Fog Chiller Testing

After testing all three fog chillers in our last video, we have results about what works and what doesn't, and what each style of fog chiller is best for.

I just finished putting it together and it turned out pretty good. I cut a 3” hole on the two opposing corners and glued in two 3” to 4” metal reducers using 5200 ($24 for one tube!) while making sure to hit all the seams. There’s 8’ of 3” duct zigzagging back and forth flat on the bottom of my 70qt igloo and I have 12’ of perforated 4” plastic drain pipe for the output to run through our graveyard. Even though I haven’t tested it yet I’m confident it’s going to work well, fingers crossed.

Awesome, let us know how it works out.

Interesting, which one did you like the best? It’s hard to tell with that wind.

The wind definitely made it difficult to test. For all out low lying fog, the best solution seemed to be the storage tub chiller. But, I don't believe it will work for our Halloween display, as we need about 4-5 hours of fog. The ice chest is the only one that I would trust for those kinds of times. We actually used it last year for a Halloween party that went from about 7pm-3am. It was mostly ice water by the end, but it still put out fog about knee high.
In the future I want to rebuild the ice chest chiller with some aluminum piping that is air tight, and run the chiller with ice water. The idea is that the water will conduct heat better than air, so water contacting the whole piping will work better than just the ice and cold air inside the ice chest contacting the tubing.

I’m going to Lowes tomorrow and pick up a semi-rigid flexible aluminum duct and see if I can rig it in the bottom of and old igloo I have. It should be more water tight than the foil type.

The ones from Lowes usually have the label stapled to it, so make sure to grab a tube of silicone sealant as well, it will leak from the staple holes. Ask for an underwater approved sealant, I can't remember the name off hand but if I can get there tomorrow morning I'll get you the product. It comes in a small tube, in my Lowes it was near the plexiglass/lexan. I originally used PL300 foam glue to seal the tubing to the holes in the ice chest, but found out the hard way it wasn't water proof. Let me know how it turns out.
