Thirteen mobile generators from Ingersoll Rand are built with a compact design and environmentally friendly features. Designed to hold at least 110-percent capacity of all fuel, oil and coolant contained within the generator, the units offer minimal water entrainment, single fuel tanks with double-wall protection and minimum 24-hour prime-power run times. A reduced footprint makes the units easy to maneuver on the jobsite. AREP technology built into the alternators delivers maximum motor-starting capability, says I-R. Estimated list price: $12,000 to $141,000.
