Hmmm. CO2 'from the bottle' is a by-product of either combustion, fermentation (on a BIG scale like ethanol production) or a vent stream occurring naturally. In order to make the grade - it has to be pure to ppb levels of most contaminants (Hydrocarbons especially Benzene, Nitrous Oxide, Nitric...
Pretty sure all the jacketed fermenters I have seen (including my own) only have glycol circulating on the conical section. Usually the lower half of it. I think the internal agitation of fermentation must prevent stratification and the most economical way is to only do what you can get away...
"apart from the obvious bling factor, why does it have to have a conical base?"
For goodness sake Yob everyone on here knows you aren't a real brewer until you have a SS Conical.

I agree - the segment pot thing in my opinion is not required - I don't use mine anymore - just cold crash and filter. Clearly the cradle is required and yeah - the height looks a bit cumbersome.
I assume that these will be available in the US and Australia eventually so shipping shouldnt...
Indeed you are right
From the battering me and the other Williams Warn Fanboys have received I was a bit gunshy and a little tongue in cheek. Putting Williamswarn anywhere near the title would have started the whole thing off on the wrong foot.
For what it is - the title should be "50L Conical...
I haven't seen one in the flesh - but by the looks of the video I watched it is a 50L keg with a conical section replacing one of the dish ends.
The VPRv and pRV are identical to what is on the 30L WW. The lid is much smaller.
I can bet that the max pressure is 300kPa - given that 220kPa is ~...

I see a few drawbacks - the main one being the need to mount in a fridge with some form of lifting device.
But a 50L pressurised SS conical for ~ AUD1.1K - looks promising.

RPi/Arduino whatever pissy arse little gay microprocessor pieces of crap just suck. They aren't kids play - they are infuriating and flaky.
Buy a PLC and a touch screen HMI - will be robust, it will work, programming is done in a logical language not Swahili - sure they cost more to buy...
Definitely measured in the gas space.
Which given the height of the liquid column is < 1M would be very close to the pressure measured at the bottom of the sediment pot - probably 10 kPa different max.

There are 2 pressure control devices.
A simple spring balance type on the top of the unit that is adjusted by a 'thats where I set it last time' number of turns. Next to that is a pressure gauge.
After pitching I open 1.5 turns to the left - that gives ~180 to 200kPa of pressure...
Yep
I used to spend a grand a year on a new cricket bat and boots. Wouldn't think twice about spending 250 on a new squash racket. Don't get me started on Golf clubs.
Don't have any of that stuff any more.
Will have my shiny brew stuff for ever.
