Designed specifically to meet the needs of customers with larger rooms or heavy duty applications, this innovation from Koolbreeze incorporates a new energy efficient compressor and a tough body to ensure long life. This portable air conditioner is designed for larger rooms and offices where you require cooling or heating all year round. It can make your lounge or office cool and comfortable and thanks to its quiet operation, it won’t disturb your train of thought. This Portable Air Conditioner packs 16000btu of cooling (and 14500btu heating) power. This model is an air conditioner, heater, dehumidifier and fan. It is an energy efficient multi-season unit utilizing heat pump technology to extract heat from the air while consuming less energy than other portable units . Our evaporative technology uses any collected moisture to cool the unit before it is eliminated through the exhaust ducts leaving no water bucket to empty. Unit must be vented outside when in AC and heater modes. For the purposes of EU regulation EN12102 this is a “local air conditioner” and produces less than 65Dbl sound energy.
