RIVVAL's 28 volt DC Coolspool 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, new
generation, 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 footprint are important environmental considerations.
With the price of diesel increasing and stricter legislation on noise and
CO2 emissions, the advanced technology Coolspool battery cart
range is the way forward for regional and feeder airlines’ FBOs and
ground handling agents under pressure to reduce direct operating
costs.
RIVVAL’s large 28 volt Coolspool battery cart GPUs are
increasingly being used to provide the smooth 28 volt DC power
required for pre-flight checks, avionics programming or maintenance.
They are ideal for crew training, aircraft turnround/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, Coolspool 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 dollars
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 Coolspool show
savings enabling many operators to amortise the Coolspool GPU in
less than 6 months while benefiting from the favourable 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
the minimum of technical knowledge, Coolspool GPUs are easy to
operate and repair.
The Coolspool battery cart range is perfect for remote operations,
ramp/hangar duty or regular line operations. Unlike diesel GPUs which
need regular maintenance, the Coolspool 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
Coolspool carts, RIVVAL 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.
