The most crucial component is the freezer box which has the refrigerant, air filter, control panel with a display, exhaust, power cable, and a drain line. The freezer box is responsible for condensing the moisture in the air into liquid water. You have to plug the dehumidifier’s power cable into the mains electricity supply before switching it on. The power button is often on the control panel.

Once the commercial dehumidifier is powered on, the display will turn on and show your current relative humidity. Relative humidity is typically represented as a percentage. Use the UP or Down buttons on the control panel to set your target relative humidity. For instance, if your current relative humidity is 57%, you can set your target relative humidity to 25%. If the dehumidifier is working okay, you can feel the area around the air intake getting cold and the exhaust area getting hot. Remember to turn off the dehumidifier before unplugging it from the mains electricity supply.
