Default Another cooling package engineer designing a chiller

So a friend of mine and I were looking at the wort chillers and thought 30 min was a long time to cool it off (we cool off 1000 lb-ft desil engines with 100 degree air in no time). So... we designed and built this. It cools 5 gallon boils down to ~60 in just under 7 minutes. Not sure if that is good for the beer or not but it sure causes a lot of junk to drop out of solution and so far the beers have been good that I've used it with.

What I started with:

Coils:

I wove solid copper wire and soldered the joints to make it stiffer... worked like a charm. After a couple boiling water baths to get it clean we were in business!

Looks good!

I take it that you have one water input, and dual outputs?

that is correct, the inlet splits right at the "water" line

I like it! How many feet of tubing did you use 50? Any more projects in the works?

yes it has 50' of 3/8"

I've been working on labels and the brewery logo, soon to become a lighted acrylic sign... assuming that works as planned I'll post pics of that build also.

I have been working on the mancave/ brewery quite a bit this summer... we just realized that we didnt take before pictures... maybe ill show a partial transformation on that one when its done.

there is always projects that need to get done... but thats what the homebrew is for!

Was that done to increase the dwell time of your cooling water in the wort, or was it a by product of the parts you had on hand?

Nice neat work area, looks much cleaner than mine!

From what you are saying this is a HUGE jump in efficiency over the standard copper wort chiller! What I am not grasping however is from your second picture how you invert the smallest coil to fit within the medium coil?

Dwell time and pressure were increased with pinch clamps on the outlet hoses, they start open to help bleed out any air that is in the cooler, then i pinch them down to keep the outlet water warm until the end when they are almost closed. Not very high tech but it works.

the inner coil is cut off of the medium coil and shifted down then I soldered them back together with a union.

You don't just keep the water full blast the whole time? Is that just because you don't want to waste water? The reason I ask is because I use my outlet water to cool the outside of the kettle as well..set it in a tub that is slightly shorter than the kettle.
