The Fujitsu ARTH45KHTA is a 12.5kW high static ducted reverse cycle air conditioner suited to medium-large Australian homes, with an estimated total floor area coverage of approximately 150 to 230 m2. Paired with the AOTH45KBTA outdoor unit on a standard single-phase 230V supply, it provides whole-home cooling and heating through ceiling-mounted ducts with zone control support.
Inverter-driven and using R32 refrigerant, the ARTH45KHTA operates in cooling mode up to 50°C ambient and in heating mode down to -15°C. The larger indoor cabinet supports higher airflow volumes and static pressure capability for more complex duct layouts.
Final sizing should be confirmed through an on-site assessment, as insulation, ceiling height, glazing, sun exposure and room layout can all affect the right unit choice.
Overview of Fujitsu 12.5kW High Static Ducted Reverse Cycle Air Conditioner
▾The ARTH45KHTA is part of Fujitsu’s High Static ducted range, delivering 12.5kW of rated cooling and 14.0kW of rated heating in a reverse cycle system for year-round whole-home comfort. The indoor unit installs in the ceiling cavity paired with the AOTH45KBTA outdoor unit.
Air is distributed through field-supplied branch ducts and zone control can direct airflow to specific rooms. The system supports static pressure up to 180 Pa for more demanding duct configurations.
Zone control for room-by-room airflow management.
Inverter compressor for variable-capacity operation and stable temperatures.
R32 refrigerant — approximately 67% lower global warming potential than R410A.
High static pressure up to 180 Pa for longer duct runs and more zones.
Economy mode for reduced energy draw during light-load periods.
Auto changeover between heating and cooling modes.
Ambient cooling operation up to 50°C.
Optional WiFi control via UTY-ANY2 anywAiR module (not included standard).
Is the Fujitsu 12.5kW High Static Ducted Reverse Cycle Air Conditioner right for your home?
▾The ARTH45KHTA is estimated to suit homes with a total floor area of approximately 150 to 230 m2, making it suitable for medium-large Australian homes with four to five bedrooms. Actual coverage depends on insulation, ceiling height, glazing, sun exposure, number of zones and duct layout.
Zone control allows conditioned air to be directed to occupied areas only, improving comfort and efficiency. The larger airflow capacity of this model supports more zone branching points in the duct design.
