Fixed Wing Preheat System – DHC-8 Q400 with twin PW150 – 115 Volt

Full aircraft preheating is accomplished through electrical resistance heat in the form of thin pads and belts sized and shaped to fit various parts. The pads are surface mounted with a bonding sealant/adhesive. Belts are secured around the perimeter with cable ties. Heated items include, engine accessory/reduction gearboxes, fluids, batteries, and attached accessories. Power is routed to the heat elements through a dedicated wiring assembly with power indication and circuit overload protection. System is self-regulating through design. Heated components reach an average state of thermal equilibrium in approximately six hours.

* DC730 bonding sealant sourced separately and required (12 ounces approximately).

A complete aircraft system supplies 2520 watts with a 22.0 amp draw at 115 volts.
