The XQP500 generator set will either meet EU Stage IIIA emission standards or provide low fuel consumption performance for customers in non-regulated territories. A unique feature is the introduction of clutch fan drive technology, where the fan no longer needs to runs continuously at full speed and power. This saves additional fuel, while also lowering noise output; an ideal feature when operating at lower loads, in cooler temperatures, or most importantly, in evenings when noise levels are most noticeable.
