Cummins Large Gen-Sets Tier 4 Final Certified

Posted on April 23, 2014

Cummins Power Generation announced that it has received Tier 4 final certification from the Environmental Protection Agency (EPA) for its line of high-horsepower diesel generator sets from 680 kW to 2750 kW. The certification comes eight months ahead of the implementation deadline of Jan. 1, 2015.

“We are proud to be the first company to be awarded Tier 4 final certification for our generators,” said Dennis Heathfield, executive director, Power Systems, Cummins Power Generation. “This achievement definitively demonstrates Cummins’ leadership role in diesel emissions reduction technology. By achieving this emission reduction, we are providing customers with more fuel-efficient and cleaner generators.”

The new Tier 4 final gen-sets achieve a 99% reduction in particulate matter (PM) emissions when compared to a Tier 2 product, Cummins said. Similarly, through  the use of selective catalytic reduction (SCR) aftertreatment, nitrogen oxide (NOx) emissions have been reduced 94%, the company said.

Tier 4 final-certified units are especially relevant, Cummins said, in applications where on-site power is used for purposes other than standby emergency power, such as peak shaving, storm avoidance, rate curtailment and prime power. Without Tier 4 Final certification, the EPA severely limits these non-emergency uses, the company said.

The newly certified units will also qualify for standby power applications in locations where air quality is impaired or where stricter local air quality regulations require Tier 4 Final generator sets even for emergency use, Cummins said.
