C9 Generator Set

Producing reliable power from 180 ekW to 300 ekW at 60 Hz, our C9 diesel generator sets are made to meet your standby and prime applications. Each is designed to meet ISO 8528-5 transient response requirements and accept 100 percent rated load in one step. All C9 generator sets are engineered to EPA Stationary Emergency (Tier 3) emissions standards — it's how we're helping protect and power the world you live in. Seismic certification is also available to maintain power during unexpected disturbances. Our integrated control system, including ATS and switchgear, ensures a consistent power supply and connection to your fleet through on-site and remote monitoring options. The EMCP 4 control panel, with a user-friendly interface, puts our management and diagnostic tools in one. We offer a wide range of accessories and bolt-on system expansion attachments so you can adapt your generator sets to your needs. Find flexible packaging options to work with your spatial requirements and environmental conditions. Even select from UL 2200 and CSA certified package options for added safety. Tailor your C9 generator sets to take on today's power needs — and tomorrow's.
