Free up your walls, rethink your space. The slimline heat pump that’s recessed into the ceiling MLZ One-Way Cassette Series
MLZ SlimFit One-Way Cassette Series Recessed neatly into the ceiling, the slimline MLZ One-Way Cassette delivers all the performance of a traditional wall-mounted heat pump, without taking up wall space or compromising your décor. Its discreet, low-profile design provides quiet, comfortable airflow from above, blending seamlessly into modern interiors. With whisper-quiet, one-way airflow and an unobtrusive finish, it’s the ideal solution for design-conscious homeowners or where wall space is limited. *1 MLZ-KP25/35/50VG indoor unit height. *2 MLZ-KP25/35/50VG indoor sound level on lowest fan setting in Heating Mode. Slim Design Fits Where Others Can’t At only 185mm high, the MLZ SlimFit is New Zealand’s slimmest residential one-way ceiling cassette heat pump*1. It fits easily between New Zealand’s standard 450–600mm floor joists, making it ideal for townhouses, apartments, or two-storey homes where ceiling space is tight. Enjoy the benefits of a built-in system without lowering the ceiling or sacrificing room design. Blends Seamlessly with Your Home With a simple white grille that sits flush to the ceiling, the MLZ SlimFit disappears into your décor. It’s the ideal solution for design-focused homes with open-plan layouts, glazing, or minimal wall space, giving you total comfort without visual clutter. One-Way Airflow Design Ideal for rooms where one-way air distribution is required, and a solution for spaces where lighting fixtures are installed in the centre of a room, one-way airflow provides a comfort with no draughts. Whisper-Quiet Comfort Starting from just 26dBA, the MLZ SlimFit is New Zealand’s quietest one-way single-split cassette*2. Because it’s recessed into the ceiling, most of the sound stays there too – perfect for bedrooms, studies and living areas where quiet really matters. 26dBA*2
Set Airflow According to Ceiling Height Dual-level airflow selection lets you fine-tune the unit to suit your room’s ceiling height. This is key for adjusting airflow effectively when it is either too strong or too weak due to being mismatched with the height of the ceiling. Airflow Tailored to Preference Outlet vanes can be moved left and right, and up and down using the remote controller. This allows you to direct airflow exactly where you want it for tailored, even comfort throughout the room. Capacity Class 25 35 50 Standard 2.4m 2.4m 2.4m High Ceiling 2.7m 2.7m 2.7m Horizontal Airflow Horizontal Airflow gently spreads air across the ceiling before it circulates through the room, avoiding the feeling of direct draughts – ideal for bedrooms, offices or living rooms. Next-Generation R32 Technology The MLZ SlimFit One-Way Cassette features the latest in superefficient and more environmentally friendly R32 refrigerant. With a global warming potential that is 30% lower compared to older refrigerants such as R410A, next generation R32 refrigerant has a much lower environmental impact. Furthermore, zero ozone depleting R32 is easier to reuse and recycle. Optional Wi-Fi Control Upgrade By adding optional Wi-Fi Control you can pre-heat or cool a room no matter where you are.
