Overview
Overview
The system uses two coolant loops to use heat
released from the engine to heat the A and B
component material to the target temperatures
defined on the ADM (PD).
The engine coolant loop (gray) circulates heated
coolant from the engine (EE), through the heat
exchanger (HE), radiator (ER), and back to the
engine. Coolant in the proportioner coolant loop
(black) captures heat from the engine coolant loop
inside the heat exchanger (HE) near the radiator.
