Glycol chiller question

3 points · submitted Aug 2019 by u/HeyGuysImJesus

The claim on the website says it can lager with their fermenters. I tried mine out for the first time and tried getting water down to lagering temps. It worked great but the chiller did run a lot and the fermenter had trouble holding the lower temp for longer than 15 minutes and would take just as long to cool it back down. The reservoir is set at 25F but when chilling, the glycol temp would increase to about 40 and take a while to bring it back down again.

How many fermenters could the chiller handle if set at a fermentation temp of 50F?

Would setting the glycol temp lower than 25F be a good idea?

Do you think the fermenter jacket would help even though the fermenter is double walled?

So turns out that setting the glycol to 7F will turn the contents of the fermenter into slush. Even though the bottom reads in the 40s. All the ice floats to the top. I think I'll just leave it at the recommendation of 15F below the fermenter setpoint. It works for what I want. I do plan on picking up another fermenter so I'll see how it goes with two lagering.
