Yup, though it's usually the large granule form in a strainer sealed
inside the receiver tank, along with a filter element of some sort to
catch any dirt that gets in.

And on fixed refrigeration systems like at supermarkets, they put a
moisture indicating disc in the sight glass so you can see at a glance
when the system has been saturated. The disc is blue and everything's
OK, if it changes to pink you need to change the filter and check into
how the water got inside...

Next time I need one, I'm tempted to just use a regular old
refrigeration style filter/dryer with Flare connections and wangle up
a few line adapters to connect it - and add one of those nice big
sight glasses...

Wait for the raised eyebrows from the dealer mechanic, then remind
him that the refrigeration part is $20, and they wanted $100+ for
functionally the exact same thing.
