Mitsubishi Heavy Industries | Bronte 6.3kW Split System 240V | Built-in Wi-Fi
The Mitsubishi Heavy Industries DXK21ZRA-WF1-SET is a 6.3kW reverse-cycle split system for large living spaces and open-plan areas. Built-in Wi-Fi allows remote control via the Smart M-Air app, with voice command integration for Amazon Alexa and Google Assistant. It delivers powerful cooling to 6.3kW and heating to 7.1kW, with dual-layer air filtration and long-reach airflow up to 18 metres.
Large modern homes often struggle with uneven temperature distribution and poor air quality during heating and cooling cycles. Open-plan layouts, extended wall lengths, and retrofit applications require an air conditioner that can move air quickly and effectively across the entire space. The DXK21ZRA-WF1-SET addresses this with 18-metre long-reach airflow that distributes conditioned air across large rooms without creating hot or cold spots. The unit's NOVAShield™ PM2.5 filter and Allergen Clear system capture fine particles and improve indoor air quality. This is a key consideration for families managing dust, pollen, and allergens year-round.
Tradies and property managers value the DXK21ZRA-WF1-SET for its retrofit simplicity and remote monitoring capability. The built-in Wi-Fi eliminates the need for aftermarket modules; installers can commission the unit and hand over app access to homeowners immediately. The Smart M-Air app allows technicians to monitor operating status, schedule timers, and track power consumption remotely, reducing call-backs for minor adjustments. The unit's 5-year manufacturer warranty covers parts and labour, and its R32 refrigerant pre-charge to 15 metres cuts installation complexity on standard residential runs.
