| Description |
This auto shutoff can save your portable cooling unit from being damaged if the water level runs low. Evaporative coolers can be run for long periods of time without refilling, so it can be easy to overlook the water level. This auto shutoff will act as an insurance policy against expensive repairs if the tank runs dry. Many users choose this upgrade for outdoor event cooling, theme park cooling, and auto mall cooling uses, where busy employees can sometimes forget to check water levels. They work well for greenhouse humidification as well, where the units are often left unattended to do their work. The switch will arrive preinstalled on your unit if you choose this upgrade. |
