Pramac GDW 220 I (B25) 400V diesel generator

ThePramac GDW 220 I 400/230 V is a powerful three-phase diesel generator designed for facilities requiring a stable, stand-alone power supply with high reliability, a good power reserve and reliable operation under heavy-duty conditions. The model delivers 176.0 kW of maximum power and 160.0 kW of rated power, making it suitable for manufacturing plants, warehouse complexes, logistics centres, service facilities, engineering infrastructure, pumping stations, ventilation systems and backup power for large commercial or industrial sites.

This version uses an FPT NEF67TM7 diesel engine with a displacement of 6,700 cm³. This is a 6-cylinder in-line turbocharged power unit, well-suited for stable, long-term operation under heavy loads. The model is equipped with a mechanical speed governor, ensuring predictable operation in daily use. Liquid cooling helps maintain a reliable temperature regime, which is particularly important for a generator of this power class, designed for continuous load and operation in critical power supply systems.

A separate practical advantage is the electric start from a 12 V battery system. This configuration simplifies starting the unit and makes the model suitable for backup scenarios where power needs to be restored quickly following a mains failure. For facilities with critical loads, this is very important, as it allows for the rapid restoration of automation, lighting, ventilation, pumps, server rooms, refrigeration equipment or other systems that must not be left without power for long periods.

The Pramac GDW 220 I operates at 400/230 V, 50 Hz and has 3 phases, making it suitable for fully powering a high-power three-phase load. The model is fitted with a Mecc Alte ECO38 2S4 C brushless alternator with insulation class H and IP23 protection rating. The maximum current is 318 A, allowing this unit to be used to power production lines, compressor systems, pumping stations, ventilation, engineering equipment and other energy-intensive three-phase loads.

A significant advantage of this model is its good fuel autonomy. Several fuel tank configurations are available, with a 600-litre option provided for the internal version. At a fuel consumption rate of 40.81 l/h at 100% load, the generator can operate for approximately 14.70 hours. At 75% load, fuel consumption is 30.99 l/h, which is also important for more realistic planning of daily operating schedules, fuel costs and refuelling intervals. For large facilities, this enables better planning of the operation of the backup or main power supply system.

In the Canopy soundproof version, the model measures 3702×1200×2050 mm, weighs 2215 kg and has a noise level of 68/97 dB. For sites where a lower noise level is important, the catalogue also features the Extra Silent version, which has improved acoustic performance down to 64/94 dB. This offers greater flexibility when selecting a version for specific installation conditions — from production areas to technical sites with heightened noise requirements.

The Pramac GDW 220 I 400/230 V is a robust solution for those requiring a powerful FPT generator with a high current reserve, a reliable three-phase unit, electric start, and the ability to operate stably under heavy loads. The model is well suited for both backup and primary power supply where the continuity of the entire facility’s operation depends on the reliability of the power supply.
