Pramac GPW 45 Y - BAU 400V diesel generator

The Pramac GPW 45 Y – BAU 400V is a three-phase diesel generator designed for sites where a stable power supply, reliable operation under load and good running time are required, without any unnecessary operational complications. The model delivers a maximum power output of 38.0 kW and a rated power output of 34.4 kW, and is therefore well suited to construction sites, production areas, plant rooms, service centres, agricultural premises, storage areas and the emergency power supply for commercial premises where a significant reserve capacity for three-phase loads is already required.

At the heart of the generator is a Yanmar 4TNV98CT-IPGE engine, compliant with Stage V emissions standards, with a displacement of 3319 cm³. It is a 4-cylinder in-line turbocharged diesel engine that runs at 1,500 rpm and features electronic speed control. For a generator of this class, this configuration is a major advantage, as it helps to maintain operating parameters more precisely and stably under varying loads. Liquid cooling ensures reliable temperature control during continuous operation, and the engine’s design is well-suited to daily professional use. :contentReference[oaicite:6]{index=6}

The model is fitted with an electric start via a 12 V battery system, allowing the generator to be started conveniently on site, both in emergency power mode and during regular operation. This design is well suited to technical and commercial scenarios where, following a failure of the mains supply, power must be restored quickly and without additional effort on the part of staff. :contentReference[oaicite:7]{index=7}

The model’s electrical specifications are also well suited to professional use. The generator operates at a voltage of 400/230 V, a frequency of 50 Hz and has three phases. It is fitted with a brushless Mecc Alte ECP32 2S4 C generator with insulation class H and protection rating IP23. The maximum current is 69 A, the rated current is 62 A and the automatic circuit breaker is rated at 63 A. This enables the model to be used safely with three-phase and single-phase appliances, pumps, ventilation systems, lighting, service equipment and other loads that require a stable power source. :contentReference[oaicite:8]{index=8}

In terms of running time, the Pramac GPW 45 Y - BAU 400V is very practical. At 75 per cent load, fuel consumption is 7.43 l/h; at 100 per cent load, it is 10.55 l/h. The documentation specifies an operating time of 10.77 hours at 75 per cent load for the internal 80-litre fuel tank. At full load , the approximate operating time is around 7.58 hours. For a model in this class, this is a good figure, enabling the generator to be used both as an emergency power supply and for longer operating cycles without the need for constant refuelling. :contentReference[oaicite:9]{index=9}

The documentation for this model lists the available ACP and MPP panels separately. ACP supports automatic operation in the event of a mains failure, whilst MPP is designed for more complex circuits involving parallel operation. It is also noted that the socket panel is optional and that the socket set is specified at the time of ordering. This means that the model can be flexibly adapted to the specific location and the desired type of load connection. :contentReference[oaicite:10]{index=10}

In terms of design, the generator is housed in a soundproof and weatherproof enclosure, which helps to reduce noise and protects the unit from external influences. The design features large side doors, vibration-damping supports, a robust steel base, a crane lifting point and an upper lifting bridge. This makes the generator more practical for transport, installation and maintenance under real-world operating conditions. The model’s dimensions are 2200 × 1020 × 1423 mm, and it weighs 987 kg. The noise level of the canopy version is 61/90 dB, which is a good figure for a generator in this power class. :contentReference[oaicite:11]{index=11}

The Pramac GPW 45 Y – BAU 400V is a high-performance solution for anyone requiring a modern diesel generator with a Stage V Yanmar engine, electronic speed control, good running time and a reliable three-phase unit. If there is a separate sheet detailing additional features for the BAU version, these can be incorporated into the description as separate features without mixing them in with the basic technical specifications.
