Upgraded Generator Line Meets Emission Standards

Doosan Infracore Portable Power has upgraded its IR mobile generator line and now has 10 models ranging from 25 kVA to 570 kVA, all of which it says comply with U.S. EPA emissions regulations. The G25 and G40 are powered by Mitsubishi engines certified to EPA. Tier 4 interim requirements in effect until 2013 when Tier 4 final standards become effective for this horsepower category. These new models, rated at 25 kVA and 35 kVA respectively, replace EPA Tier 2 versions with the same model designation. The G70 and G90, rated at 72 kVA and 94 kVA respectively, are powered by John Deere engines certified to EPA Tier 3 requirements in effect until 2012 when Tier 4 interim standards become effective. These new models replace the G60 and G80 and feature as much as 24% higher output, in addition to cleaner emissions.

The G145, G185 and G240 models, powered by John Deere engines, and the G290, powered by Cummins, are Tier 3 certified and rated at 144 kVA, 183 kVA, 239 kVA and 290 kVA respectively. They will continue until 2011, at which time Tier 4 interim standards for this horsepower category become effective. At the top of the range the G450 and G570, powered by Cummins and rated at 456 kVA and 570 kVA respectively, have been in production since 2007 with EPA Tier 2 certification, the current requirement for engines rated greater than 751 hp (560 kW). In 2011, the Tier 4 interim standard for this horsepower category becomes effective.

The product range offers features such as a quiet, rugged enclosure built from heavy-gauge steel and finished with a 13- stage powder-coat process; AREP (Auxiliary Regulation Excitation Principle) excitation, claimed to provide an advantage in starting bigger motors with smaller generators; 24-hour onboard fuel capacity and a containment system that can prevent spillage of 110% of all fuel, oil and coolant volume; and heavy-duty skid bases and running gear components for towing on- or off-road. The G25 through G185 models have a protection feature that prevents operators from switching voltage during operation—a common cause of downtime and expensive component failure.
