that is an absolutely excellent point. i only had 1 chiller that was an open tank and that was a long time ago.

i do not have any chillers that have a design evaporating temperature colder than the solution freeze point...that would be dumb and counter productive. i have run across systems that were improperly maintained and had an evaporating temperature lower than the solution freeze point (due to low flow rates) and they did occasionally make slush...but i believe that it was a solution slush, not a water slush and the glycol still a fluid.
