Overview

The Cat® C1.1 Industrial Power Unit is offered in ratings ranging from 14.4-18.4 bkW/19.3-24.7 bhp @ 2200-2800 rpm. These ratings meet U.S. EPA Tier 4 Final emission standards. Ratings: 17.3-18.1 bkW (23.2-24.3 bhp) @ 2800-3000 rpm are available for Europe and, depending on applicable emission standards, may be introduced in other regulated areas. Nonroad engines less than 19 kW (25 hp) are not currently subject to EU emission standards. Conveniently pre-configured for a wide range of applications, the Cat® Industrial Power Unit is a complete power package containing a radiator, flywheel, alternator and alternator wiring completely pre-assembled for fast, straightforward installation in a number of OEM, customer and packager applications. These fuel efficient units are ready made for irrigation, industrial, mining and other pump applications.
