    I built a Chiller this year using a 60qt Storage bin. PVC inlet, PVC outlet with Chicken wire straight through. Used a 400wat fogger ( yes, I know small but room is not big ) Two bags of ice from 7-11. Worked well, fog dropped right out of the tube, but my auto-timer failed halfway through... Will be building a smaller version for next year with cat litter pail and save the 60qt version for a larger fogger

    Sweet! I am going to do the cat litter pail next year too for my 400 watter.. and going to build the 60qt today.. I hope! Wife is around and I haven't shared the news of how much all this cost me..er.. us.. and she wont be happy that I've spent almost $300 on a fogger and a chiller.. especially when I got this big *** gotfog chiller sitting in my garage for the past two years taking up space! If I hadn't used 4" ports on the old gotfog design, I could have reworked it to be like the vortex design.. but the tubes are just too big to make work right with the ice tray and elbow joint. Dang. Oh well.. only going to get to enjoy this for a few years.. you never know when you move into some new place that you cant set things up.. or they don't let you.. etc.

    Texan.. missed your last post.. cool info! I will build the 60qt igloo.. hoping it works well! Hell, if I have time.. I may try to get a kitty litter container.. but hate to spend money on a full pail of food. lol. Could use that for my smaller fogger tho.. but that's a manual button only.. so probably wont be using it.

    So with the 60qt vortex.. I am wondering for any cooler for that matter.. does it help to "chill" the cooler for a few hours before using it? I know the fog goes thru the ice to chill.. but wondering if like in a fridge.. you let it on for a bit to get it cold.. then put stuff in.. maybe if I let it sit for a few hours.. then drain any water out and fill up more ice.. if that would help the entire inside be colder than filling it with ice right away. But.. opening the lid to replace ice would probably let most of that cold out anyway.. so not sure its really worth it.

    Just trying to think of other ways to make it as cold as possible. One post said something like putting in ice/salt ahead of time.. even tho it will melt the ice.. maybe make it a little cooler initially..

    Is there any benefit to having some ice on the bottom right before the output.. for example.. lets assume we modified the vortex design... probably woudl work better in a longer chest than the taller one I got now.. but when hot fog goes up thru the ice.. and then falls (chilled) down the 2" ABS tube.. after it hits the elbow.. what if that emptied into another "chamber" that had some ice in it.. then an output port.. so that the chilled fog might get some extra chill.. I was thinking that after its all nice and chilled and starts going thru the output tube at the top.. it may "warm up" a bit on the way down before it exits... the ABS tube itself is no doubt warmer than the ice.. so as the chilled fog goes out.. rubbing up against the ABS tube.. it probably warms up a bit again. So that's why I thought.. what if it went thru a 2nd batch of ice right as it exits.. to help chill it up again? For that matter.. if I use the bag on the exit.. to help spread it a bit.. what if I do what that one post said.. put ice to old the bag down.. which adds a bit ore chill.. is that basically the same thing as what I am suggesting?

    LoL....Man you sure are putting a lot of thought into this just for one night. It pretty much is what it is. You are only going to be able to do so much with a chiller and you can not get ice more much colder then if it was 32 degrees or 10 degrees. The results will be the same.

    If you could find a way to trap the fog in the chiller for an extender period of time then release it when needed that would probably be the only optimal way. Just remember you can only get vapor so cold regardless of temp. I had a couple ideas for something like this but never got around to trying it out.

    Just got around to uploading the pictures of the fog chillers I built for this year. All three are Vortex designs built into Igloo 60 quart "Ice Cube" coolers. The shelf support is made from 1/2" PVC and the shelf itself is a cut down light fixture grate. All the pipes are 2" ABS.











    A few items of note... I had to buy a relatively expensive hole saw to do this. The 2" ABS needs a 2 3/8" hole. I used a Rigid saw and mandrel from Home Depot (total cost around $30). The light fixture grate cuts easily with a set of wire cutters and was very easy to fit. I used a ratcheting PVC cutter which made things go very quickly as opposed to a saw. The coolers were painted with Krylon ultra flat black camo paint. Unfortunately, it doesn't stick very well and it's already peeling off.

    I did one test with about a 1/4 load of ice. The fog stayed low and came out very cold to the touch. I expect these will work well when fully stocked. I'll be using all three with Chauvet Hurricane 1250 fog machines. One will pump fog out of a witch's cauldron. Another will pump the fog through around fifteen feet of perforated 2" ABS pipe behind one of the graveyards. The third will be in a van putting fog out through the open side doors.

    I'll take pictures of them all in action and post them after Halloween.

    Man looks like you are set, should look really good. 1200w or should I say 800w..LoL In a cauldron should look sweet...LoL

    I never thought about using that light fixture cover. Do you think that stuff will get brittle when it get cold? They look great. I always cringe when I have to cut into a cooler which is why I went with the trash can coolers. I can't bring myself to cut a perfectly good beer can chiller...LoL

    One thing I would add to keep the ice from falling through as it melts is get some screen like you use on your windows and line the top of that grate. Might also help slow the fog down some too giving it more time in the ice. That stuff is super cheap and would keep the ice from going to the bottom of your cooler as it melts.

    Yeah, I forgot to add that I had wire mesh that I'd be installing to keep the smaller pieces of ice from falling through. I don't think it'll be too big of an issue however because the ice tends to stick together rather than shrink and drop.

    I also made sure the pipes were above the level of the drain plug.

    That should work pretty well Mark. I bet a straight Vortex design in that size can would work about the same however. The additional ice creates a huge increase in surface area which is the biggest factor in cooling the fog down.

    That reminds me of two things I forgot to add on my original post... I did not end up sealing the ABS pipes where they penetrate the cooler. They fit very snug and don't leak. Instead of weatherstripping the lid, I'm just going to tape it closed with gaffers tape.

    I like the idea, I think it would work great. The dryer duct should slow the fog down enough, then having it drop through the ice as well makes it even better. Only thing I am curious about is do you think there will be enough to force the fog out once it has dropped? I like the drain cover idea, that is slick...

    Another thing I did that I just remembered. When I made mine, just below that lip on the inside where the ice tray sits. I put some 2" bolts in there to help support the tray in case it slid down or tried to. Since you are not doing an actually vortex design you won't need that though.

    Weather is usually our worst enemy here in the great white north. Normally it is very cool, so even a fog chiller doesn't help much, but that doesn't stop us from trying. This year the forecast is for a low of about 36 (2-3 celsius) which is not too bad. Still getting the fog really cold is of utmost importance if you want it to lay down at all. I used a vortex chiller last year (spent the money) but even that didn't do a very good job.

    This year rather than focusing on longer chamber time or ice contact, I'm going with dry ice. The local 'gas' supplier sells dry ice in a cube/pellet form, which would provide the surface area I need, and it is of course way, way, way colder than regular ice.

    This will of course require some special handling but I'm hopeful that this will solve my problem. Very interesting discussions about chillers, I'll post my results in a few days, and look forward to hearing how all the other plans worked out.
