Default CO2 Tank outside Kegerator

I decided to move my C02 tank outside of my Kegerator for a few reasons...

1) So the regulator is easy to access and reads correctly
2) More space in Kegerator
3) I can use a 20lb CO2 tank

Here is how I did it....

1. a)1 inch diameter metal-hole-saw
b) Plastic fittings (male and female), 1 inch OD, 3/4 inch ID
c) Two washers, 1 inch ID

2. Make hole in side of fridge, be careful not to cut coolant lines (I started with a small hole and cautiously poked around until I was sure I wasn't going to hit anything).

3. Connect fittings, washer and plastic fitting on each side.

4. Filled in gaps with spray-in insulation (I love this stuff).

5. Put gas line though.

6. Finished! A look at the outside (Very tidy compared to my usual work!)

Nope, I filled around the gas line with the spray-in insulation.

A very timely post as I am considering doing this to mine. Are you only running one keg in there right now? Or splitting that one line to two kegs at the same pressure?

I have a dual-body regulator and I definitely want to move the regulator outside as well as the CO2 tank. I assume I could just do what you've done here but with two holes?

Did you have to worry about coolant lines? Do they run in the sides of mini-fridges? I know I had to be very careful when carving out the insulation and drilling holes in the top of mine to install the shaft.

Fwiw, I used 3" stainless nipples with 1/4" male flare ends. Very small hole required in the fridge wall. The nipples came with nuts, washers and rubber gaskets so they are self-sealing, and accept the standard swivel nut and barb for gas lines...

Cheers!

I just have the one keg in there. i can't think of a better way than what you said ( putting two holes in the wall)for your dual-body regulator. Especially since you would want to be able to control the pressure of each keg separately.

I have an old Sanyo mini-fridge, and I don't think there are any coolant lines in the side walls. But I was uber careful anyway because I would be so pissed if I ruined my kegerator (I really love it).

That is slicker!, the way I have done it means my regulator and lines are stuck there. But in my case I don't plan on moving it.

I use these to pass CO2 from my regulator (also outside the brew fridge, on a 20# tank) to the manifolds inside the brew fridge. Small holes needed, no spary insulation needed, no additional fittings needed. Plus, it's easy to disconnect the gas lines when needed (like during a move). You can also, usually, get them from a LHBS.

With the MFL bulkhead, you can also opt to adapt it to ball lock posts.

That is precisely the feed-through I was referring to (I thought they were 3" long). Easy to install and works great. I put one on both of my brewery fridges, through the back wall in the top-left corner of the fridge compartment...

Cheers!

I have a pair feeding manifolds inside my brew fridge (a two and three port manifold) off my dual body regulator. I moved towards the end of September and it was damned easy to just disconnect the gasl lines from them. Movers had the fridge out and in the truck without issue.

I'd have to check, but I think I used either a 9/16" or 7/16" drill bit to make the hole for the fitting to go through. I just put the dial caliper on one of them to see what it's max diameter was (sans the nuts and washers). Made the hole that size and it's golden.
