C27 (60 Hz)

C27 (60 Hz)

The C27 diesel generator sets have been developed for your mission critical, standby and prime applications. Producing reliable power from 680 to 800 ekW at 60 Hz, each generator set has been designed to meet ISO 8528-5 transient response requirements and to take on 100 % rated load in one step. The C27 is certified as a low fuel consumption system as well as having a certificate for EPA Stationary Emergency (Tier 2). Seismic certification is also available for selected models, ensuring your generator sets are equipped for that unexpected disturbance. The integrated control system, including 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. It's not just quality that matters but customization, choose from a broad range of accessories and bolt-on system expansion attachments. Discover our upgradeable packaging options to work with your spatial restrictions and environmental conditions. Our C27 generator sets are developed for such prerequisites, so that you can meet your specific power needs. Build in additional safety features with the UL 2200 and CSA certified package options.
