I am talking with them about this option.
Under my ferm fridge, I have a 3 drawer freezer. Why not just put a glycol reservoir in there? What’s so special about glycol chillers? The freezer has its own compressor, so I can even control the glycol temp.
Why not let the glycol warm up deliberately? Give it less capacity on purpose? It will be cooled down again by the freezer, but this will take time. Or set the glycol temp to just 5 degrees under the beer, so you won’t cool so damn quickly.
