As I alluded to in the epic dragged out saga that is the Saison I brewed 3 weeks ago, I don’t have temp control on my SS Brewtech Chronical at the moment.
These SS Brewtech’s are awesome, especially for the price, they have a bunch of features that just aren’t available in some of the even more expensive brands (i.e. Blichmann). SS Brewtech offer a cooling option for these fermentors, but unfortunately I am not a fan of it, plus it doesn’t appear that it will work with the CIP/SIP capable 3″ tri-clover lid which is available shortly.
It is a small pump, a temp controller, and a stainless steel loop which hangs down (for the 17G anyway) from the lid of the fermentor into the wort. The temp controller switches on a pump when the wort is too warm, circulating cool water from an esky through the loop to cool the wort.
I dislike this solution. I do not want to be a slave to an esky full of cold water as it won’t stay cold enough for long enough. I don’t want to have to clean the cooling loop itself, as it will get krausen stuck to it. Also, unless it’s been updated recently it doesn’t work with the CIP/SIP lid that I am going to move to when available in Australia.
The intention is to have these machined by a hopefully local CNC workshop and then install these to the outside of the conical on the lowest part of the upper cylinder. I was planning on getting a number of the blocks machined as I’m not sure how well they will work – but the MoreBeer one sounds like it works pretty well with 4 peltier chips. Not sure of the size of the peltier chips or the blocks on the MoreBeer ultimate conicals.
So, as I’m intending though, it’s turning out to be a little tricky. As it’s a pretty small job, and I don’t want to spend thousands to buy a couple hundred items of something I don’t know if it will work or not, I’m struggling to find a local place that will machine it for me.
I’ve sent emails requesting quotes to a number of CNC workshops. It seems like the job is too small for most. The one and only quote I got back was $604/ea for 4!
I’m trying to keep this local, trying to get it done here, but it doesn’t look like I can afford it. I’ve asked for a favour from my old man who has some contacts, hopefully that will come off…
I’m not sure how I will heat the conical as yet. The SS Brewtech heater might be an option. It’s not too expensive, and it should do the job. Hopefully it doesn’t get too warm and cause autolysis though!
