Pramac GDW 280 V (B25) 400 V diesel generator

ThePramac GDW 280 V 400/230 V is a powerful three-phase diesel generator designed for facilities with high energy consumption, where power stability, equipment durability and the ability to operate continuously under heavy loads are essential. The model delivers 220.0 kW of maximum power and 200.0 kW of rated power, making it suitable for production sites, logistics centres, warehouse complexes, technical infrastructure, large service facilities, pumping stations, ventilation systems and backup power supplies for critical commercial or industrial facilities.

This version uses a Volvo TAD841GE diesel engine with a displacement of 7,700 cm³. It is a 6-cylinder in-line turbocharged power unit designed for stable power output during continuous operation. For a generator of this class, it is important that the engine is combined with a liquid cooling system, which helps maintain a reliable thermal regime during continuous operation. This configuration is well suited to facilities where the power system must operate predictably and without dips under high load.

A distinct advantage of this model is the electric start via a 24 V battery system. This is particularly relevant for a powerful generator, as such a starting system enhances starting reliability and is better suited to equipment designed for heavy loads and critical tasks. In practical use, this means easier starting, faster readiness for operation and more practical use of the generator in standby mode, when it is essential to supply power to critical systems without delay.

The Pramac GDW 280 V operates at 400/230 V, 50 Hz and has 3 phases, making it suitable for powering a full three-phase load. The model is fitted with a Mecc Alte ECO38 2M4 C brushless alternator with insulation class H and protection rating IP23. The maximum current is 397 A, allowing the unit to be used for powerful industrial equipment, compressor systems, pumping stations, ventilation units, large-area lighting and other energy-intensive infrastructure.

Another key strength of this model is its extended range of applications. The documentation specifically states that the generator can also be used in a Data Centre Power configuration, where its output is also 200.0 kW. This means that the model can be considered not only as a classic solution for backup or primary power supply, but also as an option for facilities with heightened requirements for power supply reliability, particularly for data centres and similar technical infrastructure. This focus makes the model even more versatile for professional use. Details regarding the DCP are provided separately on page 2 of the file. :contentReference[oaicite:3]{index=3}

In terms of autonomy, the model also looks practical. Various fuel tank options are available for it, and a 600-litre configuration is specified for the internal version. With a fuel consumption of 53.30 l/h at 100% load, the estimated operating time is approximately 11.26 hours. At 75% load, consumption is 41.79 l/h, which is also important for more accurate planning of operation, refuelling and fuel costs during daily operation or standby duty.

In the Canopy soundproof version, the generator measures 3702×1200×2050 mm, weighs 2563 kg and has a noise level of 68/97 dB. For sites with stricter noise requirements, the file also includes the Extra Silent version, where noise levels are reduced to 64/94 dB. Thanks to the combination of a powerful Volvo engine, a 24-volt starting system, high current reserve, three-phase configuration and suitability for data centre applications, the Pramac GDW 280 V 400/230 V is a robust solution for large technical and industrial facilities where power supply reliability is of paramount importance.
