Here is proof if proof was needed that I need locking up.
This coil array sits in my 20 gallon stainless brewpot and displaces about 1 gallon. Each coil is individually fed with mains cooling water. There are fittings in the 10 mm thick perspex lid for two 4.5kW heatstick style elements and a centrally placed motor driven stirring arm to promote a continual circulation past the elements during boil and the cooling coil during er..cooling. The plan is to have everything entering the vessel from above, no taps etc etc.
Each coil is held in space and does not touch any of it's neighbours. You can even hold it at this angle and shake it without them rattling together. For this intermingling style to work, there has to be an even number of coils and alternate coils have to be left hand and right hand wound. This example has 6 coils.
After making a winding former out of foam blocks, individual lengths of copper tube were filled with sand, and wound around the formers using the lawn as the workbench. Holes were drilled in the perspex lid and the coils were arranged in a neat bunch and slipped into "cable gland" style clamps in the lid. The clamps grasp the coils with enough force to hold them firmly in place. A pair of copper manifolds manage the water flow, and if I was to do this again I would have them on the central axis and integrated rather than separate as in the photo's. I was keeping hot and cold separate and that means each yellow hose pipe length is different!!
I do not have the figures to hand, but it cools the entire boil quickly and then I will let the plate cooler take over as the beer is transferred to the as yet to be built fermenter.
All mickey taking is expected to be supported by documented evidence that this is not the way to do it, unless your ******, in which case you are forgiven....
