High ambient temperatures reduce a generator's effective power output and increase specific fuel consumption because the engine and cooling system must work harder to dissipate heat. Manufacturers publish derating factors for ambient temperatures above their standard test conditions, which should be applied when sizing for UAE summer operation. Proper siting with clear airflow around the unit and regular cleaning of radiator fins both help offset this effect. Sparkline Group supplies gensets rated with regional ambient conditions in mind and advises on siting during delivery.
