I use a Lindr AS-80 for my cooling water.
It is beer line chiller, and costs about half of what most glycol chillers cost.
I usually keep it at 2 degrees, so I don’t need glycol. Glycol is a pain when you spill it and water works just fine.
Two 12v pumps pump cold water through the coil in my conical and my brite tank.
We made these boards to be a drop in replacement for the Ss Brewtrech FTSS (in combination with a Spark).
They can switch the pump and the heating mat.
For my conical and it takes about 10s of pumping every 10 minutes to maintain a steady temp. More when cold crashing of course. Cooling with liquid is very powerful. Temp controllers like the inkbird don’t work well because they turn on for too long before the measurement registers a temperature drop.
As an added bonus, this chiller has 2 or 4 coils to cool my tap lines. That what it was designed for.
It has an integrated python pump, which is used to pump cool water around the beer lines going to the taps. I later made a bracket to hold the python:
The python just has a U fitting at the taps to return the cold water:
It really doesn’t matter I think. Your glycol/water chiller provides cool water. Brewblox just controls the small pump that uses a bit of that cooling water.
