No Ice Ultrasonic Fog Chiller Build! 121gamers 0 Views • 1 year ago

ATTENTION! PLEASE LOOK HERE FOR THE UPDATED DETAILS AND THE IMPROVED FINAL VERSION OF THIS BUILD! - https://youtu.be/od-nG93ywDA

Here are the details on what is inside the no ice fog chiller. This is my version based on what I've seen in the video made by Intocoasters and some videos of the Cumulus fog machine made by Chauvet. No ice is needed at all for this chiller to create low lying fog. It uses water vapor instead to saturate the fog and makes it heavier by making it "wetter". All I have to do is keep an eye on the water level and refill it when it starts to get low, which will take many hours with a tank this size. The mister is the most expensive part of this build at around $100-$150 for a 10 head mister with a power supply. I'll list the parts below for anyone who wants to make one themselves.

EDIT - It has been determined that the secondary tank and water pump will not be needed if a float is purchased or built for the ultrasonic mister. The mister head can float in the main tank without the need for recirculation as long as the tank is of a large enough size to not get overheated or run empty quickly. Here is a link to the float I used for my 10 head unit. - https://amzn.to/3D0h0gn I've also rebuilt mine after failing to get a satisfactory lid seal on the tote. Please see this video for details on how to improve this build - https://youtu.be/od-nG93ywDA I apologize for any headaches and wasted time/money this tutorial may have caused everyone. I'm going to leave it up because it shows the details on making it, but I highly recommend using a float instead of the second tote and pump and use a sturdier box than a tote that can be sealed easier.

Don't use it. - EDIT 10/25/21 A Kobalt tool chest from Lowe's - stock #1407437 is a much better box to use for this build. A thick bead of RTV sealant can be used around the underside of the lid to make a gasket that will seal it up tight. Others have reported good success with a variety of weatherproof tool boxes.

1- 3" 90 Degree Sweep Elbow = Lowes (inlet pipe)

1- 3" Straight Coupling = Lowes (underside inlet pipe)

3" PVC Pipe (You will only need about 4-8 inches) = Lowes

1- 3" Closet Flange = Lowes (outlet pipe) - You can use 3" pvc, but you will have to use a coupling to secure it and need a reducer to get the hose to fit over it.

PVC Cement epoxy or other glue for the pipe fittings

1- 3" x 6ft Flex Hose = Amazon - https://amzn.to/3ncPNCE

1- Hose Clamp or zip ties suitable for 3" Hose = Lowes

Silicone Caulk or RTV gasket maker for sealing around the pipes and under the lid

They are overpowered and you need to use a speed control to slow it down by about 75%, but they are made for wet environments and can be attached to the outlet hose instead of inside the box.

And this is not shown in the video because I decided to add it later, but I put a drain plug between the wheels of my tote to make it easier to empty the water out of the tote. Install it so that the plug is on the inside where it can easily be reached. https://amzn.to/3lxkTm9
