SPLIT cassette air conditioners
Cassette units
The outdoor units are equipped with base heaters that enable efficient heating operation even in extremely cold outdoor conditions. The air conditioner activates the defrost mode only when necessary and only as much as required to defrost the heat exchanger, ensuring nearly uninterrupted heating. AUX air conditioners use an intelligent defrost system that improves energy efficiency by 5% and increases heating performance by up to 20% at low outdoor temperatures. The built-in high-pressure drainage pump can lift condensate water up to a height of 1200 mm.
Efficient Compressor Operation
The DC inverter compressor utilizes 180° sine wave control. This technology ensures smooth operation of the compressor motor, significantly enhancing the unit's efficiency.
Automatic Restart with Memory Function
In the event of a power outage, the unit remembers the last settings and automatically resumes operation with the previously set mode once power is restored.
Thanks to the specially designed decorative panel, the AUX cassette air conditioner can cool every corner of the room, providing maximum comfort to all users. Additional air supply vents in the corners of the panel allow air distribution in all directions, eliminating zones with uneven temperature distribution. The perimeter air supply technology ensures 360° airflow, guaranteeing effective air conditioning even in large spaces.
Fresh Air Intake
The cassette unit's housing features a factory-cut opening for fresh air intake, allowing the unit to supply fresh air from outside into the room. The maximum fresh air intake can reach up to 10% of the total supplied airflow.
