Diesel Generator Sets

Cat C18 Generator Set

Minimum Rating 455 ekW

Maximum Rating 500 ekW

Emissions/Fuel Strategy U.S. EPA Tier 4 Final

Producing reliable power from 455 ekW to 600 ekW at 60 Hz, our C18 diesel generator sets are made to meet your standby and prime applications. The engines are certified to the US EPA Tier 4 Final emissions levels. Each is designed to meet ISO 8528-5 transient response requirements and built to accept 100 percent rated load in one step. Seismic certification is also available for these 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.

  • The Tier 4 Final engine has been optimized to work with the Cat CEM.
  • The CEM is a reliable, compact, and lightweight system that gives maximum installation flexibility.
  • It features a diesel oxidation catalyst for particulate matter (PM) and hydrocarbon (HC) control.
  • Selective catalytic reduction (SCR) reduces NOx output and provides integrated sound attenuation.
  • The CEM is controlled by a separate dosing module that has been integrated into the standard generator set controls for complete monitoring, protection and closed loop NOx control.
  • For more information on the CEM, refer to cut sheet LEHE0359.
