4-in-1 Air Conditioner with WiFi Midea Breezeless E 2.5 kW (3) + 3.5 kW

The Midea Breezeless E 4×1 WiFi 2.5 kW (×3) + 3.5 kW air conditioner is a high-performance, elegantly designed multi-split system, specially designed to cool four rooms of different sizes. The set includes three indoor units MCB1‑09N8 (2.5 kW each), one indoor unit MCB1‑12N8 (3.5 kW), one outdoor multisplit unit M4O‑36N8 (10.5 kW total), and four remote controls, allowing individual control in each room.

Thanks to Midea’s “breezeless” technology, the indoor units feature a micro-perforated diffuser that disperses air very gently, avoiding direct drafts and providing even thermal comfort. In addition, the system features integrated WiFi, allowing you to manage and program each unit via the Midea Link app from anywhere.

With a total cooling capacity of approximately 11 kW (equivalent to 37,500 BTU), this system is ideal for large homes, vacation rentals, or facilities with multiple rooms. The inverter technology ensures efficient, quiet operation tailored to the thermal needs of each space, optimizing energy consumption.
