Product Description
Midea Multisplit Inverter Outdoor Unit M5O-42FN8-Q 12.3 kW for 1-5 Indoor Units / Wall Units
MIDEA multi-split inverter with 12.3 kW rated power
The MIDEA multi-split system allows the operation of multiple indoor units with a single outdoor unit. The exterior casing features an elegant, diamond-cut design that offers both stability and an attractive appearance, ensuring safe operation and a long service life. The "Archimedean" screw-shaped air outlet and the bionic fan impeller minimize noise.
The stepless frequency adjustment of the compressor and motor ensures a constant room temperature and avoids energy-intensive stop-and-go operation, which both reduces costs and extends the service life of the air conditioner.
Individual air conditioning solutions for 1 or 5 indoor units
This unit offers versatile climate solutions. With its heat pump function and operating range down to -15°C outside temperature, energy-efficient heating is also possible. You can connect up to two individually controllable indoor units to create an optimal comfortable climate in different rooms. You can choose from various indoor units: wall-mounted units, ceiling cassette units, floor-standing units, and ducted units.
