Based on Cummins 9 liter inline 6-cylinder diesel engine, DSHA low-emissions generator sets operate at 60 Hz and are intended for standby and prime power use. Model DSHAA is standby-rated at 150 kW and prime-rated at 135 kW, Model DSHAB is rated standby/prime 175/160 kW, and Model DSHAC is rated 200/180 kW. Series also features PowerCommand[R] digital control system with automatic remote start/stop, frequency/voltage regulation, message display, and auto shutdown.
MINNEAPOLIS - Cummins Power Generation is the first manufacturer to introduce a new series of 150 kW, 175 kW and 200 kW low-emissions diesel generator sets that comply with new EPA Tier 3 standards for nonroad (mobile) applications. In addition, these generator sets meet the EPA Tier 3 requirements for stationary generators that are scheduled to go into effect January 1, 2007.
"With the early introduction of the DSHA low-emissions generator sets, Cummins Power Generation continues its commitment to clean air with another first," says Gary Lafine, Product Director, low-range generators. "This builds on our track record of leadership in delivering high-performance generator products to our customers while meeting or exceeding our environmental commitments."The new generator sets are based on a Cummins 9-liter inline 6-cylinder diesel engine that offers very low emissions and fast transient response to load changes. The 60 Hz generator sets are intended for standby and prime power use in a wide range of applications and are backed by the Cummins global service network.
Cummins met the challenge of the Tier 3 reductions by capitalizing on its extensive expertise in combustion research. By focusing on in-cylinder technology improvements, Cummins was able to reduce NOx by 40 percent from Tier 2 levels without the use of complex external hardware or exhaust aftertreatments that increase installation, operation or maintenance costs for end-users. This design strategy has resulted in low-emissions generator sets with a smaller footprint, better performance, less complexity and more reliability.
The Tier 3 engine for this generator set series features a full-authority electronic control module and a high-pressure, common-rail fuel injection system that delivers improved response to transient loads, a sound reduction of 5 db(a) and better cold starting. The improved engine management system maintains an optimum balance between load demands, fuel-efficiency and emissions control.
The DSHAA generator set is standby-rated at 150 kW; and prime-rated at 135 kW. The DSHAB generator set is standby-rated at 175 kW; and prime-rated at 160 kW. The DSHAC is standby-rated at 200 kW; and prime-rated at 180 kW. The DSHA generator set series features PowerCommand[R] digital control system for total system integration, including automatic remote starting/stopping, precise frequency and voltage regulation, alarm and status message display, alternator protection, output metering and auto shutdown-at-fault detection. The generator sets are also NFPA 110 compliant for all standby applications.
According to Tony Satterthwaite, vice president of the Commercial Generator Set Business at Cummins Power Generation, "The pricing of these EPA-certified products will reflect the overall value of our technologies, increased environmental responsibilities, regulatory requirements and rising manufacturing costs. Our goal is to provide value-added technologies that help our customers meet new emissions standards without sacrificing product performance."
