Cold Crashing in an Anvil King Junior

[mattman91]

Does anyone have a suggestion for cold crashing in an Anvil King Junior, or any similar type of plastic pressure fermenter?

I’ve tried it once, and because a dunce, I didn’t realize the temperature change would cause it to dent inwards. It didn’t do any permanent damage, but I know it can’t be good for them.

Would applying pressure to it prior to crashing help? Would it need to be connected to C02 the entire time?

Thanks!

The fermenter sucked in due to the cold. Look for " cold crash guardian "
