Overview

In addition to improved fuel efficiency, the next generation XQ1475G rental generator provides significant power density advantages. Caterpillar developed new exhaust stacks that reduce spacing requirements for sites requiring multiple units. This allows for an increase of 47 percent on-site power density over the previous capabilities.
