cat article

For industrial jobsites or residential areas where noise level is a concern, there is no better system.

The VMAC Multifunction Power System, powered by a Cat® Industrial Diesel Tier 4F engine, includes six power sources in one compact, quiet system. With noise reduction panels, low and high idle controls and Standby Mode, operators can safely communicate while working without disturbing the jobsite or the neighbors. This self-contained system can be fully integrated into any diesel work truck fuel system or skid-mounted for stand-alone applications with an optional external fuel tank.

Benefits

SIX POWER SOURCES, ONE QUIET MACHINE
For industrial jobsites or residential areas where noise level is a concern, there is no better system. The VMAC Multifunction Power System, powered by a Cat® Industrial Diesel Tier 4F Engine, includes everything needed for safe operations on any jobsite in a single compact system. Components include: air compressor, generator, welder, booster/charger, PTO with optional hydraulic pump, and cold climate kit. With noise reduction panels, low and high idle controls and Standby Mode, operators can safely communicate while working without disturbing the jobsite or the neighbors.

EASY OPERATION & SWITCHING BETWEEN SYSTEMS
The VMAC Multifunction Power System allows operators to seamlessly switch between operations, without the hassle of complicated controls or maneuvering multiple machines on the jobsite. This means more time working, improving productivity and getting customers back to work faster. It is designed for ease of use, to run efficiently with only one operator.

SAVE TRUCK MAINTENANCE & FUEL COSTS
The VMAC Multifunction Power System reduces truck maintenance and improves fuel economy by allowing operators to turn their truck engine off while on the jobsite. Also, by reducing vehicle weight by up to 140 lb, automatically idling the Cat® engine up/down with air demand and turning the Cat® engine off/on with air demand, the VMAC Multifunction Power System allows operators to carry more tools or equipment or improve fuel economy.
