The Fujitsu ARTH72KHTA is a 20.0kW high static ducted reverse cycle air conditioner designed for very large Australian homes with three-phase power supply. Paired with the AOTH72KRTA outdoor unit on a 400V three-phase supply, it provides whole-home cooling and heating through ceiling-mounted ducts with zone control support.
Inverter-driven and using R32 refrigerant, the ARTH72KHTA delivers 20.0kW of cooling and 22.4kW of heating. The 75m maximum pipe run offers significant installation flexibility for large properties. Three-phase power supply availability must be confirmed during site assessment before specifying this unit.
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 20.0kW High Static Ducted Reverse Cycle Air Conditioner (Three Phase)
▾The ARTH72KHTA is part of Fujitsu’s Large Capacity High Static ducted range, delivering 20.0kW of rated cooling and 22.4kW of rated heating in a three-phase reverse cycle system. The indoor unit installs in the ceiling cavity and the AOTH72KRTA three-phase outdoor unit is mounted externally.
The three-phase supply at 400V reduces running current to 9.9 A compared to an equivalent single-phase system, which can simplify electrical installation for large properties that already have three-phase power. Zone control directs airflow to specific rooms or areas.
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.
75m maximum pipe run for greater installation flexibility on large properties.
Three-phase 400V operation reduces running current compared to single-phase equivalents.
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 20.0kW High Static Ducted Reverse Cycle Air Conditioner (Three Phase) right for your home?
▾The ARTH72KHTA is estimated to suit homes with a total floor area of approximately 260 to 380 m2, making it suitable for very large Australian homes with five or more bedrooms, or properties with large open-plan areas and high glazing exposure. Actual coverage depends on insulation, ceiling height, glazing, sun exposure, number of zones and duct layout.
This unit requires a three-phase 400V power supply. Homes without existing three-phase power would require a supply upgrade, which adds cost and must be assessed by a licensed electrician.

Energy Efficiency & Performance
▾The ARTH72KHTA achieves an EER of 3.25 kW/kW in cooling and a COP of 3.85 kW/kW in heating under rated conditions. It carries a 2.5-star cooling and 2.5-star heating energy rating under average Australian climate zone conditions.
The inverter compressor adjusts output to match actual load. Three-phase operation provides a running current of only 9.9 A, making circuit design more straightforward than a single-phase equivalent at this capacity. Maximum input power is 7.26 kW.
