Powervamp’s 28 volt DC Coolspool ramp carts are designed to replace diesel GPUs or TRUs.
Operating at a fraction of the cost of a diesel GPU, yet able to deliver the same power and turbine starting output. Powervamp’s large 28 volt Coolspool battery cart GPUs are increasingly being used to provide 28 volt DC power required for pre-flight checks, avionics maintenance. They are ideal for crew training, aircraft turnround/cabin cleaning at remote airport stands or where noise curfews or the lack of any electrical supply prohibit any other method of powering the aircraft’s DC systems.
These 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.
