DIESEL GENERATOR DE-550BDS

Diesel Generator DE-550BDS: 400 kW of Industrial Power

Ensuring energy independence for large manufacturing plants, shopping malls, residential complexes, and critical infrastructure facilities requires equipment of a special class. The DE-550BDS diesel generator with a nominal power of 400 kW (500 kVA) and a maximum power of 440 kW (550 kVA) is a flagship solution from Darex Energy, built on advanced French technologies.

This station is capable of withstanding 24/7 loads, providing stable voltage to hundreds of consumers simultaneously. Thanks to the use of the Baudouin engine, the generator combines high performance with fuel efficiency unattainable for many competitors in the 500+ kVA class.

Baudouin 6M21G550/5 Engine: High-Volume Efficiency

At the heart of the unit lies the 6-cylinder inline diesel engine Baudouin 6M21G550/5 with a displacement of 12.54 liters. This is a low-speed (1500 rpm) industrial power unit designed for heavy operating conditions.

Why engineers choose this engine:

• Impressive Response: Thanks to turbocharging with an intercooler and electronic injection control, the engine instantly reacts to load changes, keeping the frequency within strict limits.

• Fuel Economy: The high-pressure Common Rail system ensures perfect fuel atomization. Diesel consumption at 75% load is only 75.3 L/h, and at 50% load — about 51 L/h. With a tank volume of 850 liters, this guarantees more than 11 hours of autonomous operation without refueling.

• Reliable Start: The engine is equipped with a coolant heating system, which ensures a confident start in automatic mode even at temperatures down to -30°C.

Alternator and Output Parameters

The generator is equipped with a brushless synchronous alternator with 100% copper winding. High insulation class (H) and IP23 protection allow the unit to work in conditions of high humidity and dust.

The Automatic Voltage Regulation (AVR) system with high response speed stabilizes the output voltage of 400V with an accuracy of ±0.5-1%. This allows you to safely connect sensitive equipment to the generator: CNC machines, server racks, medical equipment (MRI, CT), and building life support systems.

Control and Integration: Datakom

The “brain” of the power station is the Datakom controller (or DSE), which turns a pile of metal into an intelligent system. The control panel features an intuitive interface.

Automation capabilities:

• Full Automatic: The station is ready to work with ATS (Automatic Transfer Switch) units. In case of an external grid failure, the generator will start independently, warm up, and take the load.

• Remote Monitoring: The ability to connect GSM/GPRS modules allows you to track the generator status, fuel level, and grid parameters from a smartphone or PC from anywhere in the world.

• Deep Diagnostics: The controller monitors dozens of parameters, including oil pressure, temperature, battery charge, engine hours, and warns of the need for maintenance.

Heavy Duty All-Weather Enclosure

The unit is supplied in a reinforced soundproof enclosure designed for outdoor operation.

• Quiet Operation: Industrial silencers and sound-insulating materials reduce the noise level, allowing the station to be placed near residential or office buildings (in compliance with sanitary standards).

• Anti-Corrosion Protection: Galvanic coating and powder painting protect the body from rust, snow, and rain for many years.

• Ease of Maintenance: Wide doors on both sides provide easy access to all nodes for changing filters and oil.
