This 13,000btu, 3-in-1 system provides multi-season comfort. Designed to efficiently cool and dehumidify any space without permanent installation. Effectively improves air circulation in poorly ventilated spaces and provides fast cooling. Self-Evaporating Technology - during the cooling process, water is extracted from the air into the unit. Most of this water is recycled and used to cool the cooling coils. This creates improved cooling efficiently without adding energy cost. The moisture is then pushed out with the exhaust air, leaving you a virtually no-drain unit. In extreme humid conditions, if condensation collects faster than the unit can evaporate, the excess water will collect in the built-in tank. When the tank becomes full, compressor will automatically shut-off and unit will indicate that drainage is needed. Note: Exhaust hose installation required (all standard accessories included). Included plastic slider kit forms up to 48".
