Wherever you need an independent external power source, the ITW GSE 4400 ground power unit can do the job. The 4400 unit is a mobile, diesel-powered 400 Hz unit available with Cummins Tier 3 or Tier 4 engine, so no matter where in the world you are located, we can match your power requirements.
The 4400 engine drive GPU provides a quiet, fuel-efficient apron power system. It is easy to move around, remarkably tough and supremely reliable.
The low-profile design, mounted on a towable trailer with fifth-wheel steering, makes this ultra-reliable engine-driven 400 Hz GPU easy to maneuver around the congested apron areas of modern airports. Due to the low weight of the GPU, you can tow it around even with small towing equipment thus reducing the total cost of ownership.
The low fuel consumption of the ITW GSE 4400 family results in big savings on your fuel costs as well as reducing harmful engine emissions.
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.
Major components such as the canopy and cable trays are manufactured from fully recyclable polyethylene, which is unique in the ground power industry. Unlike other commonly used materials, polyethylene components can be easily recycled and reused, minimizing both environmental impact and end of life disposal costs.
As one of the most advanced GPUs in the market, the 4400 is available in a dual voltage AC/DC version. This combo unit is capable of delivering 400 Hz and regulated 28.5 VDC power, simultaneously and independently. The 28.5 V Active Rectifier Unit (ARU) - available as a standard option - delivers superior voltage quality at the aircraft plug without jeopardising the 400 Hz voltage. It goes without saying that the ITW GSE 4400 will power your aircraft, whether it is a narrow body or a turbo prop.
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 trouble-shooting.
