Man-portable Generators

The current situation and challenge

XRDi faces two principal challenges in man-portable generators.

  • Military

    • More theater-based electronics has increased demand for electrical power.
    • Man-portable generators meet this need, need to operate on “the fuel of opportunity” (ie whatever is available), and also meet the military’s One Fuel Forward policy

  • Disaster and Emergency

    • The need to airlift and carry generators to disaster zones creates new demand for smaller, lighter weight, more efficient generator units.
    • Logistics, costs of transport and going the “last mile” means that the lighter, higher power units bring exponential benefits.
    • Fuel is generally scarce in disaster zones, generators that operate on whatever fuel is available provide significant advantage to both responders and survivors.

The XRDi solution

  • XRDi and its proprietary technology are known in the industry and the company has traditionally been recognized as a leader in small engine design
  • Our engine solutions operate on whatever fuel is available, offer significant power/weight/volume ratio advantage, low emissions, and are based on simple, easy to service technology.
