Open Frame Diesel Generator

 

 

 

Application scenarios:

• Construction site and infrastructure: Provide instantaneous power supply for tower cranes and concrete mixing stations.
• Mine mining: Suitable for mining operations that are far from the main power grid, to drive heavy equipment such as crushers.
• Oil and gas fields: Provide self-generated power (for self-use) for drilling platforms and field workstations.
• Data center and factory: As a backup power source (Standby Power), it constitutes the final line of defense in the power supply system.
• Agriculture and Irrigation: Providing power for large irrigation systems on remote farms.

 

Technical Specifications:

• Power range: 30 kVA - 4000 kVA (Supports dual frequency switching between 50Hz and 60Hz).
• Engine brand: Optional models include Cummins, Perkins, Daiozhi, Yuchai, Weichai, etc. (Customers can specify as well).
• Generator brand: Standard configuration includes international brands such as Stanford and Lillenschmidt, ensuring a voltage stability rate of ≤ ±1%.
• Control system: Standard features include automatic start/stop functionality and remote monitoring interface (supporting API data connection).
• Fuel system: Standardly equipped with a floor-mounted fuel tank, which can sustain operation for over 8 hours. An optional external large-capacity fuel tank is also available.

1. Continuous operation in high-temperature environments leads to overheating, reduced capacity, or even shutdown of the equipment.
When the ambient temperature remains above 45℃, the probability of overheating and shutdown of ordinary equipment increases by approximately 40% after running at full load for more than 4 hours. Each shutdown causes production to be interrupted for 2 to 4 hours, and in severe cases, the maintenance cost can exceed the purchase cost by 20%. Our solution adopts an open structure to enhance natural ventilation, and is equipped with a standard large-capacity water tank and mechanical fans for 55℃ operating conditions. The on-site installation must ensure a ≥1.5-meter heat dissipation channel around. For multi-machine parallel operation, independent inlet and outlet air ducts are used. After implementation, the equipment can still output the rated power at 55℃, and the probability of overheating shutdown is reduced by more than 90%.

2. In remote areas, sudden equipment failures result in slow repair response and long downtime.
In remote operating conditions, the average time for fault location and replacement of conventional equipment is 6 to 8 hours. When disassembly and assembly are inconvenient, it even increases by more than 50%. The total loss from a single incident easily exceeds 30,000 yuan. We adopt a single-side centralized maintenance design, with all filters and oil pumps located on the same side without the need to detour. Key components are equipped with quick disassembly structures, and the overall installation and replacement can be completed within 1 hour. On-site, a mobile crane can be selected, and the multi-machine system supports N+1 redundancy configuration. After implementation, the maintenance time is reduced to 2 hours, the replacement of key components is compressed to 1 hour, and the overall maintenance downtime is reduced by 50% to 70%.

 

 

1.Ultra-high cost-effectiveness and flexibility

• Low-cost investment: By removing the noise reduction cover and related accessories, the procurement cost has been significantly reduced compared to the quiet model.
• Globalized logistics: Compact structure, facilitating container transportation, and reducing maritime shipping costs.

2. Fully enclosed maintenance experience

• Barrier-free maintenance: All consumables and components (oil filter, fuel pump, fuel injection port) are designed on the same side of the machine body. Maintenance personnel can operate without having to walk around.
• Quick replacement: In case of major repairs, the generator or engine end can be quickly disassembled, reducing the downtime.

3. Exceptional adaptability to harsh environments

• Efficient heat dissipation: The open structure of the unit gives it inherent advantages of natural air cooling or water cooling when operating under high load, effectively preventing the cylinder from overheating. It is suitable for continuous operation in mining areas or deserts with an ambient temperature as high as 55℃.
• Customized coating: Utilizes anti-corrosion surface treatment to withstand the high salt spray environment in coastal areas and the high dust environment in industrial settings.

 

1. Factory direct supply, ensuring both price and delivery time

• No middleman price difference: From R&D, production to testing, the entire process is independently controlled, resulting in lower costs under the same configuration.
• Delivery time is controllable: With standardized production lines and sufficient inventory of core components, regular orders are delivered within 15-25 days, and urgent orders can be processed on an expedited basis.

 

2. Truly on-demand customization capability

We do not sell "generic machines", but provide customized solutions based on your actual working conditions:

• Power coverage: 30kVA ~ 4000kVA, freely switchable between 50Hz and 60Hz
• Brand options available: Engine options include Cummins, Perkins, Yuchai, Weichai, etc.; Generator options include Stanford, Lielisenma, etc.
• Environmental Adaptation: Specialized kits for high-altitude environments (≥3000m), extremely cold conditions (-40℃), high dust levels, and high salt spray conditions.
• Electrical configuration: Supports ATS automatic switching cabinet, multi-machine parallel operation, remote monitoring, etc.

 

3. Reliable quality

• Compliant with ISO9001 standards.
• Each unit is tested at 100% load before leaving the factory, and a test report is issued.
