Hydraulics International, Inc. (HII) designs and manufactures Aircraft Ground Power Unit, 60KVA GPU & 90 KVA GPU diesel generated AC 400HZ and 28 VDC power units built for rugged military demand and environment with high performance. The system configuration is based on the most reliable and suitable state-of- the-art control and monitor technology with ease of operation and diagnostics in mind. The system is easy to operate, intuitive with an interactive data display and requires very low maintenance.  The HII GPU provides the user with required maintenance power, automated built-in and diagnostic test features. The Cummins QSB 4.5, 155 HP, Tier III engine is quiet and efficient combined with a 400HZ generator with superior regulation.


  • Low emission by using a diesel engine that meets the EPA TIER III requirements
  • Multi-fuel engine operates with all DF-1, DF-2,JP-4, JP- 5 and JP-8
    • Low profile and narrow structure provides better air transportability, can be forklifted or sling loaded
    • Heat exchanger and cooling system for the engine and electrical/electronic system is designed for high ambient temperature
    • Low noise emission
    • Large stainless steel fuel tank for long hours of operation
      • Lift-off doors all around the unit provide full and easy access for inspection and maintenance.
      • AC generator is brushless synchronous type alternating current and is equipped with an automatic solid state voltage regulator
      • Superior frequency regulation via electronic controlled engine governor system
      • This GPU incorporates a state-of-the-art computer technology to provide friendly user interface control, monitoring and diagnostic.
