DIESEL GENERATOR DE-440BDS

Diesel Generator DE-440BDS: Industrial Power of 320 kW with Baudouin Engine

For large industrial facilities, logistics centers, grain elevators, and medical institutions, the issue of energy security is particularly acute. The DE-440BDS diesel generator with a nominal power of 320 kW (400 kVA) and a maximum power of 352 kW (440 kVA) is the “heavy artillery” in the Darex Energy lineup.

This model is designed for 24/7 operation. It is capable of ensuring full autonomy for a factory, shopping mall, or residential complex. At the core of the unit lies the legendary French Baudouin engine, which guarantees the stability of output parameters even under critical loads.

Power Unit: Baudouin 6M21G440/5

The main advantage of the DE-440BDS is the 6-cylinder inline engine Baudouin 6M21G440/5 with a displacement of 12.54 liters. This is a low-speed (1500 rpm) industrial motor, the resource of which before overhaul is calculated in tens of thousands of engine hours.

Key engine features:

• Electronic Control (ECU): The engine management system instantly reacts to load changes, maintaining the rotational speed with high precision. This eliminates voltage “sags” when starting powerful pumps or machine tools.

• Turbocharged with Intercooler: The “air-to-air” air supply system ensures maximum fuel combustion efficiency.

• Fuel Efficiency: Despite its impressive power, the generator consumes a reasonable amount of fuel:

  • At 50% load: ~43.2 L/h

  • At 75% load: ~63.5 L/h

  • At 100% load: ~85.5 L/h

• Winter Package: The engine is equipped with a coolant heating system (Water Jacket Heater), which ensures a confident start in frosts down to -30°C.

Alternator and Voltage Stability

The generator is equipped with a modern synchronous alternator with 100% copper winding. The SHUNT excitation system and Automatic Voltage Regulator (AVR SX460 or equivalent) guarantee output voltage stability of 400V with a deviation of no more than ±1%.

Insulation class H and IP23 protection allow the alternator to withstand short-term overloads (up to 110% for 1 hour) without the risk of overheating the windings. This is critically important for facilities with high inrush currents.

Automation and Control: Datakom

The power station is managed via the Datakom D-300 controller (or equivalent DSE), which features an intuitive interface. System functionality:

• Automatic Transfer Switch (ATS): The generator monitors the grid availability itself. When the electricity goes out, it starts in 10-15 seconds and takes on the load. When the grid returns, it correctly switches consumers back and cools down before stopping.

• Telemetry: All parameters are displayed on the screen: oil pressure, antifreeze temperature, phase voltage, current, frequency, fuel level.

• Protection: In case of alarm readings (low oil pressure, overheating, current overload), the controller will instantly stop the engine, preventing a breakdown costing thousands of dollars.

Construction and Soundproofing

The generator is supplied in an all-weather Euro-standard sound-absorbing enclosure.

• Fuel Tank: A built-in tank with a volume of 850 liters ensures long autonomous operation (more than 12 hours at average load) without refueling.

• Silence: Thanks to high-quality insulation materials and an industrial silencer, the noise level is reduced to norms acceptable for the city.

• Corrosion Resistance: The enclosure is coated with powder paint and galvanized, which protects the metal from rust even when installed outdoors in snow and rain.
