|My old fog chiller was based on the 'fog on the rock' methodology by having a tube going from
the fog entrance to the exit with ice cubes surrounding it. It did well with short, quick bursts but
not very well with long durations from the fog machine.
Here is my modification
|The chiller now will have the right side compartment filled with ice
and the fog will need to travel through the ice. To keep the fog
from exiting back up through its entrance, a dryer vent should act
as a one-way check valve for force the fog through the ice and
hopefully chill it better for low lying fog even with long bursts.
The screen in the divider may not have been necessary, but I was
I will most likely need a latch or strap to keep the lid down.
|The dryer vent was placed over the
incoming fog hole with silicone sealant.
|The exit tube received a mesh screen
over it so the ice cubes won't slide out of
the ice compartment.
|As mentioned, maybe not needed but I
was bored and thought I would give the
fog another passage way instead of just
down through the top of the ice chamber.
|This was all the ice I had in my freezer for the first test.
I think things still turned out pretty well as I didn't have
to pulse the fogger to make low lying fog. It was kept
full on (well during the re-heating cycles).
I did have some leakage around the cooler and also at
the initial top entrance when the fogger would spit
spatter a little fog during the re-heating.
|Here is when I opened the cooler at the
end of playing. As you can see, this fog
isn't cooled yet since it hadn't been forced
thru the ice.
