Pramac GPW 20 P - BAU 400V diesel generator

ThePramac GPW 20 P - BAU 400V is a three-phase diesel generator designed for sites where more than just a backup power supply is required – a more robust solution for day-to-day technical operations. The model delivers 17.6 kW of maximum power and 16.0 kW of rated power, making it well-suited for workshops, construction sites, service areas, warehouses, technical facilities and small commercial premises where stability, autonomy and the generator’s readiness for regular operation are essential. :contentReference[oaicite:0]{index=0}

This model uses a Stage V-compliant Perkins 404J-22G diesel engine with a displacement of 2220 cm³. It is a 4-cylinder in-line engine with natural aspiration, operating at 1500 rpm, featuring a mechanical speed governor and liquid cooling. This configuration is well suited to a generator of this class, as it combines reliability, predictable performance under load and compliance with modern environmental requirements. Starting is via an electric starter powered by a 12 V battery system, making the model suitable for both emergency scenarios and everyday use. :contentReference[oaicite:1]{index=1}

The electrical components of the model are also well-balanced for professional use. The generator operates at 400/230 V, 50 Hz and is three-phase. It uses a Mecc Alte ECP28 M4 C brushless alternator with insulation class H and protection rating IP23. The maximum current is 32 A, the rated current is 29 A, and the circuit breaker is rated at 32 A, making the generator suitable for powering three-phase and single-phase equipment, power tools, pumps, lighting and other loads requiring a stable power supply. :contentReference[oaicite:2]{index=2}

One of the notable advantages of the BAU version is its extended equipment, which makes the model more practical and ready for real-world operation on site. This configuration includes an MBS (main battery switch), a TWF (three-way fuel valve), a WSP (water-separating diesel filter), BFB — plastic frame protection, GDH — documentation holder, RCDB — Type B FI protection, and QFC — quick-connect fitting for an external tank. It is precisely these details that clearly demonstrate the difference between the BAU and more basic versions: the generator becomes not just a power source, but a more adaptable solution for technical operation, servicing, safe connection and operation in more challenging conditions. The BAU specification for this model also includes a Dummy-Load for low-load mode, which helps to reduce the risks associated with operating the diesel generator at low load. :contentReference[oaicite:3]{index=3}

The practicality of the BAU version is also clearly evident in the load connection. For this model, the BAU slide specifies a set of sockets: 400 V — 1 x 16A, 1 x 32A (30mA), 1 x 63A (500mA), as well as 230 V — 1 x Schuko. This configuration is well suited to technical, construction and service facilities where different types of equipment need to be connected simultaneously. Additionally, for the BAU version, the slide lists ETB options, insulation monitoring and IT/TN network switching, which may be relevant for specific usage scenarios and power supply requirements. :contentReference[oaicite:4]{index=4}

In terms of autonomy, the generator also looks very promising. With a fuel consumption of 3.96 l/h at 75% load, the model can operate for 20.20 hours from the 80-litre internal tank. At 100% load, consumption is 5.53 l/h, and the estimated running time is around 14.47 hours. For a diesel generator of this class, this is a very good figure, allowing the unit to be used both in standby mode and for longer operating cycles without the need for frequent refuelling. :contentReference[oaicite:5]{index=5}

In the soundproof version, the model measures 2200×1020×1313 mm and weighs 778 kg. According to the technical data for the canopy series, the noise level is 59/88 dB, whilst the BAU slide for this model specifies 60 dB at 7 m; therefore, when marketing the BAU version, it makes sense to emphasise that the generator remains sufficiently quiet for use near work areas, technical rooms and commercial premises where noise is also a consideration. :contentReference[oaicite:6]{index=6}

The Pramac GPW 20 P - BAU 400V is not just a compact three-phase diesel generator, but a more advanced BAU version with a focus on safety, the fuel system, ease of servicing and adaptation to real-world operation on site. That is precisely why this model is well suited to situations where a generator is expected to deliver not only stable power but also more sophisticated features for daily professional use.
