Cold crash temperature - presure - clarity

[Mastoras007]

So I'm testing my glycol system last 10 days
I have filled the bbt 1000liters of water output temprerure 35 by day 18 by nights inside the brewer it's an average of 27-28 Celsius

I want my chiller to work not at maximum so I'm thinking what will happen if I cold crash at 5 or 6 Celsius..
At those temperatures is everything working so smooth...
Also at 2 working smoothly but I think the power consumption from 5 to 2 is to big,
Anyway have anyone try to cold crash at 5-6 C?
What should I use or not for clarity?
I'm not planning to use any clarity chemicals but if I do what's your suggestion?
Any trick to work everything at those temperatures?

Beer will be blonde ale with US-05

You really want to get beer down to at least 40F or colder. If your glycol is only 40F, you won't get it down below 45-50F. You need a 15-20F delta.

Also crashing slowly has always worked better for me. Crash too fast and the coil will freeze up.

I try to crash (slowly, max rate of 8°F/12 hours) down to about 30–31℉ and hold for 3–4 days for maximum clarity. You don't need fining agents to do so as temp will be sufficient, but I usually throw in 6g of wort-hydrated Irish Moss per 5gal with 20min left in the boil. I've never used post-boil finings and everyone I know who does, while skipping the boil finings, struggles with cloudy beer for a month. But I suspect that may be due to other factors. (they don't boil hard enough, or always hit a sufficient Calcium level)

No need to worry about the beer freezing. That won't happen until about 27℉ due to the alcohol present.

You should insulate the tank to save electricity. Then perhaps 2C is ok. But 5C can be ok too : you have to try it for your equipment

I suggest using “Irish moss” (or “Whirlfloc”) for clearing, as this is just a fine powder of some plant, not really a chemical. It causes the hazy things to clump together and fall more easily to the bottom of the vessel. It is added near the end of the boil.
