495kVA Cummins or Perkins Diesel Generator GC450S / GP450S

The GC450S is the Cummins-powered version of this Genelite set, and the GP450S is the Perkins-powered version. The detail below is for the GC450S: a three phase, 415V, 50Hz diesel generator set with a Cummins QSZ13-G2, a six cylinder, 13 litre, turbo aftercooled engine running at 1500 rpm. It has a brushless Stamford S4L1D-G4 alternator with AVR.

Key features

• The electronic governor on the GC450S holds engine speed steady as the load changes.
• Harmonic distortion under 5% on the GC450S makes the supply suitable for sensitive electronic equipment.
• The GC450S silenced canopy option is rated at 77.4 dB(A) at 7 m, and it is galvanised and powder coated to resist corrosion.
• The GC450S has a bunded 1650 litre fuel tank, which helps contain any leak.
• The GC450S heavy duty skid base has fork pockets for forklift handling.
• A Deep Sea 7420 MKII controller and a four pole circuit breaker provide monitoring, control and output protection on the GC450S.
• A battery charger and isolator are fitted to the GC450S, so the starting battery stays charged and can be disconnected for servicing.

On the GC450S, the tank gives 24 hours of running at 75% load. Fuel consumption is 89 litres an hour at 100% load, 67 at 75% and 44 at 50%. Engine oil capacity is 45 litres and coolant capacity is 65 litres. Each set comes with a local load-test certificate and a fuel and oil filter kit, and is load and function tested.

What it will run

The GC450S typically suits the combined three phase demand of a large plant or building: production lines, chillers, big pumps and compressors, lifts and building services. Specify it from a site load schedule rather than the nameplate, and have an electrician or engineer assess running loads, motor starting and balance across the phases. The compliance plate on each large motor gives its running and starting load. The GC450S prime rating is for variable load for unlimited hours a year at an average 75% load factor, with 10% overload for one hour in twelve, and its standby rating is for emergency supply at an average 85% load factor, with no overload and a limit of 400 hours a year. A building is connected through a changeover switch installed by a licensed electrician. Send us your load list and we will help with sizing.

The GC450S and GP450S suit large industrial sites, shopping centres and commercial towers, water and wastewater plants, quarries and processing plants, and major construction sites.
