GRW405V 400kVA Rental Diesel Generator

Description

Pramac GRW405V – 400 kVA Rental Diesel Generator

Volvo power. Leroy Somer output. 1180 litre tank. Rental tough.

The GRW405V diesel generator delivers 400 kVA / 320 kW emergency standby and 365 kVA / 292 kW prime power from a Volvo TAD1352GE, a six cylinder, 12.78 litre, turbocharged, water-cooled Stage IIIA engine running at 1500 RPM with electronic governor. Output is delivered through a brushless Leroy Somer LSA 46.3 L11 alternator at 400/230 V, 50 Hz, three phase, 0.8 power factor, with class H insulation, IP23 protection, Protection System 2 winding treatment, 12 winding leads and electronic voltage regulation held inside 0.5%. Maximum current is 577 A behind an 800 A circuit breaker. The set is switchable to 60 Hz for 1800 RPM operation.

The canopy is built from modular panels of zinced metal sheet tested to more than 1000 hours of salt spray, with gasketed access doors and lockable handles on each side, washable fireproof soundproofing and an integrated residential exhaust silencer with rain flap, giving 67 dB(A) at 7 metres and a guaranteed sound power level of 97 dB(A). The heavy-duty powder coated base frame is fully bunded to retain 110% of the set fluids and carries integrated fork pockets, a pull bar and a single lifting point with rung and handle on both sides. The unit measures 4165 x 1500 x 2130 mm and weighs 4515 kg.

The integrated 1180 litre metal fuel tank runs 19.98 hours at 75% prime power and 15.69 hours at full load, with a refilling point on each side and a six way fuel valve for connection to an external tank. The ACP automatic control panel carries the AMF function, full genset monitoring and protection, a detailed event log with time and date, emergency push button, analogue fuel level meter and mechanical hour counter, differential protection, battery charger and two wire remote start/stop. An MPP modular parallel panel is available as an alternative.
