Cooler,
Two 4" dryer ducts (short sections), silicone caulk, tools to cut plastic,
screen or netting, Flexible dryer hose, two 90 degree angle ducting, one
4" to 2" reduction ducting
I
built this out of a $15.00 Coleman cooler I got at Target the whole thing
cost about $25.00. I started by marking the holes on the sides of
the cooler to the size of the dryer duct and cutting them out. I
first drilled holes around the line I marked then knocked out the plastic
and foam core then smoothed up the edges until the dryer duct fit snug.
I used silicone to seal the duct inside and out, it takes about 24 hours
to cure. I then fitted netting around the inside of the dryer duct
on both sides to prevent ice from falling out. I then put flexible
dryer hose on one end and a set of 90 degree angle ducting pieces on the
other. A reducing duct piece (4" to 2") will attach to the angle
pieces. The 2" end sits in front of the fogger nozzle and delivers
the fog to the cooler and ice, then blows cool fog out of the dryer hose
end creating a low lying fog.
I
use regular ice from the corner liquor store and fill the cooler to the
top with the ice sloping from the top to the bottom of the in/out ducts.
This takes about three bags. The ice needs to be high enough to cause
the fog to go through and around it, but not covering up the ducts. Some
people may try dry ice in the cooler, I hear this works well.
