This is a bunch of unrelated stuff all connected together for initial cleaning/testing. That’s a March 809 pump at the bottom. It’s temporarily bolted to the three tier stand, though with the pump I won’t need that stand any more. Just wanted to test it and run some pbw through it. It is fed by the mash/lauter tun and is here running the “mash” (pbw) through my old immersion wort chiller, which is temporarily hanging inside the hot liquor tank. It will be used as a HERMS hex until the new, dedicated SS HERMS coil gets mounted in there. Then the “wort” goes through the counterflow wort chiller, which doesn’t belong anywhere in that fluid chain but I figured I may as well clean it while I’m circulating pbw. Then back into the MLT to be recirculated. The counterflow chiller will be removed but the rest will be used as a test bed tomorrow to see how effective the HERMS is at controlling mash temps while I brew a robust porter (and, if time permits,. also a holiday spice ale). The plan is to combine this hardware with a new one or two tier stand with temperature-controlled burners. I’ll switch out that cooler MLT for a kettle MLT at that time. I’m just trying to keep this old rig operational as long as I can while working on the next gen rig.
