Default Why? Fan in the Keezer? Temp Comntroller in the Keezer?

I have seen some great Keezers here and I am planning on building two (2) two keg Keezers so I have some questions...

PART ONE: Why? Fan in the Keezer

Yes, I know cold air settles, but in one of these 5 or 7 cubic feet freezers why all the concern about air flow?

My Points so you can help me understand:

I mean air moves around on its own with out any fan.

and

Even if it did not and the cold air is at the bottom... that is where the beer is being drawn from,,, so why not just make sure the bottom of the freezer is the correct temp or even maybe a degree or to lower ...


PART TWO: Temp Controller in the Keezer?

I would like everything self-contained and not have pieces all over the place... So I would like to put the Temp Controller on the inside of the Keezer-collar,,, (the wooden one I add)....

I have almost busted off the one on my current keezer a few time moving it because it is monuted on the outside... and the same for my fernemtation freezer... I have to move two things all the time and I would like to move one...

The only reason I can see not to do this is moisture?

Default keezer

There are no fans in my keezer with six kegs on the floor and the beer is always cold. I do have a little condensation which the fans supposedly reduce/eliminate.

I built the temp controllers into coffins so there is no issue when pushing the keezer around. If you are worried about moisture affecting the controller you could build a small box around it on the inside of the collar.

AHhhhh,,,, "condensation" something I had not considered... and something that "I got in Spades" in my current 6 Keg keezer but I think it is mostly because of the fact I am lazy and don't like cleaning the "lines"... so when there is no great need to have all the taps running I use "Cobra-Heads" and open it up to get to the beer.

Thanks,

DPB

The wooden collar does not have cooling cools running through it like the walls of the freezer, so it can be up to 2 degrees warmer. Since this is where your tap and lines run, the temperature differential can cause condensation issues. The fan just helps equalize temperature through out.

I have a Johnson external temperature controller that is just mounted on the backside of the collar. I drilled a small hole and ran the probe inside. I filled the caps in the hole with plumbers putty.

My keezer is 8 cu ft. and yes, the fan DID make a difference. I just bought a tiny AC powered fan at Radio Shack and wired it directly to a plug and plugged it into the same outlet the keezer is plugged into.

You want to keep the tap and beer lines close to the same temp as the kegged beer. If cold beer is suddenly warmed by beer lines, tap faucet, warm glass, etc it creates foam. Thats why the first 1/4 pint that is poured foams more than the rest. I usually pour a 1/4 pint, set it aside and fill my wife's glass (who likes less head, joke away!). Then come back and fill the rest of my pint glass.

I don't have fans, but put the beer line inside 1/2" copper pipes. The cooler air from the fridge is conducted along the pipe, keeping the beer line and tap cooler. No fan necessary. This is on a kegerator though, so not sure its applicable for your question.

I have my ebay temp controller built into the wooden collar on my 14.8 cuft keezer with no issues.

Helps with my condensation to some point and if it's outside in colder climate you may need to run a heat source which in my experience a fan will be needed to move the air around or it doesn't maintain temps very well. Unless you're using a heater with a fan in it already.

I did some sizing recently by taking to Corney Kegs to Home Depot.
  1. 5 CF 2 Kegs
  2. 7 CF 3 Kegs

I have a Keezer in the house that holds 6 (with a 20 lb CO2 tank) but I will have to go look up it's size.

I also have a chest freezer in my camp site (with the compressor cut out) that I use as a Ice Chest and it holds 4 (no---update--- it holds 5) I think it is a 8.8 CF
