I have a 1/3 HP Penguin glycol chiller and was wondering if there is any reason to keep it running when not in use. I have been just because of the concern that mold or mildew could potentially grow in the reservoir if not kept near or below freezing, but I’m not even sure if a distilled water and glycol mix would promote mold or mildew growth. Also not sure if there any kind of adverse effects that big temperature swings could have on the longevity of the solution.
Any thoughts?
