Producing reliable power from 550 kVA to 715 kVA at 50 Hz, our C18 diesel generator sets are made to meet your standby and prime applications. Each is designed to ISO 8528-5 transient response requirements and built accept 100 percent rated load in one step. Our C18 generator sets range from low fuel consumption systems to EPA Stationary Emergency (Tier 2) certified. Seismic certification is also available for select models, so you can deliver power despite disturbances. Our integrated control system, including ATS and switchgear ensure a consistent power supply and connection to your fleet through on-site and remote monitoring options. We offer a wide range of EMCP 4 control panel options, with a simple screen display, consolidating all your management and diagnostics tools. The EMCP 4.4 controller provides on package paralleling capability, allowing you to use multiple generator sets to power your facility, providing added capacity and redundancy. We've made our generator sets adaptable to your demands with a broad range of accessories and bolt-on system expansion attachments. Find flexible packaging to fit your spatial restrictions and environmental conditions. Even choose UL 2200 and CSA certified package options for added safety.
