Producing reliable power from 36 ekW to 90 ekW at 60Hz, our C4.4 ACERT™ diesel generator sets are engineered to meet your standby and prime applications, and measure up to your power standards. All are tested to maximum load before they leave any one of our ISO 9001 certified facilities. And because we believe power is more than quantity of kilowatts but quality of performance, we’ve incorporated our common rail fuel system for improved fuel efficiency, designed to meet EPA Stationary Emergency (Tier 3) emissions standards. Seismic certification is also available to maintain power during unexpected disturbances. Our integrated control system, including Cat® UPS, ATS and switchgear, ensures a consistent power supply and connection to your fleet through on-site and remote monitoring options. The EMCP 4.2 control panel, with a user-friendly interface, puts our advanced management and diagnostic tools in one. No two power needs are alike, which is why we offer a broad range of accessories and bolt-on system expansion attachments. Find flexible packaging options to work with your spatial and environmental conditions. It’s already built to exceed your expectations — customize your C4.4 generator sets to meet your demands.
