I can get it at my local hardware store But I am not sure about all the fittings. It doesent cost that much more than the soft copper. Nice build Bobby

Got $200 in gift cerftificates for Xmas & birthday. I would have liked to built one, but with my work schedule, I have a limited amout of time ( put in 60 hrs. last week, truckings sucks). I will post pictures if I get it and if I can figure out how to post pictures. I am trying to get all equipment ready for all grain brewing once weather breaks in the east.
using the convoluted in my opnion would be a superior build (IMO)and from what B3 sells its like only12 feet or less from what I can see on there sight. but for the cost the 70 dollar one looks like a screemen deal.mrkristofo said:How's the efficiency of this thing? A couple things i've been pondering, Bobby, are 1. Using convoluted copper tubing (turns out it's really expensive), or 2. wrapping the inner copper with wire so that it creates more turbulence in the water, and thus cools the wort quicker. Maybe it's not worth the extra effort if it works fine already, but just a thought. It could end up shortening the overall length of coil required.
yes.. I do back to back 12-14 gallon batches at the end of my first boil I would be using the water from CFC to run into my HLT for sparging batch 2Bobby_M said:Well I've used that braid reinforced stuff for hot wort transfer hoses so if it leached anything, I sure didn't know about it. I think they're technically good for up to 180F and it never really gets that hot. I don't see any problem with it. You doing back to back batches where you'd need more water after chilling?
that would be killer my system can take 12 gallons of 55 deg water to 190 in 30 min or less so starting at even 100 deg F will sure save me some $$$Bobby_M said:I never put a thermo on the coolant but I know it's "warm" to the touch. If I had to take a guess, I'd say 110-120F based on how fast I run it.
ClutchDude said:I went to Coppertubingsales.com. Since I was getting 50 ft, here's my plan:
I'll double up a 1/4" copper. You can drill a compression coupling to allow a pass through. I think the major problem will be getting one of the copper lines through a T fitting, though. A "Y" coupler would work best, but I haven seen any at the store.
Anyways, this would deliver a high flow rate than 3/8" and more cooling due to the increased surface area(roughly 1.3x). The hosing should provide enough space to pull this off as well, I imagine.
Bobby_M said:I hate to tell you this but a single 3/8" OD tube has nearly 3x the cross sectional area as two 1/4" OD tubes. That doesn't take into account any added drag.
That is the beauty of a CFC with a pump, it will cool the wort and fill the fermenter(s) as quickly as the pump will push it. In my case, about 3-4 GPM, or for a 25 gallon batch, 6-7 minutes. That's better than most people can cool a 5 gallon batch with an ice water recirculated immersion chiller.:rockin:sleepystevenson said:I assume that this length of CFC would work for larger batches, as well? (seeing that the amount of wort being cooled at one time is the same no matter how large the total batch is.) I am working on a single level one barrel system now (similar to the brutus ten type) and am looking for the most efficient (and cost efficient) chilling method. The Therminator sure looks nice, but the $200 price tag sure doesnt....
Bobby_M said:I think 25' is borderline overkill and I'm positive 50' would be. Make two, sell one.
Bobby_M said:Think about all that wort inside the tube. Not a problem if you gravity feed but pumping will leave like a gallon inside the 50' tubing.
Bobby_M said:I'm like a broken record about it around here but prechillers are a waste of copper. If you're already commiting to having a container of icewater laying around, pump it into the CFC directly. Prechillers, especially a 15' one, will only drop your coolant water down a few degrees.
If you make an extra CFC and sell it, you can take that money and buy a decent submerssible pump. Just IMHO.
Bobby_M said:I'm not saying I'm an authority on chilling by any means, I just tried using my old IC as a prechiller once and had less than stellar results and after bumping this theory up against a bunch of other people here, they found similar things and converted to icewater pumping.
