COOLSPOOL 17 The Coolspool 17 is used extensively on light/medium turbine helicopters or aircraft and all 24V DC piston diesel/Avgas engines. When connected in parallel with Powervamp’s PS30M DC power supply, both units deliver a unique lightweight combination of performance and versatility. COOLSPOOL 29 AND COOLSPOOL 29 TWIN The Coolspool 29 is designed for larger twin turbine aircraft and helicopters where additional amp/hour capacity is required to maintain voltage under load. When compared with 24V DC start units of the same capacity, these units deliver significantly higher performance, resulting in faster spool-ups and cooler starts impacting directly on turbine life. The units are designed to be carried on board for emergency power or turbine starting and are each fitted with an automatic 3-stage internal charger for maximum cell longevity.
