Swegon AUY 25-30-36-45AW is a cassette type air conditioner that can be used for cooling or heating. The main parts of the system are located outside and inside the room being cooled, which results in a more discreet design and less noise in the room. The outside unit is weather resistant and thus suited for outside placement. The round shape of the indoor unit allows for an even distribution of airflow throughout the cooled room. To control the airflow direction, there are adjustable louvers on the front of the indoor unit.
