Hi all! Cold-crashed for 1st time with my homemade glycol-chiller & spike cooling coil (set up in a CF10), and ended up with a big ice ball around the cooling coil. My made with an igloo cooler & a window AC unit, so I can’t set the temperature (dials are gone). Don’t know my glycol:water, as...

Sure has, thanks! 🙂

Think I’ll start doing this. Better than forking over $20 in CO2 for a leak, eh?

Dang! Thank you all for the feedback, and some of the best/funniest back-and-forth banter I've seen in a long time 🤣 So, here it is. It was the lack of gas pressure to create the seal. Never ran into this before, but there it is. Thanks again, all! I'm going to keep that pennies under the bail...

That's exactly what happened, pvpeacock!

Good question! CIP Keg Lube

Absolutely! Going to test out these ideas this afternoon, and results will be posted 👍

Good point sibelman! However, it did this as I held it up to ensure the leak was coming from the mouth and not one of the posts. I’m guessing it’s the lack of pressure, which I’m going to test

Cheers, mate! This post is turning out to be a real education 🤣

cheers! What are bail legs?

Great point about pressure being needed!

whats mol weight? Sorry I don’t know a lot of these numbers/words 😄

Hey, bracconiere! Not entirely sure but probably around 15psi. Not coming out the pressure release valve on lid

Hey all, Bought a pin-lock keg from a very reputable online store, purged CO2 it came with, & filled it with StarSan. After letting it sit for a few, I tipped it on its head to sanitize the top and, to my surprise, StarSan slowly leaked out of the mouth seal! Wondering how a keg that held CO2...

My favorite beer doesn't exist yet :cool:

Cheers!

Thank you all, so much, for your ideas. This was extremely helpful. In the end, I added more glycol to the mix and it seems to have worked. Before, the window-ac unit I used to build my chiller was running non-stop. Now the ice-jam on the evaporating coil is gone and its MUCH more efficient...

Woah! That's super interesting! I'm going to switch them around when I get home. Thanks!

Great idea on the 1/2" insulation. I'm going to give that a go! I haven't changed the flow between fermenting temp and cold crashing. I just have an aquarium pump in my Igloo cooler, so not sure how to do that.

Thanks, Golddigge! Can’t remember the ratio, but should’ve been good for quite cold temps. Obvs not good enough, eh? I’m going to buy more and fill it up a bit more. I followed Spike’s recommendation and am setting it to 38F. Hopefully it all comes out right in the wash.
