PRAMAC GRW280V 3 PHASE DIESEL GENERATOR

Description

GRW Series – Industrial Diesel Generators

Low Noise. Heavy-Duty Build. Engineered for Long-Duration Performance.

The GRW Series is a robust family of industrial diesel generators developed for sites that require low noise, extended running autonomy, and dependable performance in all conditions. Purpose-built for commercial facilities, utilities, mining, construction, data centres, and mission-critical environments, the GRW range delivers reliable 3-phase power across a broad output spectrum—making it suitable for anything from medium-duty industrial loads to large, complex installations.

With corrosion-resistant galvanized steel canopies and fully bunded heavy-duty baseframes, every GRW generator is engineered to withstand aggressive environments, harsh weather, and long operating cycles. The enclosures incorporate acoustic insulation and integrated exhaust silencers to ensure quiet performance even during high load demand. Extra Silent versions provide further noise reduction, making the GRW Series ideal for noise-sensitive locations such as urban worksites, commercial precincts, and events.

Large internal fuel tanks deliver impressive autonomy, supporting long uninterrupted operation without frequent refuelling. Mid-range models typically offer over 24 hours of runtime at 75% load, while higher-capacity models benefit from even larger tanks with extended operating windows. This makes the series particularly well-suited to locations where access is limited or where continuous power is essential.

Premium engine options include Perkins and Volvo, chosen for their reliability, fuel efficiency, and strong performance in demanding industrial environments. These engines are paired with high-efficiency brushless alternators offering excellent voltage stability, low waveform distortion, and strong motor-starting capability. Dual-frequency capability and optional voltage selector switches are available across the range, giving the GRW Series exceptional flexibility for rental fleets, multi-region operations, and variable-load environments.
