The Daitsu Atlas AUD12KDB is a premium 12000 BTU commercial-grade ceiling cassette split system engineered for discreet installation within standard suspended ceiling grids. Delivering 360-degree radial air distribution, this unit eliminates cold draughts and establishes uniform temperatures throughout modern retail outlets, offices, and open residential layouts. Utilizing R32 refrigerant paired with a heavy-duty inverter compressor, the Atlas cassette achieves high energy efficiency alongside powerful heating and cooling performance. The built-in condensate lift pump facilitates clean, flexible drainage installation. Controlled via a backlit infrared remote or an optional wired controller, this cassette split provides quiet, continuous air circulation while leaving floor and wall surfaces entirely unobstructed.
