Hope that this answer yours questions!
If a have gone for only 1pc crane then a have put 1pc of this mix valve after the crane so a can easy mix/control my reflux cooler with this mix valve.. but to start with a go for 2pc crane ( 1pc to reflux cooler and 1pc to dump.. and a can always plug 1pc crane and put in 1pc of this mix valve if a need to control my reflux cooler more exact later.. but remember that a have 3pc 5500watts element and 300-400liter of mash and 8” size in column…
Don’t forget that a must have ATEX/EX on all my electric parts… and the price for same stuff that are ATEX/EX classified is about 10-20 time more expensive than Note classified electric stuff.. so a go manually ….. and only have ATEX/EX classified electric heaters and safety valve…
I also have 1pc thermometer in the bottom/end of this product cooler after the “water cooling part” so a can read what the temp is on the alcohol/licuid before it go in to my parrot …

It is 8pc copper pipe about 65cm long 15mm ( outside dimension) copper pipe in this 4” product coolers cooling part and a have also same “copper sheet- end sheet” with 8pc 15mm hole in them spaced about 10-12cm apart with about 10mm of one corner cut away ( one to the left and next to the right) so the cooling water always must zig- zag around all copper pipe from the bottom to the top for maximum heating/cooling change…
And a shall also made 2pc in 4” ss but there a need to have about 15pc 15mm ss pipe and about 100cm long to have the same cooler/heat change when it is in ss….
Some people want ss in the product cooler and pipe after the reflux cooler, so a made it so the don’t get sorry….
