Hi I was thinking of getting one, even just for storage with neoprene cover. I was watching a review and the guy said it leaks through pvr? He didn’t say which company. Are there 2 versions now from different companies? According this site Keg King is 540mm and I saw dimensions in another drawing - looked very similar and was 586mm - but that was bottom to post top? So 540mm might not to top of post. Anyhow as I understand there is a new cap with mini lid, so locks inside and pressure keeps it sealed?

I would like to try pressure fermenter and I need 590m clearance for my bar fridge. Not sure how much clearance with spunding valve on .. I have 3 dimensions 540mm according to this site (ceo keg king) 559mm, and 586.9mm .. different sources on net.

Also cleaning with a heavy krausen sometimes can be stuck on, and not being able to boiling water might be hard to clean...
Thanks

Spunding valve is no higher than a standard ball lock fitting, as i understand it FK JR is only made/sold by one supplier/manufacturer. The neck is large enough to get a hand in to clean so you don't need use boiling water which would melt the tank.

This is a KK FKJ, I'm not aware of any other manufacturer/supplier.
The pressure relief valve doesn't leak but is set quite low, mine holds 15psi no problem, starts to vent at about 25psi.
I've got 2 of them and they're really handy, highly recommended.
At 638mm high though it looks like they wont fit your fridge unfortunately.

My local LHBS carries the Keg King Fermenters and says they are awesome.

He said as long as you clean them after you package and don't pressurize them up past reccommended then they work really well.

I have not personally used though so take with a grain of salt

I guess you dont really need more than 25 psi,

Thanks cheers

I guess you could add a tube to the grey out let and it sits lower, or just turn them to lowest height,

How tall is it to the top of the post with grey ball lock? I need 610mm clearance ...

thanks

You can buy 15PSI PRV and go with no spunding valve.

That's a piece of copper pipe balancing on the top of the posts, pic 2 has a bit of parallax error it's exactly 603mm, pic 1 was an attempt to show the posts.
As per previous photo #3, it's 638mm to the top of the grey disconnect, I've got a few different disconnects, and none are any shorter than the one shown.

Thanks sounds like a plan, is there a reason you would need more than 15psi anyway? When fermenting that is, ? I can anything I need in other cold fridge

In my opinion 15PSI is plenty. Also gives leeway if it's not exactly 15 if that makes sense.

What do you guys use for? Small batch or fresh worts,

I use kits, so I was think how I would be able to keep 5 litres wort and store until it adds up to 18 litres with extras, if I make same beer or maybe just add all together and make a mix...bit different.

Its a pity they don't make a wider one that would take 23 lt? Its the height I need to bigger than 61cm, and for most people if using a small fridge would be the same.

I use mine for small batch (12L) and cider (15L) little to no krausen on cider, FWK's are typically 15L due to shipping costs, and you usually add 3-5L of boiled water to make up the batch, if using a FWK I just dump it in without the extra water, ends up a bit stronger, and not exactly to style but still makes excellent beer.

Is there any way you could afford $200 for a different fridge? Mitsubishi Electric Frost Free Upright Freezer | Fridges & Freezers | Gumtree Australia Penrith Area - Claremont Meadows | 1266279966 is an indication of what's available, a freezer is preferable to a fridge, much better insulation helps with cooling, and also keeping the heat in if using Kveik or in the winter, and they usually have a better compressor, so are quite a bit cheaper to run than a fridge.
The floor space is pretty much the same, small fridges just tend to be shorter. Gumtree or FB's market place are good starting places to look, one of mine actually cost $80 but it took a while for it to come up, so patience is necessary if you want a real bargain.
Let us know if it's something you'd look at, as there's a couple of things you need to watch out for.

mmmm It is a possibility, I have another beer/keg fridge - If I could swap for one of those fridges that have large freezer area/ and fridge. Would it be possible to control the temp of each section - somehow. Is there a controller for that, I have inkbird.. I cannot get another larger fridge, that's why I like the bar fridge size for fermenting. I had this crazy idea of getting two juniors and daisy change them when fermenting but will be about 20cm too large.

Hi,

I have a couple of these now and I use them for normal and pressure fermenting and for serving kegs.

I know some on here won't like that but they work fine for me.

I have made kits to 18L in these and when the brew is finished I CC and then connect up to my taps. They have worked fine, my beer normally doesn't last very long so Im not worried about leaving the beer on the trub or oxidization.

For my AG I ferment in one of these and then closed transfer to another for serving.

The only tip I would have is to lubricate the posts that come with them as they can be a bit tight with some disconnects.

Ill be getting more of these soon.

Does anyone know why there is the outlet part near the neck with the small bung? I recently bought two and keen to try them for small batch ferments and also as kegs.

So you dont mind losing 5 litres?, I was thinking of maybe 2 cans, and 1 fermentables to bring to 36 litres. Keep one under pressure and ferment, the other under pressure without yeast until other ready. Would a recipe like that work?

The only way (practically) to have separate control of fridge and freezer is if it has two compressors, and only the really high end manufacturers do this.
I've got a Smeg dual compressor but in reality the temp difference when trying to use the freezer at -18c and the fridge at 18c+ just results in the compressors running almost continuously.
Have a look at some of my fridges for rough ideas about what height is required, the small one is a two tap serving fridge that doubles as a fermenting fridge if needed. The Smeg is really tall but having the fridge above the freezer makes for an easy height (no bending over)

If you fill a keg with wort without yeast it WILL become infected, sooner or later, probably sooner, don't confuse this with hot cubing, they're very different things, so no, it wont work.

No, Im not worried about the 5lts, just makes it a bit stronger but not too much extra bitterness.

Why dont you just hold off on the other kit till the first is ready or are you talking about using two different extracts for one beer?

I dont know what the effects of leaving a kit open without yeast. Maybe it would be prone to infection if your process is not spot on? I would just run both at the same time if that was the case.

I believe that is because they use the same mould for something else
