Cummins Power Generation Introduces the Industry's First Tier 4 Final Generator Sets for the Mobile Rental Market

New Mobile Generator Units, From 150 kW to 275 kW, Meet Tier 4 Final Emissions Levels Without the Use of a Diesel Particulate Filter (DPF) MINNEAPOLIS, MN--(Marketwired - November 19, 2013) - Beginning in 2014, mobile diesel generator sets will be among the first applications in the important 175 to 751 horsepower node required to meet new EPA Tier 4 Final emissions regulations, and Cummins Power Generation (NYSE: CMI) will be one of the first manufacturers to have products available for customers. The Tier 4 Final regulations limit mobile generator set emissions to 0.4 grams per kWh of nitrogen oxides (NOx) and 0.02 grams per kWh of particulate matter (PM or soot). These levels represent a 90 percent reduction of the two pollutants from the previous Tier 3, which was introduced in 2005. The new mobile generators from Cummins Power Generation will meet these stringent standards through the least complex aftertreatment package without diesel particulate filters (DPFs), which will benefit the rental operations. The technology behind Cummins' Tier 4 Final compliance Cummins Power Generation was able to meet the new Tier 4 Final regulations through a combination of in-cylinder engine improvements, exhaust gas recirculation (EGR) and selective catalytic reduction (SCR) exhaust aftertreatment. Due to the success of the in-cylinder combustion improvements, none of these first mobile generators being introduced will require a DPF to achieve Tier 4 Final regulations for PM. "By avoiding the need for a DPF, we were able to simplify the aftertreatment package with benefits of lower maintenance for rental operators. An added advantage to in-cylinder combustion improvement is reduced fuel consumption for end users," said Santhosh Sorab, marketing manager for Tier4 Final Product Development of Cummins Power Generation. "As a consequence, our new mobile rental generators are 4 to 5 percent more fuel efficient than previous Tier 3 models and will deliver higher availability and longer running times between service intervals with no increase in package size. They will also deliver the power and performance that our customers have come to expect from Cummins." The first Tier 4 Final generator sets for the rental market from Cummins Power Generation will be the C150D2R generator set, standby rated at 150 kW, and the C200D2R generator set, standby rated at 200 kW. Both units will be available for delivery by Q3 2014. The C275D2R generator set, standby rated at 275 kW, is scheduled to be available beginning in Q4, 2014. Cummins Power Generation displayed its 200kW Tier 4 Final generator at the 2013 POWER-GEN International show in mid-November. New generator features include simplified paralleling for fleet flexibility The Tier 4 Final certified mobile generators will feature switchable 60/50Hz dual frequency operation with multiple voltage configurations of 208V, 240V and 480V in three-phase, and 240V in single-phase. The units will also feature the new PowerCommand 3.3 controller (PCC) with both paralleling and advanced master-less load demand capabilities. "We're excited about this feature, which is the first in this power range. Rental operators are always looking for ways to improve utilization of their fleets. The new PCC 3.3 will support this, by offering a simple way to scale power by paralleling smaller sets," said Sorab. "With master-less load demand capability, the controller can smartly manage power from paralleled generators to match varying load patterns, offering additional flexibility and fuel savings for end users" The packaged generators will also include a diesel exhaust fluid (DEF) tank and monitoring unit that controls the dispensing of DEF into the SCR to cut emissions of NOx. The normal consumption of DEF is less than 4 percent of fuel consumption, and the DEF reservoir and the fuel tank are sized appropriately to ensure uninterrupted 24 hour runtime. "These new flexible and fuel-efficient mobile rental generators are the result of more than two years of design engineering and rigorous real-world testing," said Sorab. "Cummins visited several customer sites and interviewed rental fleet managers, operators and end users, found solutions to customer concerns and tested the design results under real-world operating conditions in the field. The result is a proven line of new Tier 4 Final rental generators that will be easy and economical to operate, quiet and clean, and deliver the power, performance and reliability that rental dealers need." Please visit the Web site: http://www.rental.tier4answers.com/ About Cummins Power Generation Cummins Power Generation, a subsidiary of Cummins Inc.
