How long at -40 for dewax

Normally when dewaxing I leave my containter in my lab freezer -40 overnight. I’m in a hurry to complete a run in time for a customer and need to know how soon after my ethonal oil mix reaches -40 can I run in through my filter step?

12 hours at least, you might need to do a few cycles of freeing/filtering.
