Does anyone have a real good way of cold crashing and keeping the oxygen out?
I came up with this setup, seems to work pretty well really.

Applying positive pressure with CO2 as you've done is most certainly a great way to ensure you don't suck back in atmosphere.
That's pretty much what I do as well as I cold crash once in the keg on CO2 pressure.

I do the same as you guys when cold crashing but am always concerned my reg will over pressure the fermenter as it seems to creep up after a while. There is a pressure relief on the fermenter but not sure it would vent enough to prevent over pressure so I just periodically turn the valve on to let some co2 in and then shut it off again. Kal, I know you use Micromatic regulators, do they maintain that low of a pressure consistently? Thanks

A regulator should never over pressure. if it does, it's not working properly. The whole point of a regulator is to regulate the amount of pressure it passes. It's not brand specific. Any regulator that allows more than the set amount to pass is not working correctly. That said, there are some cheap brands that do not work correctly. I own 4-5 regulators of various brands (one in the kegerator, one in the conditioning fridge, and 3 in the keezer where one is Nitrogen and the other two are CO2). All work correctly.

I have an older taprite reg and works fine around normal pressures of 10 psi but does not work well in the 2 psi range. I am looking at purchasing a Micromatic and just trying to find out whether they work in that low range and sounds like they do. Thanks for the response.

My 2 cents.
I have a Tee on the top of my conical, on one leg is the gas fitting and on the other I have a very large balloon. I inflate the balloon with only a fraction of a psi. The balloon will deflate as the beer is cooled, both back filling the volume and by some carbonation into the beer. I re-inflate the balloon as required.

What a great idea! Sure solves my problem with poor pressure regulation at the low end. Thanks David.

What size conical is that?

isn't this in conflict with your recipes, which describe racking to a brite tank, crashing and then kegging?

I'm guessing his brite tank is his corny keg.

I recommend cold crashing once in the brite tank if possible as gelatin will work better, but I don't have an easy way to do this so I don't. I've always been happy with the results.
Not that all beers are different too - I don't always use a brite tank, for example.

It's the Half Barrel Connical from SS Brewtech.
I really like it.

That is a great idea, I think I will add that to me setup.
Thank you

I'm going to pull the trigger on one this week. I've already got the 7 gallon and am very happy with that one

I'm sure you will be happy with the 1/2 barrel conical. I bought one in the brewmaster edition and is probably the best piece of equipment I purchased for my brewery. I have the CIP spray ball setup that makes cleaning and sanitizing a breeze. Also built a chiller from an old air conditioner for cold crashing. Streamlined the whole process from BK to keg.

Yeah - I rack from my conical into 2 cornys, 1 goes in the conditioning cooler, the other in the keezer - by the time its carbed, the first beer poured is a bit cloudy, but it clears up real quick - definitely worth not adding the extra step of moving from cold crash corny to keg corny. Life is too short for that stuff.

I ferment in a large upright freezer, equipped with a temp controller. So cold crashing is no work at all. I simply, drop the yeast out the bottom. Then turn the freezer down to 28F. Let set a day or two, with my CO2 at about 2 psi. Then just push nice clear beer into 3 kegs via the racking port.
This works well for me, but everyone has their own system. That's what makes this hobby so much fun to share.
