Product Advantages
(1) High Efficiency & Energy Saving: Low Gas Consumption + High Conversion Efficiency
The generator set features the golden combination of the Steyr T12 engine and EN custom generator, paired with a stoichiometric combustion closed-loop control system. The air-fuel ratio control accuracy can reach ±2%, resulting in a 5%-8% reduction in gas consumption compared to industry-standard products. The generator achieves a high conversion efficiency of 93.5%, further reducing energy transmission losses. For example, in a parallel operation with 5 units, approximately 120,000 Nm³ of natural gas can be saved annually (calculated based on 3000 operating hours per year), significantly lowering energy costs for users.
(2)Stable & Reliable: Industrial-Grade Configuration + Rigorous Testing
Core Imported Components: The engine control system is from ECI (USA), the throttle valve is from Bosch (Germany), spark plugs are from NGK (Japan), and the generator’s main controller can be selected from world-renowned brands like Comap (Czech Republic), DEIF (Denmark), and DSE (UK). This reduces the failure rate of critical components by over 60%.
Full-Process Testing: Each unit undergoes a comprehensive 72-hour full-load continuous operation test, high and low-temperature environmental simulation testing (-20℃ to 50℃), and 12 other rigorous tests, ensuring stable performance immediately after delivery.
Extended Maintenance Cycle: The engine overhaul cycle extends to 36,000 to 60,000 hours, 1.5 times longer than the industry average, reducing downtime for maintenance and improving equipment utilization.
(3) Flexible Adaptability: Multi-Scenario + Customizable Services
Multiple Operation Modes: Supports grid connection, parallel operation, off-grid, automatic control, and other operating modes. In a 5-unit parallel configuration, intelligent load distribution is achieved, automatically adjusting the number of operating units when load fluctuations occur, preventing energy waste from "overpowering" (i.e., underloaded units).
Strong Environmental Adaptability: Equipped with an independent cooling system and temperature control system, the generator can still deliver full power output in high-temperature environments up to 50℃. In temperatures as low as -20℃, the pre-heating system allows for rapid startup.
Customizable Solutions: The generator set can be tailored to meet specific needs, such as adjusting parameters, appearance, structure, and control systems based on user gas quality (e.g., low calorific value natural gas, coal seam gas), voltage levels, room space, and control requirements. For instance, intake systems can be optimized for users in high-altitude areas to ensure no power loss.
Why Choose Multi-Unit Parallel Operation?
(1) Core Value of Parallel Operation
Enhanced Power Supply Reliability: When 5 units operate in parallel, if one unit fails, the remaining 4 units can automatically share the load, preventing an overall power supply interruption. This is particularly crucial for environments with high power continuity demands, such as data centers, hospitals, and semiconductor factories.
Optimized Energy Efficiency: The number of operating units can be adjusted based on power load fluctuations (e.g., only 1 unit starts when load is <1250kW, 2 units start when load is 1250kW-2500kW). Compared to running a single large generator at full load, this approach improves energy utilization by 15%-20%.
Reduced Initial Investment: The number of units can be increased gradually as the power load grows, avoiding a large upfront investment and easing financial pressure on the company.
Ease of Maintenance: Units can be alternated for maintenance without requiring a full shutdown, ensuring continuous production operations.
(2) EN Parallel Technology Advantages
EN has developed a parallel control system specifically for the 1250kW Steyr T12 generator set, utilizing digital synchronization technology. Key features include:
Grid Connection Time: Less than 3 seconds for seamless synchronization.
Load Distribution Accuracy: Within ±2%, ensuring precise load balancing across all units.
Stability for 5+ Units: Enables stable parallel operation for 5 or more units.
Black Start Capability: In the event of a power grid failure, the system can automatically start the units and restore power within 10 seconds, meeting emergency power needs.

Application Scenarios
(1) Industrial Park Self-Supplied Power Stations
For high-energy consumption industrial parks such as chemical, metallurgical, and automobile manufacturing, stable power supply is provided using local natural gas resources to replace traditional coal-fired power generation, reducing carbon emissions in alignment with the national "dual carbon" policy. The 5-unit parallel configuration meets peak electricity demands of the park, while during off-peak periods, certain units can be shut down to reduce operational costs.
(2) Associated Gas Utilization in Natural Gas Fields
At natural gas extraction sites, associated gas (with methane content >85%) generated during the extraction process is directly used for power generation. This prevents energy waste and environmental pollution from flaring the associated gas. The generated power can supply the extraction equipment, and surplus electricity can be sold to the grid, improving resource utilization and economic benefits.
(3) Emergency Power Supply for Large Commercial Complexes
Provides emergency power supply for shopping centers, hotels, office buildings, and other commercial venues. The 5-unit parallel configuration can meet the full load requirements for air conditioning, elevators, lighting, etc., ensuring uninterrupted operation during grid power outages. With low noise levels and compact size, the units are well-suited for commercial environments.
(4) Backup Power Supply for Data Centers
Data centers require extremely high power reliability (downtime < 1 minute/year). The 1250kW Steyr T12 generator set (5 units in parallel) can serve as a backup power supply. Paired with an automatic switching system, the generators can start within seconds following a power outage, ensuring continuous operation of critical equipment such as servers and cooling systems.
