FW28 ramp carts are designed to replace diesel GPUs or fixed and semi-mobile transformer rectifier units (TRUs).
Where no mains power is present or noise curfews prohibit use of diesel GPUs, they are a highly efficient, low cost power source - operating at a fraction of the cost of a diesel GPU, yet able to deliver the same power and turbine starting output. These large, powerful, heavy-duty battery carts provide a combination of instant high amperage with pure DC wave form and full mobility, low initial investment and extremely low operating costs. Their zero noise and zero carbon footprints are important environmental considerations. With the price of diesel increasing and stricter legislation on noise and CO2 emissions, the advanced technology FWP battery cart range is the way forward for regional and feeder airline's FBOs and ground handling agents under pressure to reduce direct operating costs.
FWP large 26-28 V battery cart GPUs are increasingly being used to provide the smooth 26-28 V DC power required for pre-flight checks, avionics programming or maintenance. They are ideal for crew training, aircraft turnaround/cabin cleaning at remote airport stands (where power can be required for anything from a few minutes to several hours) or where noise curfews or the lack of any electrical supply prohibit any other method of powering the aircraft's DC systems.
Unlike a diesel GPU, FWP battery carts are simply connected to a charger at the end of the day. Annual savings in fuel and maintenance are typically between $40,000 and $300,000 compared with a diesel GPU running daily. There are no diesel costs, no exhaust, no noise, no pollution - and no maintenance.
Direct cost comparisons between a diesel GPU and a FWP cart show savings enabling many operators to amortize the FWP GPU in less than 6 months while benefitting from the favorable public and corporate publicity of using environment-friendly equipment.
The modular design of the advanced technology battery pack allows rapid swap-out if necessary. Batteries are sealed, maintenance-free and cleared for air transportation. Able to be used by personnel with minimum technical knowledge, FWP GPUs are easy to operate and repair.
The FWP battery cart range is perfect for remote operations, ramp/hangar duty or regular line operations. Unlike diesel GPUs which need regular maintenance, the FWP carts need only a single or 3-phase mains connection for their charger - depending on charge time.
For operators with multiple DC aircraft movements requiring several carts, Flywell Power supplies a remote multi-charge station which allows several battery carts to be simultaneously re-charged. Because the special cells have no memory effect, carts not in use can be recharged at any time.
