Product Information

Product Information

The Coolspool 410 28V DC battery cart is designed for use on DC regional jets (ERJs) and DC turboprop aircraft in scheduled airline services. Using maintenance-free ultra- high-discharge TPVRLA (thin plate valve regulated lead acid) batteries, the Coolspool 410 delivers the combination of instant high amps for starting with the key feature of guaranteed pure DC waveform, essential for the highly sensitive electronics on some modern DC aircraft.

The Coolspool 410 battery cart has proved itself as a directreplacement for diesel ground power at the ramp. Operating at a fraction of the cost of a diesel GPU, the Coolspool 410 delivers huge cost savings for airlines. Its zero carbon footprint and noiseless operation also benefit operators with its environmental and marketing advantages, while its total silence significantly improves the working conditions of ramp personnel through the absence of fatiguing noise.

Proven over many years of service since their first introduction more than 12 years ago, the large Coolspool carts are rapidly gaining in popularity as regional airlines in the Caribbean, Pacific, South America, the UK and Europe expand their turboprop fleets and seek ways to reduce operating costs. With its low initial capital investment and very low operating costs, the Coolspool 410 has proved to be the perfect GPU where new destinations or infrequent services demand cautious investment.

The simplicity of operation and lack of maintenance makes the Coolspool 410 ideal for use at smaller airports, where gate agents or airline personnel often perform multiple tasks; while at major hubs, a regional airline with multiple departures using the Coolspool 410 as the source of its ground power can expect to experience huge maintenance and fuel savings.

In a series of on-going acceptance trials with various aircraft operators, one of which is shown here at a recent trial in Marseille, France, Powervamp's latest design of compact 28 volt DC battery cart the Coolspool 410, is seen powering the ATR72 aircraft and starting both engines. You will hear the initial turbine spool up under the huge power delivered by Powervamp Coolspool 410 GPU as the starter turns the turbine. As fuel is introduced into the starboard engine the turbine rapidly spools up and becomes self-sustaining. At this stage you will see that the propeller is not turning. This is because the ATR 72 features a "Hotel power Mode" wherein the propeller can be braked with the turbine running at ground idle . This allows the Starboard main turbine to provide the power to all the aircraft systems via the normal starter /generator without the aircraft requiring a separate APU (auxiliary power unit).

This feature allows the aircraft to park at the ramp with personnel operating around the aircraft without the unacceptable danger of a rotating propeller. Once cleared for departure and pushed back, the crew will normally cross start the Port engine, whereupon the propeller brake is released on the starboard engine. What is shown is a simulated ramp operation with lengthy pre-flight checks and a double start with prop brake release and both propellers turning and amps and volts measured in the final successful test of the day.
