walk-in cooler / beer line length

[Stymingersfink]

I am building a walk-in cooler to keep my serving kegs in. I would like to run a line into the kitchen in my house but its a very long run of around 36'. I am assuming it can be done, because I think they do stuff like that in commercial bars. Does anyone have information on how to determine line size and pressure?

You'll need to plan for a glycol chiller and insulated beer lines to get that length of run set up correctly.

Thanks Dcpcooks, thats exactly what I was looking for. I am going with a tower and lines from Micromatic. They also have chillers available.

I'd start with the only beer line length calculator worth using.

Plug in your distance, rise, pressure, etc and it'll kick out a length that works with solid PVC line.
For barrier tubing (eg: Bev Seal Ultra 235) multiply the given length by 1.5 and you should be in the ballpark.
Using 12 psi and just a 1.5' rise (from middle of keg to faucet) assuming kitchen and cold room are on the same level it appears ~36' of 1/4" ID PVC ought to work.

And Dcpcooks is correct, you're definitely going to need to run a cooled trunk line over that distance...

Cheers!

For that distance, off the top of my head I'd recommend 1/4" ID bev seal ultra 235 line. 36' may actually be a bit short for proper pressure drop, but if you use a trunk line with glycol chilling, and then use perlick 650ss faucets, I think it could work well.

I personally have 14 perlick 650ss faucets on my coffin box from the walk-in using 8 ft of the 1/4" ID bev seal ultra. Some of my pours are foamy, but with the longer lines that you would have, I think it would be much better, especially if your lines and faucets/towers were chilled with glycol.
