As the core basic model of industrial-grade power generation equipment, EPOWER open-frame generator set has a high cost-effectiveness, flexible adaptability and reliable performance, and builds a full-power coverage solution from basic power consumption to complex loads, which deeply meets the power guarantee needs of diversified scenarios.
Adopting a four-in-one integrated structure of engine, alternator, control panel and common base, the whole machine follows the modular design concept:
Space efficiency: The open layout without casing is smaller than the closed unit with the same power 40% smaller, 30% lighter, removable heavy-duty mobile wheels as standard at the bottom (optional 3-ton forklift slot), one person can move within 10 meters, and deployment efficiency in restricted scenarios such as narrow construction sites and rooftop platforms is increased by 60%.
Heat dissipation performance: The engine compartment reserves a 300mm heat dissipation spacing, and is equipped with an intelligent temperature-controlled silicone oil fan. When running at full load in a high temperature environment of 50℃, the oil temperature is controlled within 110℃, avoiding the risk of "boiling", and supporting 24-hour continuous operation.
Electrical protection: The control panel and generator adopt IP23 protection level, and the wiring terminals are equipped with waterproof rubber sleeves as standard. When dealing with light rain and dusty environments, the insulation resistance decrease rate is delayed by 35% compared with similar products, which meets the needs of outdoor open-air operations.
Integrate 12 major brand engine resources (Cummins, Perkins, Scania, Mitsubishi, Weichai, etc.), covering 20-2000kW Power range, supports diesel, natural gas, gasoline and other fuel types:

Medium power segment (50-500kW): For construction sites and small factories, turbocharged models are used, with transient load response time of<5 seconds, supporting the start-up of impact equipment such as welding machines (60% temporary load rate) and concrete mixers, and the control panel integrates overload / Under-frequency dual protection, fault response time <0.2 seconds.
High power segment (500kW+): Applied to data centers and hospitals, equipped with multi-machine parallel synchronization modules (supporting 8 parallel machines), the voltage phase difference is controlled within ±1.5°, and with intelligent load balancing system to achieve N+1 Redundant backup, power failure switching time<200ms, ensuring continuous operation of precision loads such as MRI equipment and servers.
Industrial Production: Provide ±0.5Hz frequency stability for automated production lines and adapt to PLC control equipment; standard anti-static grounding terminals reduce the impact of electromagnetic interference on sensors and avoid product defects caused by voltage fluctuations.
Commercial scenario: The shopping mall/hotel application model can be equipped with an optional noise reduction apron (noise ≤85dB at 1 meter after installation) to meet the environmental requirements during business hours; built-in ATS automatic switching device, which starts within 10 seconds after the mains power is interrupted to maintain the continuous operation of elevators and cold chain equipment.
Medical field: Passed ISO 13485 medical-grade certification, the engine vibration value is controlled at ≤2.5mm/s to avoid resonance interference to precision medical equipment (such as CT machines); equipped with a dual-battery redundant starting system, the low-temperature starting success rate is increased to 99.7%.
Remote areas: Plateau-type units are equipped with altitude compensation devices (applicable below 4,000 meters), and the power attenuation rate is ≤8%; coastal models use cathodic protection anti-corrosion treatment, and the insulation life of the generator winding is extended by 25% to cope with salt spray erosion.
Convenience of maintenance: The open structure increases the access efficiency of wearing parts such as filters and belts by 50%, and the daily maintenance time is shortened to 20 minutes; the standard maintenance cycle reminder light (based on the number of operating hours) avoids the risk of failure caused by missed maintenance.
Fuel economy: The high-pressure common rail engine saves 12% of fuel compared to traditional models. When the 500kW unit is running at full load, the fuel consumption per hour is ≤110L. It is equipped with a 150L built-in fuel tank (optional 300L expansion), meeting 8 Hours of continuous power supply demand.
Cost-effectiveness: 30% lower cost than closed units of the same power, 3 years/5000 hours warranty for core components (engine, generator), annual average failure rate controlled below 1.2%, and full life cycle operation and maintenance costs reduced by 22%.
EPOWER open-frame generator set is "basic but not basic" ’s design concept, while maintaining high cost performance, through precise power classification, strict environmental adaptation and humanized operation and maintenance design, it has become the cornerstone of reliability for industrial standby, temporary power supply and emergency guarantee scenarios, and uses professional technology to ensure the stable output of every kilowatt-hour of electricity.
Advantages and disadvantages of open diesel generator sets
Advantages
.Good heat dissipation performance: The open structure allows the heat inside the unit to be quickly dissipated to the surrounding environment. Diesel engines generate a lot of heat during operation. The open design avoids heat accumulation, helps maintain the engine and generator within a suitable operating temperature range, ensures efficient and stable operation of the equipment, and extends the service life of the equipment.
.Easy to maintain and repair: Since there is no obstruction of the closed shell, technicians can easily access the various components of the unit. Whether it is daily oil inspection and filter replacement of the engine, or maintenance of the brushes, windings and other parts of the generator, the operation is more convenient. This greatly shortens the maintenance time, reduces maintenance costs, and improves the maintainability of the equipment.
.Relatively low cost: Compared with closed diesel generator sets, open units do not need to be equipped with complex and expensive sound insulation, dustproof shells and related shock absorption devices. This gives it a clear advantage in equipment procurement costs. For users with limited budgets but power generation needs, such as small factories, temporary construction sites, etc., open diesel generator sets are an economical choice.
Disadvantages
.Severe noise pollution: When the open diesel generator set is running, the combustion process of the engine, the operation of mechanical parts and exhaust will generate large noise. These noises will cause serious interference to the surrounding environment and are not suitable for places with strict noise requirements, such as schools, hospitals, residential areas, etc. If it is used in these places, additional sound insulation and noise reduction measures are required, which increases the cost and complexity of use.
.Susceptible to environmental influences: The unit is directly exposed to the external environment and is easily eroded by dust, rain, wind and sand. Dust may enter the engine, accelerate the wear of mechanical parts and affect engine performance; rain may cause electrical components to short-circuit and damage equipment; wind and sand may also block the air filter, reduce the intake efficiency, and thus affect the power generation efficiency and stability of the unit.
.Inadequate protection performance: The open design makes the components of the unit lack effective physical protection. In places with dense personnel or potential safety risks, safety accidents may be caused by accidental touch by personnel. In addition, the equipment is more susceptible to external damage, such as animal climbing, malicious collision, etc., which affects the normal operation of the unit.
