How much water do the coolers consume?

The rate of evaporation depends on the relative humidity of the air. The water reservoir in our coolers are designed to operate for between 3 to 6 hours without refilling. The larger coolers used outdoors have continuous water need with float valve for shutoff. The following table lists the reservoir size, estimated water usage, and time  between fills.
