⚠️ Indoor unit only — this unit cannot cool or heat on its own. It only works together with a matching outdoor unit (sold separately, not included).
Mitsubishi Heavy Industries inverter air conditioner delivering 21000 BTU (6 kW) cooling. Quiet operation, energy-efficient, designed for year-round comfort.
Features & Highlights
Top Energy Class with Environmental Care
The Mitsubishi Heavy Industries SRK60ZSX-WF / SRC60ZSX-W inverter air conditioner stands out with exceptionally high energy efficiency — class A+++ in both heating and cooling — thanks to DC-PAM inverter technology, a twin-rotary compressor and the environmentally optimised R-32 refrigerant.

Allergen-Deactivating System
A two-filter system with a self-cleaning function ensures a healthy indoor environment. The allergen-deactivating filter completely destroys pollen, parasites and allergens that exist in pet hair. It also neutralises and eliminates all types of bacteria, moulds and viruses — and even if they detach from the filter, they have already been deactivated.
The photocatalytic deodorising filter protects against unpleasant odours, and the self-cleaning function prevents moisture from being trapped inside the air conditioner. As a result, the air in the room is always clean and fresh.

Full Airflow Control with 3D AUTO
With one button press you activate the programmed 3D AUTO airflow distribution. It performs three independent airflow controls, so the air is evenly distributed, quiet and reaches every corner of the room. Economical operation is achieved and energy losses are minimised. Thanks to automatic flow-rate and direction control, the entire room is comfortably air-conditioned in the most efficient way.

Presence Sensor
The Mitsubishi Heavy Industries SRK60ZSX-WF / SRC60ZSX-W inverter air conditioner has a built-in sensor that detects human activity in the room and automatically adjusts cooling/heating power for greater comfort and lower energy consumption. If the sensor detects no presence for 15 minutes, the unit automatically reduces output to a moderate level and returns to normal operation when someone is in the room again. If the room remains empty for 60 minutes, the unit switches to standby mode and resumes work once presence is detected. After more than 12 hours of absence, the air conditioner switches off completely.

Jet Technology
Mitsubishi Heavy Industries applied the aerodynamic analysis used in designing jet engines to develop the innovative Jet technology. The air stream produced by the JET Air Scroll system delivers a large volume of air with minimal energy consumption — the airflow is even, gentle, very quiet (down to 19 dB) and reaches the most distant corners of the room.

Twin Flaps and Removable Front Panel
The removable front panel provides direct access to the allergen-deactivating filter for instant air purification. The twin flaps optimise the airflow in cooling and heating mode to maximise comfort in the room.

Wide Operating Range Down to -20 °C
Thanks to a wide operating range, the Mitsubishi Heavy Industries SRK60ZSX-WF / SRC60ZSX-W inverter air conditioner works reliably in heating mode even at outdoor temperatures down to -20 °C. Warmth doesn't leave your home even on the coldest winter days.

Legal Notices — Installation & F-Gas Regulation
Fluorinated greenhouse gases: This unit contains the refrigerant R-32 (GWP 675 as stated by the manufacturer — refrigerant type, charge and CO₂ equivalent in the product data sheet). Installation, maintenance and disposal must be carried out by a certified technician in accordance with EU Regulation 517/2014 (revised by Regulation (EU) 2024/573). For customers in the United Kingdom, the UK F-Gas Regulations 2015 (as retained EU law) apply equivalently.
Installation: Self-installation is not permitted. On request we can arrange a certified F-Gas installer in your region.
Frequently Asked Questions
How do I choose the right BTU size for my room?
The key figure is the manufacturer’s recommended room size for this unit — you will find it in the product’s technical data. For sun-facing or top-floor rooms, we recommend the next larger capacity class. Our team is happy to advise.
Do I need a certified technician for installation?
Yes — split air conditioners with fluorinated refrigerant must be installed by a certified F-Gas technician (EU Regulation 517/2014). Self-installation is not permitted. We can arrange a qualified installer in your region.
What warranty is included?
Standard manufacturer warranty is 36 months on the unit, provided installation is carried out by a certified F-Gas technician. Detailed warranty conditions are in the product datasheet.
What do SEER and SCOP mean?
SEER (Seasonal Energy Efficiency Ratio) is the seasonal cooling efficiency — higher is better. SCOP (Seasonal Coefficient of Performance) is the seasonal heating efficiency. SEER ≥ 6.0 and SCOP ≥ 4.0 are considered very good for residential split air conditioners.
