The Fujitsu SET-ARTH54KHTA-3PH is a high static reverse cycle ducted air conditioning system designed for large homes and commercial spaces that require long duct runs, strong airflow, and reliable zoning performance. It is ideal for large open-plan homes, offices, and more complex ducted installations where higher static pressure is needed to maintain even airflow across multiple rooms. With 14.0kW cooling and 15.5kW heating capacity, this model is ideal for large living areas, multi-room homes, offices, and spaces around 65–95m² depending on insulation and layout. The system can modulate from approximately 5.0kW to 16.0kW in cooling mode and from 5.1kW to 18.0kW in heating mode, helping maintain stable temperatures while reducing energy use.

Key Features & Benefits

High Static Pressure Performance

The unit offers a static pressure range from 60Pa to 260Pa, making it suitable for long duct runs, multiple outlets, and demanding ducted layouts where standard slimline systems may struggle. Fujitsu’s automatic static pressure adjustment helps installers optimise airflow without extensive manual balancing. (fujitsugeneral.com.au)

Strong Airflow Output

The system delivers approximately 986 litres per second of airflow on high fan speed in both cooling and heating modes, helping provide even air distribution across larger homes and multiple zones. (fujitsugeneral.com.au)

3-Phase Power Supply

This model operates on 400V 3-phase power, making it suitable for homes and commercial properties with 3-phase electrical supply. Three-phase power can help spread electrical demand more evenly across circuits and reduce current draw compared to equivalent single-phase systems. (fujitsugeneral.com.au)

Compact Indoor Unit Design

The indoor unit measures approximately 425mm high, 1250mm wide, and 490mm deep, while the outdoor unit measures approximately 998mm high, 940mm wide, and 320mm deep. Despite its high static capability, the system remains compact enough for a wide range of roof space installations. (polyaire.com.au)

Energy Efficient Performance

The system delivers residential cooling seasonal performance factors up to 4.39 and heating seasonal performance factors up to 4.69 in hot climates, helping reduce ongoing running costs while maintaining strong heating and cooling performance. Fujitsu’s R32 high static range is designed to improve efficiency while delivering balanced power distribution. (fujitsugeneral.com.au)

Quiet Operation

Indoor sound levels are approximately 45dBA on high fan speed and as low as 36dBA on quiet mode. Outdoor sound pressure levels are approximately 55dBA in cooling mode and 57dBA in heating mode, helping maintain quieter day-to-day performance. (fujitsugeneral.com.au)

R32 Refrigerant

The system uses modern R32 refrigerant, which offers improved efficiency and a significantly lower global warming potential than older refrigerants such as R410A. Fujitsu notes that R32 has around 67% lower GWP than R410A. (fujitsugeneral.com.au)

Wide Operating Range

The unit can operate in outdoor temperatures from -10°C to 50°C in cooling mode and from -15°C to 24°C in heating mode, making it suitable for Australian climate conditions year-round. (fujitsugeneral.com.au)

Zone Control Compatible

The High Static Three Phase R32 range is compatible with Fujitsu zone control systems, allowing users to independently manage airflow to different parts of the home for improved comfort and energy savings. Optional zone control can support up to eight zones. (fujitsugeneral.com.au)

Demand Response Ready

The system supports demand response programs, allowing the unit to reduce energy usage when required by electricity providers. It also includes features such as auto restart, economy mode, and auto changeover. (fujitsugeneral.com.au)

Blue Fin Heat Exchanger

The outdoor unit features Fujitsu’s Blue Fin heat exchanger coating, which improves corrosion resistance in coastal areas and helps extend the lifespan of the outdoor unit. (polyaire.com.au)

UTY-RNRT Touch Controller Included

This system includes the Fujitsu UTY-RNRT LCD touch panel controller for simple temperature adjustment, operating modes, scheduling, and zone control integration. Optional Wi-Fi control is also available through Fujitsu anywAiR® technology. (mckinnonheating.com.au)
