From repurposing an air conditioner to using a temperature controller and a humble light bulb to trick the system, the build is all about thinking outside the box and making sure my beer stays in that perfect fermentation temperature zone. But keeping the glycol chilled is only half the battle. Here in Part 2, let me show you how I circulate that cold glycol to maintain the ideal fermentation temperatures and make sure everything stays on track during the hot months. Let's get that cold fluid where it really counts. Now that we’ve got a reliable reservoir of sub-zero glycol humming along in our Igloo cooler, it’s time to move that cold power where it counts: the fermenters.
