Powervamp coolspool Hybrid 300
The Powervamp Coolspool Hybrid 300 ground power unit is designed to provide continuous power for avionics and to start the engines on all DC turbine and turboprop aircraft by using its fully Tier IV compliant 3-cylinder, water-cooled Kubota diesel engine.

Coolspool users benefit from a compact unit, user friendly all weather controls and very low operating costs, with the further advantage of low dBA signature and reduced CO2 emissions. Its quite normal for a diesel ground power unit (GPU) four times the size of the Coolspool Hybrid 300 to deliver the same peak amperage for starting large turbines.

The Coolspool Hybrid 300 achieves the same starting performance using a 900cc (55 cu In) Kubota diesel engine coupled to a powerful generator powering 3 x 100amp 28V DC power supplies.

These operate in parallel with a bank of high discharge batteries that provide instant ripple free power for turbine starting and aircraft loads exceeding 300 amps.

The Coolspool Hybrid 300 is suitable for all types of operation, including offshore helicopter operations, FBO and maintenance organisations as well as daily regional airline use.

Bond Offshore, based at Humberside Airport, have been long time users of the Coolspool Hybrid 300 and rely on it start the twin turbines of their Agusta Westland AW13 to facilitate flights to oil platforms in the Southern North Sea. The Hybrid is also used dailey  further 4-6 times to start turbines on various other helicopters

Other customers may require multiple departures of large regional aircraft, (such as Q400, ATR 42 / 72, ERJ 135 /145, Jetstream 32 /42 and Saab 340 operators). and its in these situations that the Coolspool Hybrid 300 can be fitted with Powervamp’s ‘PBS’ (Power Boost System).

The PBS sustains voltage during the critical initial start sequence on large turboprop aircraft with shaft or free turbine engines, thereby ensuring a fast, cool start while maximising battery life.No other GPU delivers the versatility and convenience of Powervamp’s Coolspool Hybrid 300.   This compact and efficient diesel GPU also provides single phase AC output to enable ground staff to operate vacuum cleaners or other equipment during night servicing.

The Coolspool Hybrid 300 guarantees clean power and delivers the versatility and essential reliability that operators demand, at a fraction of the cost per turnaround and with minimum environmental impact compared to a conventional diesel ground power unit.

For hangar use, or use within a confined space, the Coolspool Hybrid 300 engine can be shut down and by operating a dedicated selector switch, the generator can be isolated to allow external 3-phase AC power to be connected from a suitable utility supply.

The Hybrid can now be operated within environments where a diesel GPU would not normally be allowed to and the full output is available with the external power source constantly maintaining the batteries in a full state of charge.

Available in various configurations and in series production over 17 years, with sales to several armed forces, the Coolspool Hybrid 300 is the civil version of Powervamp’s DC GPU. It is designed for operators requiring versatile, standalone, high output DC power at a fraction of the cost of a conventional diesel GPU.
