Coolspool 29 Twin 28V Aircraft Start Unit

upon request

Size and weight are important considerations for hand-portable aircraft start units. Situations exist where additional battery capacity and performance is required while retaining the essential benefits of mobility or ‘hand-portability’. When compared to a 24V DC start unit of the same capacity, the Coolspool 29 delivers a significantly higher performance, resulting in faster spool-ups and cooler starts impacting directly on turbine life. The Coolspool 29 Twin can be split into separate modules for ease of transport and is designed to be carried on board for emergency power or turbine starting. This aircraft start unit is fitted with an automatic 3-stage internal charger for maximum cell longevity and is suitable for starting larger turbine aircraft and helicopters. Each Coolspool 29 is fitted with solid state voltmeter with ‘push to view’ button to monitor battery voltage. A spring-loaded output cover ensures the aircraft start unit is cleared for air transportation. Supplied with NATO lead set, charge lead and heavy-duty canvas protective jacket.
