copy of Pramac GPW 45 Y diesel generator – BASIC PLUS 400V

The Pramac GPW 45 Y 400V is a more powerful model in Pramac’s professional diesel range, designed for sites requiring a higher three-phase power reserve, stable operation under heavy loads, and a generator capable of sustained daily use. The model delivers 38.0 kW of maximum power and 34.4 kW of rated power, making it well-suited for industrial sites, construction sites, service and technical centres, farms, engineering facilities, warehouse complexes and backup power for commercial premises where a reliable three-phase power source is essential.

This model uses a Yanmar 4TNV98CT-IPGE diesel engine with a displacement of 3319 cm³. This is a 4-cylinder in-line engine with natural aspiration, which complies with the Stage V environmental standard. This version also features an electronic speed governor, which is a significant advantage for a generator of this class, as it allows for more precise maintenance of stable operating parameters under variable loads. Liquid cooling maintains a reliable thermal regime during prolonged operation, and the engine configuration itself is well suited to sites where the generator is expected not just to start up once, but to provide reliable and predictable performance.

Start-up is via an electric starter powered by a 12 V battery system, making the model suitable for both emergency scenarios and day-to-day operation. This configuration allows the generator to be brought into operation quickly, which is particularly important at sites where even a brief power cut can affect the operation of machinery, pumps, ventilation, automation systems or other equipment.

From an electrical standpoint, the model also looks very impressive. The generator operates at 400/230 V, 50 Hz and is three-phase. It is fitted with a Mecc Alte ECP32 2S4 C brushless alternator with insulation class H and IP23 protection rating. The maximum current is 69 A and the rated current is 62 A, so the generator is suitable for powering a more substantial three-phase load than the lower-end models in the series. This allows it to be used for equipment in workshops, on construction sites, in service areas or at commercial premises with mixed consumption.

Another strong point of the Pramac GPW 45 Y 400V is the combination of power and adequate fuel autonomy. The documentation specifies a consumption of 7.43 l/h at 75% load and 10.55 l/h at 100% load. For the 80-litre internal tank, this equates to 10.77 hours of operation at 75% load. Based on consumption at full load, the estimated operating time is approximately 7.58 hours. This figure is well-suited for work shifts, backup power and scenarios where it is important to maintain a balance between power and fuel costs.

The PDF separately lists the available control panel options — ACP and MPP. The ACP version supports AMF, i.e. automatic start-up in the event of a mains failure, as well as full monitoring and protection of the generator. The MPP version allows the unit to be used in parallel operation configurations. This makes the model more flexible in terms of integration into real-world backup or main power supply systems. The file also specifies that the socket panel is optional and the socket set is determined at the time of ordering, so the connection configuration can be tailored to a specific site. :contentReference[oaicite:3]{index=3}

From a design perspective, the model is housed in a soundproof and weatherproof enclosure, which helps to reduce noise whilst protecting the generator from external influences. The design features large side doors for convenient service access, anti-vibration mounts, a sturdy steel base, a crane lifting point and a robust top lifting bridge. This makes the generator more practical for transport, installation and regular maintenance in real-world operating conditions.

The model measures 2200×1020×1423 mm and weighs 987 kg. The noise level, according to the documentation, is 61/90 dB, i.e. 61 dB at 7 m and 90 dB LwA. For a diesel generator of this class, this is a good figure, allowing the model to be used not only on rough industrial sites but also in technical and commercial areas where acoustic comfort is also important.

The Pramac GPW 45 Y 400V is an excellent choice for those who need a powerful, modern and well-balanced diesel generator with a Yanmar Stage V engine, electronic speed control, a reliable three-phase system, good autonomy and the ability to flexibly select a control configuration for specific tasks.
