Krups Beerteender Conversion

Picture of Krups Beerteender Conversion
Since I homebrew, I have wanted to keg my beer and serve it chilled from a tap. However, I have not had the money, nor the space, to invest into a full size kegging operation. I wanted something that looked attractive, was small, easily stored and wouldn't cost to much. This project really fit the bill. I think I spent just under $100 in parts, and since the Krups Beertender was a gift I didn't have to spend any cash on that.

I updated this on 1-27-14 with somethings I learned while using it:
-The Edgestar tap is good, but the regulator is a pain. Buy a real one, and the basic adapter to paintball CO2 route if you go that way.
-Don't bother with the glue
-If you go with Edgestar regulator check the comments for fittings.
I got this idea from: https://www.youtube.com/watch?v=JbLjPP7W5Q4

Step 1: Gather Needed Items

For this I used a:
Krups Beertender (model B100)
The Edge Star Mini-Keg Conversion Kit
Drill - If you have a right angle drill, i would use it. Space is very limited
1/8" Drill Bit
7/32" Drill Bit
1/4" Drill Bit
Teflon Tape
*Loctite Clear Silicone Water Proof for Aquariums (if you are able to find specifically food grade sealant, I would use that. However, the aquarium sealant is perfectly safe once cured)
Mini-keg

*This isn't needed and this is what came apart when I had a regulator fail. I rely on friction and have had no problems

Optional
*The 'Adapter II' (make sure it goes paintball to 1/4" right-hand threaded)
*Brass 1/4" to 1/8" Reducer
*Brass 1/8" to 1/8" (short)
**The Adapter
**Regulator
20 oz CO2 Paintball Tank
C-Wrenches
Locking Pliers 

*See comments regarding beer gun regulator nut and 1/4" to 1/4" npt
**I had some major problems with the EdgeStar Regulator and went to a normal regulator and adapter for the paintball co2 tank.

My local sports store sold me a tank for around $25. I switched to this, because the 16g CO2 cartridges run you about $2 a piece, and it costs about $5 to fill the much larger canister. It should save money in the long run

Please keep in mind, with the larger CO2 tank you are dealing with very high air pressure. I used brass fittings, since they can take the pressure. I wouldn't use plastic or PVC on the tank side of the regulator.

Hey, well done! Kudos!

As I am a homebrewer, too, this looks great for small places. I will give it a try. Probably, won't find the paintball cans here, but who knows!?

Two quick questions:

  1. Will I be able to reuse the kegs and put my own beer in it? I assume that is your idea too, isn't it?
  2. Should my beer be already carbonated or the CO2 is enough for that?
cdburkhart (author)  montalli2 months ago
  1. . Yup, the mini kegs are reusable. I think the manufacturer says the have a 10 use span. Just clean them well and check for rust.
  2. You can force carb or naturally carb. If you are naturally carving, you want to use less priming sugar, like half to three quarters as much. Unless you find something cheaper then the 16grams co2 bulb, I would naturally carb. For me I can get 16grams bulbs for about $3.50 each. My small tank cost about $25 and is $4 to refill and holds about the equivalent of 40 single use bulbs..

Hmmm... looks even better!

I will try to find those tanks for paintball. In this case, I guess I can carbonate the beer faster (I would get to drink 2 weeks faster than usually :) ).

Thanks!!!

Let me know how it works.

For what its worth, I never went to forcing carbing with this because it felt like more hassle then its worth. To carb all four at once you would have to build sort of manifold to get to all the kegs at once. Or you carb on at time...and that seems like not enough volume at once for the downtime required to carb...

Nice work! How long does this keep the mini keg cold?
cdburkhart (author)  Hockrockit273 months ago
For a fairly long time. The Beertender uses as Peltier cooling system which is effective at keeping things cold, but not effective at making things cold. So if you stick a room temp mini-keg in there it can take up to 24 hours to chill it. But if you chill it in your fridge before hand, the Beertender will keep it chilled as long as it is plugged in.

hey man, was doing this project and i ran into a few hiccups. i have the same exact edgestar regulator as you and i went a different route other than the adapter 2 right hand thread, 1/4" to 1/8" reducer and 1/8" to 1/8" nipple, i went paintball fill valve with 1/8" outlet to 1/8" short to 1/8" elbow to 1/8" short. the problem is the 1/8" seems to be a little small and threads dont tighten all the way. have you had any problems or have to remove the pin inside the regulator female connector? i took the male end from the 16g co2 housing to lowes and it was bigger than 1/8". it was 1/4" compression fitting but i tried a 1/4" compression thread male nipple and the threads seem to be off. it seems to be the 1/4" compression size fitting but with regular threads. any advice? also on another note and idk if you know but on ebay there's an adapter to change out the tap handle, where you can put your own tap handle on there. just another touch you could do. also, great write up!! i hope to get this regulator thing figured out. i might just try a butt load of teflon tape on the 1/8" nipple and say some prayers. and fyi, i have the exact same edgestar regulator you have. i know they have two different sizes, i believe a 1/2" threaded one and the smaller one which you and i have.

I need to look up the adapter, thanks for the heads up.

