Thanks for the alternative solution.

Does it really matter what kind of antifreeze I mix with the washer fluid? Probably cheaper for sure to go with the washer fluid. If I go that route I can afford to get the project under way tonight and be running it tomorrow.

How much more condensation is going to form when the chiller starts pumping -30c coolant? Will I get frost?
