Large Water Reservoirs
Initially portable evaporative coolers required a constant water source, like a garden hose, to keep fresh water flowing into the cooler. But in situations where a water supply is not available, and a cooler needs to be manually filled, disconnected from the hose and then run, you have to buy an external water tank that you’d fill up and then connect to the cooler.
The external tank will be an extra cost and by incorporating larger internal water reservoirs into a portable evaporative cooler means you do not require a tank. This allows you, if needed, to fill the cooler, roll it to where you need it and then let it run all day.
How is COOL-SPACE different?
COOL-SPACE units have large built-in water reservoirs which allow for hours of operation without a water source (hose).
