Yes, I would like to receive future marketing communications (such as email) from Caterpillar Inc., its affiliates and subsidiaries worldwide and the Caterpillar dealer network. Regardless of whether you decide to receive these marketing communications, Caterpillar will continue to send service/transactional messages, including those that have to do with any accounts that you may have with us.


The Cat® XQ425 provides world class performance and enhanced usability. This model is powered by the fuel-efficient Cat C13 ACERT® engine equipped with the Cat NOx Reduction System. Equipped with the new EMCP 4.4 control panel, the XQ425 features a user-friendly interface and automatic generator set paralleling. A principle advantage of the control system offers simpler and faster voltage changes. Providing greater flexibility when moving between multiple job sites with differing frequency and voltage needs, the auto-configuration capability eliminates the time required when reprogramming units and potential errors. Additional features include lower noise levels and improved part load fuel consumption.
