Depends how many snakes and how big if I can help you or not, but here’s what I’m doing.
I bought a wine cooler from Best Buy for $104.00. I’ll include a link to it for specs. It’s a thermocooler so it’s super quiet and uses very little electric. It’s got a great glass door, awesome seal, a circulating fan, light, and the interior is like a cube- no cut in from a compressor. It is designed to cool at 55 degrees, but is adjustable. I just took some pictures of some of my modifications, if you are interested let me know.
Here with the boxes inside-

I added an aquarium air pump to pump air into it on a timer, it goes into the bottom left container with water and an air stone so the air gets chilled a bit. I added another air line for exit with a tiny in-line filter and check valve.
Very small aquarium air pump I tied to the back with electrical ties. I ran the tubing up into the top corner and into the box.

I am only brumating Brooks, Goini and rats (seven snakes) so this thing seems perfect so far. Temps were in eighties until today here in Ft. Lauderdale. The picture shows about 59 degrees but I was opening the door and stuff, it is normally right on 55.
This WS is the “youngest” I am brumating.

This lucy (She Devil) rat is the “oldest”. Both fit inside those ZipLock containers, bagged with no water. I am cooling them for about seven weeks. We’ll see how it goes...

This is a great timer I got at Big Lots for seven bucks- it can adjust every fifteen minutes on or off twenty four hours-

Here’s a link to this Avanti wine cooler like the one I bought.

Heres the manufacturers picture of this thing- works great for me so far.
