A pre-chiller chiller - Page 2

Hot groundwater here, too, in SC (80F +) during the summer.
First use of my pre-chiller last weekend (built it last winter). Worked great, a 7lb bag of ice cooled my CFC nicely, and the output was pitching temps. Ice melted faster than anticipated, but it all worked. I'll try the salt option next time!

Put the rock salt in first and give it a good stir, add half of your ice, you will loose some pretty quick to the salt, then add the rest. Makes a ton of differance.

The chiller was a success.

I designed it exactly as explained earlier in the thread. Basically, the run was:

Garden hose, copper pre-chiller in bucket of ice water, ball valve, immersion chiller, and out to street. Obviously, there is nylon tubing, barbed fittings, etc., tied in to make the connections.

It worked even better than I hoped. Ground water was not too bad...about 76 degrees from the garden hose. I measured the outbound water after 15 minutes at 63 degrees. I had the entire kettle at pitching temp (65 degrees) 15 minutes after flame out. I am thinking about adding Jamil's whirlpool to the mix. I swear, that will be the last upgrade.

Yeah, good luck with that. A more accurate comment would be "I swear that will be my last upgrade for a couple of weeks."

Glad the pre-chiller worked out for you!
