Overview

Producing reliable power from 635 ekW to 800 ekW at 60Hz, our C27 ACERT® diesel generator sets are made for your mission critical, standby and prime applications. And we've engineered each to ISO 8528-5 transient response requirements and to take on 100 percent rated load in one step.C27 generator sets are available from low fuel consumption systems to EPA Tier 4 Interim certification. Seismic certification is also available for select models, so your generator sets are equipped for unexpected disturbances. Our integrated control system, including Cat® UPS, ATS and switchgear, ensures a consistent power supply and connection to your fleet through on-site and remote monitoring options. Our EMCP 4 control panel features a user-friendly interface and puts your management and diagnostics tools in one location. The EMCP 4.4 controller provides multi generator set paralleling capability, allowing you to use multiple generator sets for increased power output and improved reliability. We offer a broad range of accessories and bolt-on system expansion attachments to meet your power needs. Find flexible packaging options to work with your spatial restrictions and environmental conditions. Build in additional safety features with UL 2200 and CSA certified package options.
