It'll work as long as the OP doesn't expect to put too much volume through
it.
I was not thinking of flash cooling. I assumed that the coil would be of
some length, say 25 feet, plenty of time to cool a reasonable amount of
soda water. A 5 gallon bucket of refrigerated water represents a heat sink
to be reckoned with, given enough surface area.
Of course, the best method for the op would be to invest in soda kegs and a
refrigerator so he could batch carbonate. I have a commercial carbonator,
and realized quickly that it was serious overkill. But trying to tell a man
with a mission he's on the wrong track is like ****ing on a house fire...
