PT6A (Large) Engine Preheat Kit -115V

This system is purchased and installed per engine. It runs off of a 115 volt power source. Contact us for additional information for connecting systems to a single plug location.
Turbine engine preheating is provided through the use of pad heat elements on the engine nose case, and accessory cases. This heats important items like the FCU, bearings and oils.
For operation below freezing, the complete aircraft should be heated by incorporating battery and avionics preheat.

This preheat kit when installed will supply 753 watts with a 6.5 amp draw at 115 volts.

* Required Bonding sealant sold separately. Quantity 2, PN: TU02788
