C18 (60 Hz)

Select Units

Overview

The C18 diesel generator sets have been developed for your mission critical, standby and prime applications. Producing reliable power from 500 to 750 ekW at 60 Hz, each generator set has been designed to meet ISO 8528-5 transient response requirements and built to 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 optional EMCP 4.4 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 C18 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.
