Midea MCA3-18HRN1-Q / MOU-18HN1-Q is a ceiling cassette air-conditioning system designed for offices, retail spaces, restaurants, hotels and other commercial environments. The main indoor chassis is concealed above a suspended ceiling, leaving only the decorative panel visible inside the room.

One of the key characteristics of the MCA3 design is its 360° airflow distribution. The circular airflow arrangement and corner outlets help distribute conditioned air in multiple directions, making the cassette format especially useful in open office and commercial layouts. The system delivers 18,000 BTU/h of cooling and 19,000 BTU/h of heating and uses an On/Off compressor rather than inverter control.

An integrated condensate pump provides a lifting height of up to 500 mm, giving installers greater flexibility when routing drainage above a suspended ceiling. An optional KJR-90A wired controller can also be connected, while provision is available for connecting an additional supply-air duct at the corner of the indoor chassis.

The MOU-18HN1-Q is a universal Midea On/Off outdoor unit designed for compatibility with cassette, ducted and ceiling-floor indoor units.

At Euroclima, the Midea MCA3-18HRN1-Q / MOU-18HN1-Q is a practical commercial cassette solution combining concealed ceiling installation, wide airflow distribution and reliable cooling and heating performance.
