Land Electric-Drive Modules

Oil and gas producers have relied on Caterpillar since the industry's earliest days. For 60 years, we've powered the petroleum business on land. Now we go with it onto the ocean, hundred of miles out, thousands of feet down.

3512C (HD) Land Electric-Drive Drilling Module

Oil and gas drilling is a complex task that requires specialized power generation equipment. Cat 3500 generator sets are specifically designed for drilling operations of electric AC rigs. They combine decades of field experience of the 3500 platform with the latest electronics to ensure highest performance, low emissions, and simplified operator interface. 3512C (HD) land drilling generator set. Ratings: 1245 ekW (1780 kVA) @ 60 Hz (1200 rpm). Meets U.S. EPA Tier 2 equivalent emission standards. Available using U.S. EPA Flexibility and for other regulated and non-regulated areas.
