Stable and commonly used SDEC 300KW high-power diesel generator set

⚙️ I. Advanced structural design
High-strength core components: adopting integral crankshaft, gantry body, flat-cut connecting rod and short piston design, the structure is compact and reasonable, and some models can be interchanged with the old 135 diesel engine, which is convenient for maintenance and upgrading.

Anti-wear optimisation: Equipped with three-stage cyclone type German paper filter air filter, low-temperature ceramic piston ring and high-vacuum exhaust ejection device, it effectively prevents the intrusion of sand and dust, and significantly reduces the early wear under high dust or desert environment.

⛰️ Adaptability to plateau and harsh environment
Excellent plateau performance: matched with J98/J114b exhaust gas turbocharger, the power drop is less than 3% when used at 5000 metres above sea level, which is suitable for plateau, mines and other low-oxygen environments.

Low-temperature cold-start capability: standard intake heater, reserved water heating interface, support -25℃ low-temperature environment fast start.

🌱 Third, environmental protection and low emissions
Clean combustion technology: adopting indented combustion chamber design, improving injection pressure, optimising combustion process, meeting National II (JB8891-1999) or National III emission standards (some models).

Noise control: operating noise ≤ 96-100dB (LP7m), meeting the requirements of GB14097-1999 noise limit.

🛡️ IV. Reliability and maintenance convenience
Optimisation of three leakage prevention and control: the lubrication and cooling system reduces the external piping and adopts brushless alternator to reduce the risk of oil, water and gas leakage.

Convenient maintenance: the body is equipped with a side observation window to facilitate the replacement of connecting rods and axle tiles; the replacement cycle of the filter element reaches 500 hours, reducing downtime.

⛽ V. Outstanding Fuel Economy
Low fuel consumption design: fuel consumption rate ≤ 192-207g/kW-h, oil consumption rate ≤ 0.3g/kW-h, significantly reducing long-term operating costs.

Long maintenance intervals: centrifugal rotor oil filter and high-efficiency fuel filter extend maintenance intervals and support 500 hours of continuous operation.

❄️ VI. Cold Start and Wide Temperature Range Operation
Cold Start Guarantee: Standard air intake preheating system, combined with coolant heating options, adapts to the operation in cold areas.

Heat dissipation optimisation: water pump flow enhancement and piping design improvement ensure stable operation in -40℃ to 50℃ environment.

🏭 VII. Wide range of application scenarios
Applicable to fire emergency, data centres, mines, oilfields, communication base stations, municipal engineering and other high-demand fields, especially suitable for plateaus, cold areas, dusty environments.

🔧 VIII. Flexible configuration
Generator compatibility: can be adapted to Marathon, Stamford, Leroy Somer and other brands of generators and AVR regulator system.

Intelligent expansion: support for ATS automatic switching cabinet, silent box, remote monitoring (‘three remote’ function) and other custom solutions.

🛠️ IX. After-sales and service system
Covering 90% of county-level areas in China, more than 300 service stations provide joint warranty service, and the CRM system supports rapid response to failures.

Emission standard National Ⅱ/National Ⅲ Depends on the specific model.
Through modularised design and upgraded materials and technology, the unit maintains high stability under extreme working conditions, which is suitable for scenarios with stringent requirements on reliability. Specific selection needs to take into account the altitude, temperature and compliance requirements (e.g. National III emission), and further comparison can be made between engines such as SC12E (plateau type) and SC15G (long-stroke economic type).
