Jockey Box: Beergas, line balance, pressure

[BeerBaron1985]

Got 50ft SS coils at 5/16" ID. Figured about 12ft external lines heading up from keg to the box, calculated about 14PSI serving.

Using that same logic if I was to serve a stout on beer gas nitro at 30 PSI that puts the length of line in the neighborhood of 140 ft including the coil. Is that right?

To serve a nitro beer with a stout faucet I need that much line?

You don't actually want much line in front of a proper stout faucet as you need the pressure to drive beer through the restrictor plate. I run my beer gas pressure at 35 psi with just a 10' 3/16" line...

Cheers!

Awesome, thats exactly what I have in my keezer actually! So maybe a separate single tap jockey box with a cold plate to accomplish a nitro stout setup for homw brew festivals and such?

Yeah, I don't think it would be practical to set up one jbox to handle beer gas driven stout and conventional co2 poured pale...

Cheers!

True, good point. Then I suppose a quick disconnect straight to the stout faucet with a chilled keg is best then.

Thank you for all the advice. Now that I have the actual Jockey box, time to start outfitting it with some practical mods for a festival day. I'll make a new thread as I build it.

Another question, should I get 5/16" ID line from the keg to the jockey box instead of 3/16" line? I figure I'd go 10 feet to give myself some slack. Let me know

I only have experience with the 10' 3/16" id line I mentioned previously (which works nicely with 35psi and my Micromatic faucet) so you'd be on your own on that

Cheers!

Thank you Day Trippr!

BUMP, can anyone weigh in on the multiple diameter beer line setup? Would I just be better off keeping the entire run of line from keg to coil to faucet at 5/16"? Seems like having a choke point at the beginning of the travel from the keg to the coil will cause a drop in pressure in the coil and cause a foamy pour?
