Can't answer your question but I thought I'd raise a few other questions.
Do you then plan to pitch in it? There will be a lot of cold break material.
Can you crash in one? The temp drop from post boil temps to pitching temps is even greater than the drop from ferm temps to crash temps. Meaning there will be quite a bit of negative pressure, or air lock suck.
I am ordering the SS Chronical, and have been researching those products. According to them, you totally can use it as a chiller with the temp. control system. The cold break should settle to the bottom of the cone on the brew bucket, there is a valve to release yeast and solids settling at the bottom.
