Default Maxi 310 fermentation Chiller

Well now I have figured out how to conect a coil up to my maxi I decided I better make a copper coil for it especially since my fermenting beer reached 22c this morning. Not so much of a worry now that it is nearly a week in the fermenter but all the same.

So I made this



out of 10m of 10mm copper.

It is now attached to the chiller and busily keeping my fermenting beer down to 19.5c. The Maxi is attached to the cooling side of my temp controller so it just come on when it gets too warm.



Hopefully better controlled temps will result in more consistent brewing.

I now also plan on attaching a water feed through it to chill my water prior to going in the wort chiller on brew days. In winter it is fine the water is never much above freezing but in summer tap water temps rocket and the difference in temp between wort and chiller decreases making it difficult to get the wort down to pitching temp. Anyone tried this is it worth it.

Thats an excellent idea - I use an ATC-800 connected to a maxi cooler and a sumbersible heater to control fermentation temps but never thought of using the maxi to chill water going through the wort cooler.

Well you struggle with water temps in summer. I am just going to put some hose attachments on the other two pipes and get some more hose so the chiller can stay were it is. Obviously I will have to put a bypass (which it came with ) back onto the infow and outflow of the pump so that just recirculates back round.

FV idea is a good one. However DO NOT under ANY circumstances use a cooling loop through your maxi, you will break it. It isn't designed to cool at that temperature and likely you've just torch the compressor rendering it useless. If you meant using it to cool a barrel of water and then use that barrel to run through your wort chiller then of course that'd work fine, direct cooling though. A very expensive mistake.

I realise that . What I was meaning was to pass the flow of water from the hose through the other inlet and out let as you would beer, but obviously it would be under pressure from the tap and not pumped. It is just to get the temp of the water down in summer. i wouldn't be recirculating it.

For the most efficient heat exchange I'd only be using the Maxi line once you're down to say 35-40 deg c. Using it before then may actually be counter productive by increasing the temp of the coolant before you really need it, to give the biggest difference between wort and chiller.

I guess you took a break from picture framing during that build....

Strangely enough I`ve just finished my maxi cooler build, which also incorporates a small heater. Just need to connect it to the coil in the fermentor

Nice looking setup. Did you add the STC100? Mine has no built in temp controller.
