Cat® C18 Diesel Generator Set Expands Caterpillar’s Industry-Leading Lineup of Power Solutions Offering High Power Density

For Worldwide Release: June 9, 2020 
Release Number: EEPR0720

DEERFIELD, IL – Caterpillar Inc. announced the launch of three new power nodes for the Cat® C18 diesel generator set that offer higher power density, occupying up to 55% less floor space than a leading competitive product offering the same power outputs.

Available now, the new Cat C18 diesel generator set features three 60-Hz power nodes offering standby ratings from 650 kW to 750 kW and prime power ratings from 600 kW to 680 kW. It is designed for applications requiring certification to U.S. EPA Tier 2 emission standards, and an enclosure is available for applications requiring noise attenuation or protection from the elements.

“Standby power is a considerable investment for most smaller enterprises, so it’s critical to select an efficient, accurately sized solution that fits in the most compact space possible,” said Jason Kaiser, general manager for Caterpillar Retail Electric Power Solutions. “Caterpillar’s new generator sets with high power densities allow customers to get power when they need it most while substantially reducing upfront costs for site preparation, transportation, and installation.”

The Cat C18 diesel generator set with high power density is designed to meet the NFPA power restoration requirement for Level 1 systems and accept 100 percent block load in one step. It meets ISO 8528-5 requirements for steady state and load acceptance.

The Cat C18 generator set utilizes the field-proven Cat ADEM™ A4 engine control module (ECM). This module seamlessly integrates all engine functions including ignition, governing, and air-fuel ratio control for optimal performance while protecting the engine.

Caterpillar delivers innovative power systems engineered for durability, reliability, and value. The company offers worldwide product support, with parts and service available globally through the Cat authorized service and dealer network. In addition, dealer technicians are trained to service every aspect of Cat equipment.
