Caterpillar’s Newest Tier 4F Mobile Gen-Set

Caterpillar Inc. has announced an addition to the company’s line of Tier 4 final rental power products with the introduction of the Cat XQ125 mobile diesel generator set. Rated at 125 kVA for prime operation, the new gen-set meets Tier 4 Final emission standards while improving fuel efficiency and optimizing productivity over the previous Tier 4 interim package for rental operations in the United States and Canada.

Equipped with the Cat Connect platform, the new Cat XQ mobile diesel generator allows the dealer to remotely monitor multiple generator set parameters such as run hours and fuel consumption, through analysis tools. The information is expected to allow customers to control costs, improve performance and reduce risks.

The Cat XQ125 also features the EMCP 4.2B control panel providing power metering and protective relaying along with engine and generator control and monitoring. The EMCP 4.2B is embedded with programmable logic controller (PLC) functionality, which enables the generator set to monitor and control other equipment within the operation.  Each EMCP4.2B includes inputs to collect supplementary data for the PLC to process when operating the generator set and activating external equipment. On a remote location without the ability to supply power to the battery charger, the PLC would likewise monitor the battery voltage to start and stop the machine to preserve the battery.

The Cat XQ125 is powered by a C 4.4 ACERT industrial diesel engine. Further, the gen-set has what Cat calls “rental-ready” construction that allows for transportation around project sites, while a galvanized enclosure protects the XQ125 from potentially harsh environments.  The XQ125 is further capable of 500-hour oil change intervals.
