Pramac GPW 35 Y - BAU 400V diesel generator

ThePramac GPW 35 Y - BAU 400V is a three-phase diesel generator designed for sites where more is required than just a backup power source; it is a version better suited to daily operation, featuring additional equipment, a higher level of safety and more reliable performance in real-world conditions. The model delivers 30.8 kW of maximum power and 28.1 kW of rated power, making it well-suited for construction sites, service facilities, technical bases, farms, warehouses, industrial areas and backup power for commercial premises where a more substantial reserve for three-phase loads is required.

The power unit of the model is a Yanmar 4TNV98C-IPGE Stage V diesel engine with a displacement of 3319 cm³. This is a 4-cylinder in-line engine with natural aspiration, operating at 1500 rpm and featuring an electronic speed governor. This configuration is particularly well-suited to a generator of this class, as it ensures more stable operation under variable loads and makes the model suitable not only for occasional standby use but also for regular operation. Liquid cooling maintains a reliable temperature regime, which is particularly important during prolonged operation under load. :contentReference[oaicite:4]{index=4}

The model is equipped with an electric start powered by a 12 V battery system, so the generator is easy to start and well-suited for scenarios where power needs to be restored quickly following a mains power failure. This starting method is particularly convenient for technical facilities where equipment must be ready for operation without any additional action from staff. :contentReference[oaicite:5]{index=5}

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 ECP32 1S4 C brushless alternator with insulation class H and protection rating IP23. The maximum current is 56 A, the rated current is 51 A, and the circuit breaker is rated at 50 A. This allows you to confidently connect three-phase and single-phase equipment, tools, pumps, lighting, service systems and other technical loads that require a stable power supply. :contentReference[oaicite:6]{index=6}

One of the strengths of the Pramac GPW 35 Y - BAU 400V is that the BAU version makes the generator significantly more practical for real-world use on site. This configuration includes an MBS (main battery switch), a TWF (three-way fuel valve), a WSP (water-separating diesel filter), a BFB (plastic frame protection), GDH — documentation holder, RCDB — Type B RCD, and QFC — quick-connect fitting for an external tank. It is these elements that clearly demonstrate the BAU version’s distinction from simpler versions: the generator becomes safer to connect, more practical to service, and better suited to intensive technical operation.

Load connection is also important for the BAU version. The configuration of this series includes 400 V — 1 x 16A, 1 x 32A (30mA), 1 x 63A (500mA), as well as 230 V — 1 x Schuko. This connection scheme makes the model suitable for construction, technical and service scenarios where it is necessary to operate simultaneously with different types of equipment. Additionally, for the BAU version in this series, ETB, insulation monitoring and IT/TN network switching may also be relevant if required for a specific application at the site.

In terms of autonomy, the model also performs very well. Fuel consumption is 6.18 l/h at 75% load and 8.69 l/h at 100% load. With an 80-litre fuel tank, the documentation specifies 12.94 hours of operation at 75% load, whilst the estimated operating time at full load is approximately 9.21 hours. This is a good figure for a generator of this power class, allowing it to be used both as a backup power source and as a working solution for longer shifts without the need for frequent refuelling. :contentReference[oaicite:7]{index=7} :contentReference[oaicite:8]{index=8}

It is also worth mentioning the Dummy-Load, which is an important practical addition to the BAU series in low-load modes. Its inclusion is useful for reducing the risks associated with operating a diesel generator set at low load, so for technical and service scenarios, this is not merely a marketing gimmick but a genuinely useful feature of the specification.

The model measures 2200×1020×1506 mm, and for the BAU series, it weighs approximately 1190 kg. The noise level for this version is 61 dB at 7 m, which is well suited to a professional generator of this class and allows it to be used not only on rough industrial sites but also in technical or commercial areas where noise is also a consideration. For the GPW35Y series, the canopy version in the technical PDF also has similar dimensions and acoustic characteristics, confirming the practicality of this design. :contentReference[oaicite:9]{index=9}

The Pramac GPW 35 Y - BAU 400V is an excellent choice for those who need not just a three-phase diesel generator, but specifically the BAU version with an emphasis on safety, fuel efficiency, ease of maintenance and practical adaptation to real-world operating conditions. This is precisely why this model stands out from the simpler versions in the series and is better suited for professional daily use.
