Freezing Pipe

[foureigths]

Can a copper pipe with glycol water mix at -20F be frozen for repair with at ridgid pipe freezer?

I know that a 50% concentration of glycol and water will freeze at -37. I'm just not sure what the pipe freeze kit will get down to, I know dry ice is roughly -70 below that so i would guess the kit would be some where close to that. Rick I'm sure will have all the answers you will need when he gets on:D

liquid co2 is dry ice. it's -107f. that will work great as long as there's no flow.

i don't know the temperature of the ridgid super freezers? i do know that they are not as cold as the co2 units.

but they are a whole lot easier to use and set up.
