The Siesta Perfera ATXM25R / ARXM25R air conditioner from the Daikin company has a power of 9000 BTU and is suitable for spaces from 13m² to 18m². The Inverter technology it has makes the air conditioner initially work at maximum, until the set temperature is reached, and then it works minimally and continuously, keeping the temperature level in the room constant. This makes it more efficient combined with low consumption.
