General Homebrew Discussion / Heat Transfer / Copper help needed for a CF Chiller - Input needed

« on: January 21, 2010, 09:16:42 PM »

So I've decided to build a copper CF chiller.


I have a 50' roll of 1/2" tubing and a 50' roll of 7/8", but now that I have these I'm worried that it would be as efficient as the commercial copper CF chillers that use convoluted copper. 

What are your thoughts on making a 50' CF and can anyone tell me how quickly it could theoretically cool boiling wort?

Thanks for the ideas.  I thought about an epoxy because of it would fill the void and be strong enough to hold the pressure from the strike water but I wasn't sure if it would leech chemicals in the water and leave an off flavor.  I also thought about filling it either with all silicone or a combination of 1/2 epoxy on the outside to serve as a plug and fill the remaining, interior portion of the hole w/ food grade silicone.  My only worry is that this may not be strong enough and w/ the pressure of the water pop the plug.


Though not pretty I think the stopper/bolt combo might be the best.  If you have any other thoughts I'm happy to listen.


Thanks!

So over the weekend I decided to add a thermosight to my HLT.

In drilling my 3/8" hole I managed to drill next to 1 of only 2 bubbles/waves on the internal wall (warped from the heat of past brews). Because of its location I am unable to get the o-ring, washer, & nut assembly on.

I'd like to patch and re-drill a new hole. Does anyone have any suggestions on what/how to patch the 3/8" hole? It needs to be stable to the heat and pressure of 10g of strike water.
