Default Will a pressurized keg freeze

I want to put a kegerator in my garage. However, I'm afraid the beer will freeze (it's winter where I live right now). I've had crappy canned beer freeze on me in the fridge I want to use from time to time. I was just wondering if the fact that the beer would be under constant pressure would mean it wouldn't freeze? Any thoughts?

It will definitely freeze. The pressure we work with isn't going to affect the transition temperatures of the beer in any measurable way. Think about it- the beer in the cans was under constant pressure too.

I believe the increased pressure in a keg will have minimal impact on the chance of your beer in a keg freezing:

"It is also true that pressure changes the melting temperature. However, because the volume occupied by a kilogram of liquid is not much different from that occupied by a kilogram of solid, this effect is very small unless the pressures are very large. For most substances, the freezing point rises, though only very slightly, with increased pressure."
From: http://www.animations.physics.unsw.e...-elevation.htm

In other words, may your beer freeze? Yes, it might. Just depends on the temperature...

Welcome to HBT! Lots of great people and information here. Beer that is in a keg will freeze just the same as beer in a bottle. Many people put a small light or heater in their kegerator during the winter months.

Any ideas on what type of light or heater I could get for that? Something that has some sort of temperature control I assume?

Oh, it'll freeze. I've frozen many. The freezing point is under water, but not that much.

Here in Florida, we won't have that problem in our garage. But we do have that problem when we clean our keezer and forget to toss the temp sensor back into the keezer when we're done.

I use a Lasko MyHeat that has been modified to run the fan constantly when turned on and the heater element is controlled via a BCS-460 using PID. In the past I used a 15 watt light bulb wired to a Love TSS2. There are also commercially available temperature controllers sold by brewing supply companies. Do a quick search for "temperature control" in the DIY section here at HBT and I am sure you will find a solution that works for you.

A small ceramic heater with a thermostat would be perfect. Like this one for $19. Like many others, I have a much more complex setup, but I like complex

What if it was in a refrigerator and it was turned off and the refrigerator was left outside, or in an unheated garage in below freezing temperatures?

The fridge is in a garage, it still get's cold enough to freeze. Passedpawn, what's your setup?
