HEAT TRANSFER SYSTEM
See Figures 13 and 14. Water is heated through a
three stage heat exchange system which utilizes
vacuum exhaust, engine coolant, and engine
exhaust.
Stage one utilizes vacuum exhaust heat blowing
over two radiator-type heat exchangers in series
prior to discharging the exhaust into the atmosphere.
When the tool valve is closed, the water bypasses
from the pressure regulator manifold to the water
box through the vacuum exhaust heat exchangers.
Water then flows from the water box to the water
pump, where it is pressurized. It then travels to the
pressure regulator manifold.
When the tool valve is open, the water flows through
the stage two heli-coil heat exchanger system which
uses heated engine coolant pumped over copper
coils. The pressurized water flows through the
copper coils and collects heat from the engine’s
cooling system. The water then flows to the stage
three heat exchange system.
