Air conditioner (heat pump) Mitsubishi SRK-SRC25ZTX-WA Kazan Arctic series

The Mitsubishi Heavy Industries Kazan Arctic 25ZTX-WA is a high-efficiency inverter air-to-air heat pump designed to provide reliable year-round indoor comfort. It delivers efficient cooling during the summer and powerful, dependable heating during the cold winter season.

The system combines advanced Mitsubishi Heavy Industries inverter technology with excellent seasonal efficiency, achieving an A+++ energy efficiency rating in both cooling and heating modes. With a SEER of 9.50 and a SCOP of 5.20, the 25ZTX-WA provides high seasonal efficiency while keeping energy consumption under control.

The Kazan Arctic series is specifically designed for cold-climate operation. The SRK25ZTX-WA / SRC25ZTX-WA system is engineered to maintain efficient heating performance at very low outdoor temperatures. Its heating capacity ranges from 0.9 to 7.8 kW, with a maximum heating capacity of 4.8 kW at -15°C and 4.3 kW at -20°C.

The system uses the modern R32 refrigerant and features 3D AUTO airflow control, which automatically adjusts the direction of the air stream to provide more even air distribution throughout the room. The indoor unit operates from just 19 dB(A) at its lowest fan speed, making it particularly suitable for bedrooms and other noise-sensitive spaces.

The integrated Wi-Fi module allows convenient remote control from a smartphone, including temperature adjustment and selection of the operating mode.
