  • Reliable ITW GSE AC generator
  • Low noise design
  • Superior voltage regulation

Icon Based User Interface

The clear, icon-based user interface, shown on a high-res color screen is easy to operate and helps ensure correct operation. The display can be customized to suit most language requirements. Technicians can also use the control interface for monitoring operating data, maintenance, and practical troubleshooting.

Easy Access to the Inside of Unit

The engine, alternator, controls, batteries, and cables are all easily accessible but completely protected under a tough, corrosion-free canopy made of resilient medium-density Polyethylene. All maintenance points that need to be checked regularly (fuel, oil, water, etc.) are easy to access. The entire canopy can be removed by hand in less than two minutes – no hoists or cranes needed.


  • Variable-speed engine gives a lower operating noise level especially during low load situation
  • Engine RPM is not tied to output frequency as in case of a diesel unit
  • Longer life expectancy can be achieved as compared to fixed speed engine
  • Able to regulate the speed of the engine to provide just the required capacity to meet the load
  • Less noisy working environment for operators
  • Higher return on investment for the equipment owner


  • Tier 4: Cummins QSF2.8 diesel engine operating between 1600 and 2400 RPM. EU stage 3B compliant
  • Turbocharged 4-stroke, inline 4 cylinders common rail fuel system
