Caterpillar introduces C175-16 U.S. EPA Tier 4 Interim-certified diesel generator set
This 60 Hz package — rated at 3000 to 3100 ekW for standby and mission-critical power, 2725 to 2825 ekW at prime power and 2500 to 2600 ekW at continuous power — offers fuel efficiency and lower emissions in a compact footprint.
With the addition of the C175-16, Caterpillar offers the widest range of Tier 4 Interim-certified generator sets in the industry, ranging from 455 kW to 3100 kW.
The C175-16 generator set meets EPA Tier 4 Interim emission standards with the Cat clean emissions module (CEM). This aftertreatment system features a diesel oxidation catalyst (DOC) combined with a selective catalytic reduction (SCR) module and an air-assisted urea 
injection system to reduce oxides of nitrogen (NOx), hydrocarbons and particulate matter.
Cat Tier 4 Interim generators can be integrated into larger power systems that include the complete line of Cat power equipment, such as line interactive flywheel UPS, double conversion battery UPS, paralleling switchgear and automatic transfer switch products.
“Caterpillar was the first manufacturer of Tier 4 Interim-certified generator sets rated for more than 1 MW,” said Robert Koval, Investor Projects General Manager of Caterpillar Electric Power Division. “For our U.S. customers that require generators to operate outside of a stationary emergency application, we have EPA-certified solutions."
(Tier 4 is the EPA standard for non-road engines).
