While in a "typical" situation where your ambient room temp is 80 degrees F and you are trying to keep an ale at say 68 degrees a small marine cooler/ice box full of ice water might last for 24-30 hours without needing to add any ice to keep the water cool, when doing very aggressive chilling regimes like crashing or lagering, then you are limited by the chill water source. Some caution is needed if you have a one way airlock as cold crashing will result in negative pressure in the fermenter and can suck liquid from the airlock into your fermenter.

Each beer was fermented with a lager strain and to prevent premature yeast flocculation, agitation was applied at 100 rmp. Then they cold crash for 3-10 days.
