The top 3 silver ones are dedicated to the 5500w elements for the HLT and BK's. The other 6 black ones are 2 x 4000w elements for the heat exchangers and 4 x pumps. I need to run SSR's with the BCS to run a fully automated system.
Well the 2 BK's are 150L each, but I will only fill them to around 135L for a 90min boil to produce 100L of wort each.
I will do a build post in once I have finished testing the various parts of the rig.
