Pramac GDW 90 P (B15) 400V diesel generator

ThePramac GDW 90 P 400/230 V Stage IIIA is a powerful three-phase diesel generator designed to provide a stable power supply for facilities with heavy loads. The model delivers 72.7 kW of maximum power and 65.8 kW of rated power, making it well-suited for production sites, technical facilities, warehouse infrastructure, service areas, construction sites and backup power systems.

The generator is equipped with a Perkins 1104D-E44TAG1 diesel engine with a displacement of 4,400 cm³, featuring turbocharging and an electronic speed governor. This configuration helps maintain operating parameters more accurately and ensures reliable operation under load during prolonged use. Liquid cooling ensures a stable thermal regime, which is particularly important for a generator of this power class.

The model is equipped with an electric starter and a 12 V / 80 Ah battery, ensuring quick and convenient starting. This is a practical solution for backup power systems where the readiness of equipment for immediate operation is critical. The 400/230 V three-phase configuration allows the generator to power a wide range of equipment — from engineering systems and pumps to production lines, ventilation and lighting.

The generator uses a Mecc Alte ECP32-2L4 C brushless alternator with insulation class H and protection rating IP23. The model’s maximum current is 131 A, and fuel consumption at 100% load is 20.38 l/h. This makes the model a reliable solution for critical power supply to facilities where stability and power reserve are essential.

One of the strengths of this version is its large 350-litre internal fuel tank, which ensures long-term autonomous operation without frequent refuelling. In the Canopy version, the generator measures 2757×1120×1846 mm, weighs 1406 kg and has a noise level of 68/97 dB. The Pramac GDW 90 P 400/230 V Stage IIIA is an excellent choice for sites requiring a powerful Perkins turbocharged diesel generator with electronic speed control and the capacity for intensive operation.
