Optimal Glycol temperature for SS Chronical cold chrashing

[KimJohansen]

Hi there,

What temperature do you set your glycol to when chilling for cold crashing your SS Chronicals? In my latest batch I went down to 10F only to realize I got ice around the chilling coils.

I'm having trouble getting my ½ BBL fermenters reaching 30F. For the most part I settle with 35F.

So what's the optimal Glycol temp for reaching 30F?

Actually the optimal temp is 28 degrees. Anything less than that and you will experience icing. The problem with ice forming on your coil is that it acts as an insulator, and will actually hurt the performance of your chiller, preventing you from crashing below the high 30 degree range. Stick to 28 degrees, virtually every commercial brewery would agree!

We have an FAQ on that here:

Thanks Michael,

What threshold temperature for the Glycol would you set as upper limit before the Chiller kicks in again?

Cheers,
