CAT XQ425T4F DIESEL GENERATOR 772 hOURS
The Cat® XQ425T4F WITH 772 HOURS UNDER WARRANTY provides world class performance and enhanced usability. This model is powered by the fuel-efficient Cat C13 Tier 4 Final engine compliant 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.
