New Caterpillar Power Module

Posted on May 21, 2013

Caterpillar has introduced its next generation portable power module targeted primarily toward rental applications. The Cat XQ2000 Power Module is available in ratings of 1640 kW at 60Hz and 1400 kW at 50Hz in continuous duty applications.

Cat said the new power module is designed to combine high durability and reliability with strong fuel economy derived from the broad use of the company’s own components. The unit is driven by a Cat 3516B diesel engine and incorporates a variable frequency drive and high efficiency fan that Cat said improves mechanical efficiency. The fan draws 40% less load on the engine at 100% generator load, which results in a fuel economy improvement as high as 8% over the previous generation, the company said.

In addition to improved fuel efficiency, the next generation XQ2000 is engineered to provide significant power density advantages. Caterpillar developed new exhaust stacks that reduce spacing requirements for sites requiring multiple units, which the company said allows for an increase of 47% on-site power density over previous capabilities. With a target of less than 4°C (8°F) temperature rise across the site, the new layout design allows a 1.53 kW per sq. ft. power density at the continuous rating at 60 Hz, and 1.34 kW per sq. ft. at 50 Hz.
