Heli-Preheat System – Enstrom 480 with Rolls-Royce RR250-C20W
Preheating is accomplished using electrical resistance heat in the form of thin surface mounted pads sized and shaped to fit various parts of the aircraft, including the engine oil tanks, and main rotor transmission. Power is routed to the heat elements through a dedicated wiring assembly with circuit overload protection. The system is self-regulating through design. Heated components reach an average state of thermal equilibrium in six hours.
This preheat kit when installed will supply 292 watts with a 2.5 amp draw at 115 volts.
