Seems to me, any technique used to remove all the moisture from the air
would nullify any energy savings, no?

The heat exchanger extracts the heat from the dryer exhaust and
transfers it to the incoming replacement air. The damp (cooled) air is
vented outside. I'm not sure what the efficiencies are, but I believe
that the (already in use) dryer blower does all the work.


So it must do it without the air actually mixing?
Or do the physics of it all dictate that the moisture will stay with the
cool air?

You were right on the first guess. I'd be willing to bet that you could
build your own without too much dificulty.

I DAGS on dryer+"heat exchanger" and got 387,000 hits.
