So my brew buddy and I have been trying to figure out a way to keep our conical temps regulated during these hot NC summers. Here is our solution.
Our solution, a SS coil with camlock fittings.
Camlock and bulkheads from StainlessBrewing.com.
Our full solution. Cooler contains ice water with a small pond pump recirculating through SS coil inside.
Our homemade temp controller per the aquarium temp controller build thread on this forum.
As of two days later, its maintaining our target temp of 63 F. Ambient temps have been in the high 70's low 80's.
