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 4 emissions standards. For generator sets of 1,000 kW and greater, we developed selective catalytic reduction (SCR) technology using diesel exhaust fluid (DEF) to achieve the power industry’s most complete line of EPA-certified Tier 4 high-horsepower gensets.

Stationary generator sets operated in regions governed by a local environmental review board 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 4 standard, effective in 2015. For these stringent applications, Cummins provides Tier 4 certified gensets that reduce the exhaust constituents to the industry’s lowest emissions standard.

Certification Enables Unlimited Non-Emergency Use

As of January 1, 2015, any new installation of a stationary generator set intended for use in non-emergency operation must be EPA-certified for Tier 4 standards. Unlike products certified only to the stationary emergency emissions levels, which allows for only emergency standby power use, the Tier 4 standards enable genset owners to operate as they see fit for any non-emergency purpose.
