The Mitsubishi Electric MSZ-AY25VGK indoor unit is designed specifically for multi-split configurations — it can be connected to an MXZ series outdoor unit and operate in a system with several indoor units. This allows independent temperature control in each room with one outdoor unit. This model offers a nominal power of 2.5 kW (9,000 BTU) in cooling and 3.2 kW (10,900 BTU) in heating. Thanks to inverter technology and R-32 refrigerant, the device provides high energy efficiency and economical operation. The seasonal efficiency coefficients are SEER 8.7 and SCOP 4.8, which guarantees low energy consumption and stable operation throughout the year. The MSZ-AY25VGK is distinguished by an extremely low noise level — only 19 dB at the minimum level, which provides a quiet and pleasant atmosphere. It is equipped with a V-Blocking antiviral filter that effectively neutralizes viruses, bacteria and dust particles, as well as a self-cleaning function of the heat exchanger. The built-in Wi-Fi module allows control via the MELCloud app, which provides convenience and full remote control. Combining modern design, compact dimensions and smart features, the MSZ-AY25VGK is a reliable indoor unit for a multi-split system, providing efficiency, comfort and clean air in every home.
