Designed to fit smaller to average-size rooms, the Alen C360 delivers 9000 BTUs and cools up to 350 square feet offering superb performance at a great price. The C360 also functions as a dehumidifier with an inner water tank and two options for emptying - a built-in water pump or drainage through a traditional water pipe. With the water pump feature, when the inner tank fills, the unit will automatically pump the water out of the unit. Included with the C360 are both a window and a wall exhaust kit. The kit enables the unit to exhaust the hot air through either the window or the wall.
