It is designed for regional DC aircraft operators and FBOs requiring continuous ripple-free power in the hangar and remote power for line operations and turbine starting on the ramp. No other GPU delivers the versatility and convenience of Powervamp’s Coolspool Hybrid 300. This compact and efficient diesel GPU provides continuous DC power and an auxiliary AC single phase output. Very high DC amperage from its ultra-high-discharge batteries is available instantly for turbine starts and short-term loads that may exceed the generator’s continuous output. The Coolspool Hybrid 300 was originally developed in 1995 for the UK military as a low cost self-contained GPU designed to supply continuous DC power all day for pre-flight/avionics and random turbine starting. The latest generation Coolspool Hybrid 300 delivers up to 300A continuously at 28V, either from the diesel generator or by connecting the GPU to a 3-phase mains supply, thereby allowing it to be used in confined spaces. A selector switch allows the user to select Generator or Mains mode, enabling the GPU to provide power from the Generator or the Mains input. In enclosed spaces such as maintenance shops or hangars, with the diesel engine shut down and the unit connected to a mains supply, the Coolspool Hybrid 300 while providing 28V, will automatically recharge its integral batteries. Available In various configurations and in series production over 17 years, with sales to several armed forces, the latest Coolspool Hybrid 300 is the civil version for FBOs, regional airlines, and operators requiring versatile remote power at a fraction of the cost of a conventional diesel GPU.
