routine maintenance.

Main Functions

• Stable Electric Start System - Standard 24V DC electric starting system ensures reliable startup in various working temperatures and industrial environments.
• Full Range Safety Protection - Auto alarm and shutdown against low oil pressure, high water temperature, overload, over-voltage, under-voltage and overspeed faults.
• ATS Automatic Emergency Power (Optional) - Realizes automatic start when mains power fails and automatic delayed stop after power recovery for unattended backup power supply.
• 24/7 Continuous Industrial Operation - Excellent heat dissipation performance supports long-term prime power operation for off-grid factories and industrial zones.
• Remote Monitoring & Data Logging (Optional) - Supports remote real-time monitoring, start/stop control and fault record query via network terminal.

Technical Specifications

Competitive Advantages

• Classic Industrial Grade Configuration - Genuine Cummins engine + original Stamford alternator combination is globally recognized for industrial power projects, with ultra-high stability and market credibility.
• Superior Continuous Operation Capability - Open-type design provides unobstructed heat dissipation, effectively solving overheating problems during long-time full-load operation, more suitable for industrial continuous power supply than silent canopy units.
• High-Quality Clean Power Output - Stamford brushless alternator delivers stable voltage and low-distortion current, protecting industrial motors, mechanical equipment and precision instruments.
• Ultra-Low Maintenance Cost - Open structure makes daily inspection, parts replacement and maintenance extremely convenient; brushless alternator requires zero carbon brush maintenance, greatly reducing long-term operating costs.
• Strong Global After-Sales Support - Cummins and Stamford have complete global spare parts and service systems, ensuring fast technical support for overseas industrial clients.
• High Cost-Performance - Without canopy cost, the open-type unit is more affordable for fixed-room industrial projects while retaining full industrial-grade performance.
• Strict Factory Testing - Every unit passes full-load aging test and performance calibration before delivery to ensure stable industrial-grade output.

Application Scenarios

This 45kW open type Cummins & Stamford generator set is widely used for industrial prime power and emergency standby power. It is the best choice for factory machine rooms, industrial parks, construction sites, mines, water treatment plants, farms, remote off-grid areas and large commercial backup power projects.
