Due to the extra starting power provided by the 26V batteries, turbine engines will experience faster and cooler engine start than most ship’s aircraft batteries (the turbine is spooled to more revolutions per second before fuel is injected). Thus, turbine life will be extended because there is less stress on the starter and other engine components. This will preserve the aircraft’s costly batteries and help lower operating costs. Your airborne, on-board battery can then be saved for emergency use only. As a START PAC® secures all your engine starts, this unit will ensure that you have no downtime.

It can be used in remote locations using battery power to give extended time for cockpit maintenance checkout. Its large battery capacity will allow extended usage time when no AC power source is available

Additionally, the unit can be configured for 110 Volt or 220 Volt AC input.

The 3326 Special is coated in an environmentally responsible, low VOC powder coating, which protects it from wear, tear and extreme weather conditions. Additionally, an all-weather cover is also available as an option to protect this unit further from inclement weather and to gain the maximum performance and product life.
