The EPA’s Tier 4 regulations are frequently a source of confusion for those who rely on large stationary generators for backup and prime power uses. Owners and operators of these generator sets (gensets) have many questions about the EPA’s emission standards and what the implications mean to them. What’s the difference between Tier 4i-certified versus compliant? Do I need a Tier 4i or Tier 4F-certified or 4F-capable generator set? What are the acceptable run times for emergency versus non-emergency use? How can I meet the stricter requirements of local restrictions and non-attainment zones, and how does this differ from national emissions standards?
Cummins Power Generation has the answers.
At Cummins, we know the complexity of these EPA Tier 4 regulatory issues can be difficult to comprehend. That’s why we’ve taken a leadership role on emissions from the beginning. We work closely with the EPA to fully understand every subsequent change to their regulations as they implement ever cleaner air standards. Cummins was the first manufacturer to introduce EPA Tier 2 and Tier 3 generators to the market, well ahead of the regulatory deadline. Our commitment to providing you with total operational flexibility in how you choose to use generator power is what drives us to stay ahead of the game.
We were the first manufacturer to offer a full range of Tier 4i-certified gensets, and the first to receive Tier 4F certification when the EPA began issuing certificates in January 2014.
