A spot cooler works just like the air conditioner in your home: it cools air by running it over coils containing a chilled refrigerant. The refrigerant is then run to a compressor, which compresses it to a
hot liquid inside a coil. A fan blows over the hot coil to exhaust warm air. The refrigerant is then decompressed, which chills its temperature again and allows it to cool your room. In your home, the compressor is placed outside the house. In a spot cooler, the compressor is inside the spot cooler itself and the warm air is discharged through a tube or duct. The duct can be run outside of the building, or in many cases, it can vent into a drop ceiling to get the warm air out of your room. As the spot cooler chills the air, it will also remove moisture from it. The moisture will accumulate in a condensation tank that you will need to drain periodically. Our spot coolers feature digital controls that make it easy to set the temperature and blower speed.
