It’s essential that the unit you select for starting turbines and for providing sufficient power for pre-flight checks, also provides the performance and product lifespan that you need. The following checklist has been specifically designed to assist Powervamp customers with their aircraft start unit selection. And of course, Powervamp’s technical support department or appointed distributors will also be pleased to offer advice in helping you select the correct GPU. Is the pack for emergency use only? A GPU with minimum capacity may be sufficient, as it is unlikely to encounter intense usage. ✓Recommended: Powervamp GPU 1700 Will the pack be carried on board? You’ll need to consider the weight of the unit, but beware of reducing weight at the cost of performance. ✓ Recommended: Coolspool 17 Will the GPU be used for programming/pre-flight checks before spool-up? Allow additional amp/hr capacity to ensure a cool start. ✓Recommended: GPU 2400 Will the GPU be used as the main ramp/hangar GPU on multiple operations? It’s best to extend the GPU life with extra amp/hr capacity. ✓Recommended: Coolspool 130 or 260 ramp cart depending on aircraft size (for extended battery life) Is the GPU required for regular compressor washing? The battery will need more frequent replacement if using an undersize pack. ✓ Recommended: Coolspool 260