Tamorgen used a Beer Gun regulator adapter and made it work that way. I have moved away from the Edgestar regulator since I had two fail on me :(.
sorry to hear that they failed. I think i might just skip the whole edgestar regulator now. im getting fed up with trying to find the right fitting. i tried the 1/4" flare and no luck. there's no local homebrew stores around me to help. im glad the beer gun adapter worked for tamorgen. i hope i will find this product online and try it. i saw a check valve that was similar.

Great DIY, but I have a question about the Paintball conversion. You say "Adapter II", right handed thread, but what I've found here is that "The Adapter" is right-handed, and "The Adapter II" is left handed.  Can you verify which one you bought?
cdburkhart (author)  tamorgen8 months ago
It really depends on what regulator you are using.

If you bought the kit from Edgestar, you can recieve one of two regulators from what I have heard.

I recieved the silver one with a smaller port and used the Adapter 2, with right hand threads, since it was easier to step down.

For the other one, I don't know

The main difference between the adapter and the adapter 2 is thread size. The original adapter is a match for the standard CO2 nut. The Adapter 2 is a match for the regulator stem and you can screw directly into the regulator, and forgo the nut/stem.

The Adapter 2 comes in both right and left handed threading. Right hand threading will fit the standard CO2 regulator, while left handed will fit a nitrogen regulator (which can regulate CO2 as well).
http://www.homebrewing.org/Paintball-Adapter-II-right-hand-thread_p_2637.html Adapter 2 right handed
http://www.homebrewing.org/Paintball-Adapter-II-left-hand-thread-_p_2638.html Adapter 2 left handed.
So, I've made the conversion, but I'm having a devil of a time figuring out the threading on the regulator. For now, I'm running the CO2 cartriges, but the first two cartridges leaked like crazy, and I had to go onto the third. The third only got me part way through the keg, so I had to buy more at a local home brew store.

I bought the parts you mentioned for the paintball tank conversion, but my regulator seems to be metric. Problem is, most big box hardware stores have an awful selection of metric, and nothing that converts NPT to Metric. I thought the regulator was going to be M10, but nope, I had ordered a 1/8" to M10 converter off of Amazon, and it was to small. It is likely a M12, but xWhat? M12x1.0 or M12x1.5, or M12x1.75. I've ordered both the 1.0 and 1.5 this time around, and hopefully one of them will work the next time my CO2 cartridges is empty. I'll post what it ends up being once I know for sure.

I finally figured out what the fitting is for the CO2 regulator. It's not metric, and it's also not the 1/8" NPT fitting, although that was a close fit. The problem is the fitting would thread in, but slip, and break the seal. Thats one of the reasons I thought it might be metric (that, and the idiot at Home Depot said it was metric). NPT fittings are tapered, and that's why it was slipping.

After ordering and returning different adapters, I finally took the regulator down to my local Ace hardware, and spoke with their plumbing guy. He showed me tapering on the threads. It's hard to see on a 1/8" fitting, but it is there. It's easier to see if you look at a 1" NPT fitting. NPT fittings are meant for plumbing (water), and not gas. The CO2 regulator is a straight thread, and those threads are harder to find.

He suggested I call Roberts Oxygen, but I was told they didn't have anything that small. I was resigned to perhaps investing in a standard CO2 regulator and tossing the BeerTender adapter aside, just using the plastic parts and tubing.

Next I went to my local Home Brew supply store, and showed the guy there what I had and the issue I was having, and we went over to their fitting shelves, and they had several pieces that fit the Edgestar adapter. The thread is actually a 1/4" Flare fitting, so that's what you actually need. They had a part for $2.50 that converted the 1/4" flare to 1/4" NPT, and they called it a Beer Gun regulator adapter. All I needed now was a 1/4" NPT to 1/4" NPT coupler.

Armed with that new knowledge and the adapter, I went to Home Depot, got the coupling, some gas fitting thread tape (teflon is not for gas), and built the adapter.  Now, I can finally hook my paintball tank up to my Beertender

hey!!! thanks, for all the information. i went to a local hardware store and found an adapter like the one you mentioned above(beer gun regulator adapter). they had a 1/4" flare to 1/8"npt elbow which would of worked great, but the flare end would only turn a few turns and stop and not thread all the way onto the female regulator end. so im still at a loss. the 1/8"npt would of threaded perfectly into the paint ball fill valve im working with. im not convinced the 1/4" flare is it. would your's only turn a few turns as well? i pretty have the same story as you with considering a different regulator and being ran into circles going to lowes, calling edgestar, going to hardware store, talking to plumbers, etc. i'm about to give up and go with a different regulator. is the threads on the beer gun adapter different than standard 1/4" flare fittings? from the looks of the picture above, it has way more threads than the one i tried at the hardware store, any help would be awesome, thanks
tamorgen gogojjt7 months ago
Mine only went in a few threads, but it was enough. There should be an o-ring on the regulator, so that may be what is stopping yours. You may have to use a couple of wrenches to tighten it in completely, and don't forget the gas tape.

BTW, it's been working great since I found the correct adapter.
Looks very cool... Doesn't Paintball CO2 have a lubricant in it?

I asked when I bought mine, they said they didn't add oil. But that is a fair note. Always ask.
