Caterpillar announces first mid-range Tier 4 Interim certified diesel generator set

December 29, 2010 | By Alyssa Dalton

Caterpillar Inc. has introduced its first mid-range generator set for standby, prime and load management applications, which meets U.S. EPA Tier 4 Interim emissions standards.  

Powered by the Cat C15 engine, the ratings for this 60 Hz package are 500 ekW (Standby) and 455 ekW (Prime). Building on the C15 diesel generator set with ACERT Technology, the C15 Tier 4 Interim certified generator features the EMCP 4 generator set controller and is the first available in the series. Additional product announcements will follow in the coming months.

“An evolution of previous EMCP 3 models, the state-of-the-art EMCP 4 delivers a more intuitive, user-friendly interface/navigation and a scalable platform with added flexibility to precisely match customer power requirements,” reads the company statement.

By using an electronically controlled air management system, the advanced emissions control on the engine acts to lower combustion temperature, achieving decreased nitrogen oxide (NOx) output, it adds. 


The generator set offers an Air-To-Air After Cooler (ATAAC) cooling system, multiple control panel and power connection locations, and enhanced package-mounted circuit breaker options. Additional engine features include an ADEM A4 controller, MEUI fuel system, IP23 protection, a VR6 voltage regulator with load adjustment and 2/3 pitch stator winding.

Headquartered in Illinois, Caterpillar is the manufacturer of construction and mining equipment, diesel and natural gas engines and industrial gas turbines.
