Produced in partnership with Powervamp, the Coolspool 29 is used extensively on larger twin turbine aircraft and helicopters where additional amp/hour capacity is required to maintain voltage under load.

Upper Fadec limits vary according to the manufacturer’s software and for this reason two versions of the Coolspool 29 are available.

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.

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 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.

** Peak amps is a theoretical calculation of the instantaneous current from a momentary dead short across the battery terminals. It is not representative of the power delivered at the aircraft plug which is significantly less, due to cable losses and other factors.
