Product Information

Product Information

The Coolspool 17 is available in two nominal output voltages, 26V DC or 28V DC. This aircraft start unit is used extensively on light/medium turbine helicopters or aircraft and all 24V DC piston diesel/Avgas engines. Upper Fadec limits vary according to the manufacturer’s software and for this reason two versions of the Coolspool 17 are available.

When compared to a 24V DC start unit of the same capacity, the Coolspool 17 delivers a significantly higher performance, resulting in faster spool-ups and cooler starts impacting directly on turbine life. This aircraft start unit is designed to be carried on board for emergency power or turbine starting and is fitted with an automatic 3-stage internal charger for maximum cell longevity.

The Coolspool 17 is fitted with solid state voltmeter with ‘push to view’ button to monitor battery voltage. Securing the output flap of the padded jacket ensures the aircraft start unit is cleared for air transportation.

Supplied with Nato lead set, charge lead and heavy-duty canvas protective jacket. When connected in parallel with Powervamp’s PS30 DC power supply, both units deliver a unique lightweight combination of performance and versatility.
