US Environmental Protection Agency (EPA) has given Cummins’s new line of diesel backup power gensets a Tier 4 Final certification.
EPA approved the complete line of high-horsepower gensets, ranging from 680kW to 2750kW. The generators are mainly used for backup power in critical power applications such as hospitals and data centres. The line is also designed for standby power applications where air quality is impaired and for emergency use.
Cummins said it is the first manufacturer receiving a Tier 4 Final certification. “We are proud to be the first company to be awarded Tier 4 Final certification for our generators,” said Dennis Heathfield, executive director at Cummins.
The Tier 4 Final generators achieve a 99% reduction in particulate matter emissions in comparison to Tier 2 products. “By achieving this emission reduction, we are providing customers with more fuel-efficient and cleaner generators,” added Heathfield.
EPA adopted Tier 4 emission standards in 2004 for new off-road diesel engines in order to reduce hydrocarbons, carbon monoxide, particulate matter and nitrogen oxide. Tier 4 Final standards require a reduction to near-zero levels.
