Pramac GDW425B/FNE | 341kW Diesel Generator | Three-Phase | Baudouin Engine

The Pramac GDW425B/FNE is a professional industrial diesel generating set engineered for applications where dependable high-capacity three-phase power is essential.

At the heart of the generator is the Baudouin 6M21G2D0/S, a 12.5-litre six-cylinder turbocharged and aftercooled diesel engine operating at 1500rpm. The engine features electronic speed governing, water cooling and a 24V electric starting system.

The generator provides 426.3kVA / 341kW Emergency Standby Power and 385kVA / 308kW Prime Power, making it suitable for both emergency backup installations and extended operation under variable electrical loads.

Baudouin Industrial Diesel Engine

The Baudouin 6M21G2D0/S combines strong power output with rugged industrial construction and dependable operation.

Key engine characteristics include:

• 12,540cm³ / 12.5-litre displacement
• Six cylinders in-line
• Turbocharged and aftercooled aspiration
• Electronic speed governor
• Water-cooled design
• 24V electric starting system
• 30-litre oil capacity
• 25-litre coolant capacity

The engine develops up to 385kWm gross mechanical power in ESP operation and 350kWm in PRP operation.

Mecc Alte Alternator

Electrical generation is handled by the Mecc Alte ECO40 1S4 C brushless alternator.

The alternator provides a 440kVA standby rating at 27°C and a 400kVA continuous nominal rating at 40°C.

It offers approximately 94.2% efficiency at full load, Class H insulation, IP23 protection and approximately ±0.5% voltage tolerance.

Fuel Consumption & Runtime

Fuel consumption is approximately:

61.92 litres per hour at 75% Prime Power

82.07 litres per hour at 100% Prime Power

A range of optional fuel tanks is available with capacities from 650 litres up to 4,000 litres.

Depending on the selected tank, approximate runtime at 75% PRP ranges from 10.50 hours to 64.60 hours.

Automatic Mains Failure Control

The optional ACP Automatic Control Panel provides Auto Mains Failure functionality for standby installations.

The system offers full generator monitoring and protection, detailed event and performance logging, remote control compatibility and optional I/O expansion.

Parallel Generator Operation

For larger installations, the optional MPP Modular Parallel Panel allows the GDW425B/FNE to operate in parallel with other generating sets.

Up to 32 generator sets can be configured for parallel operation, making this model suitable for large industrial systems, load sharing and redundancy applications.

Open & Canopy Versions

The GDW425B/FNE is available in both open-frame and weatherproof canopy configurations.

The canopy version uses galvanized sheet-steel construction and quality acoustic insulation to protect the generator in demanding environments while reducing operating noise.

The standard canopy provides approximately:

• 97 dB(A) guaranteed sound power
• 78 dB(A) sound pressure at 1 metre
• 68 dB(A) sound pressure at 7 metres

An Extra Silent canopy is also available with a guaranteed sound power level of approximately 94 dB(A).

Typical Applications

The Pramac GDW425B/FNE is suitable for industrial facilities, manufacturing plants, warehouses, commercial buildings, construction projects, utilities, infrastructure, agriculture, emergency standby systems and prime power installations.

With its combination of Baudouin engine technology, Mecc Alte alternator performance and 341kW standby output, the GDW425B/FNE provides a dependable high-capacity solution for demanding three-phase power requirements.
