We’re Tier 4 Final Certified

Only Cummins Power Generation has a wide range of EPA Tier 4F-certified stationary generator sets (gensets) to provide critical protection in virtually any standby power application. With power nodes ranging from 750 to 2,750 kW, Cummins gensets offer the highest possible emissions reductions. As a result, our large gensets afford you total operational flexibility for standby power applications, whether you require emergency backup assurance or choose to operate in non-emergency scenarios.

Standby Power Has Never Been So Clean

A leader in emissions reduction, Cummins has pioneered a number of engine and aftertreatment technologies that meet and exceed the EPA’s Tier 4F emissions standards. For generator sets of 750 kW and greater, we developed selective catalytic reduction (SCR) technology using diesel emissions fluid (DEF) to achieve the power industry’s most complete line of EPA-certified Tier 4F high-horsepower gensets.

Stationary generator sets operated in regions governed by a local environmental review board (ERB) may be subject to even stricter emissions regulations. Many of these areas, known as non-attainment zones, have enacted clean air requirements that adhere to the EPA’s Tier 4F standard, effective in 2015. For these stringent applications, Cummins provides Tier 4F certified gensets that reduce the exhaust constituents to the industry’s lowest emissions standard.

Tier 4i or 4F Certification Enables Unlimited Non-Emergency Use

As of January 1, 2011, any new installation of a standby stationary genset must be EPA-certified for Tier 4i standards. In 2015, the EPA’s Tier 4 Final standard will come into effect, essentially reducing emissions limits to the minimum of the EPA’s proposed reductions. Unlike Tier 2 certification, which allows for only emergency standby power use, the Tier 4 standards enable genset owners to operate as they see fit for multiple non-emergency purposes.
