The Fujitsu SET-ARTH54KHTA-HP is a high performance reverse cycle ducted air conditioning system designed for large homes and demanding installations that require long duct runs, stronger airflow, and higher static pressure. Compared to the standard ARTH54KHTA, the High Performance version is designed to deliver stronger airflow and improved performance across larger or more complex ducted layouts. 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 Performance Static Pressure

The High Performance range is engineered for installations requiring stronger airflow and higher duct resistance, making it ideal for long duct runs, multiple outlets, and larger zoned systems. Fujitsu’s high static range supports static pressure from 60Pa up to 260Pa, helping maintain more consistent airflow throughout the home.

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 rooms.

Single-Phase Power Supply

This model operates on standard 230V single-phase power, making it suitable for most residential properties without requiring 3-phase electrical upgrades. Running current is approximately 20.4 amps in cooling mode and 19.3 amps in heating mode.

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.

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.

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.

R32 Refrigerant

The system uses modern R32 refrigerant, which provides 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.

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.

Zone Control Compatible

The High Static Single 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.

Demand Response Ready

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

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.

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.

Ideal Applications

• Large homes
• Open-plan living areas
• Multi-room homes
• Offices
• Homes with long duct runs
• Zoned ducted systems
• Installations requiring stronger airflow

Why Choose the Fujitsu SET-ARTH54KHTA-HP?

The Fujitsu SET-ARTH54KHTA-HP is a powerful and flexible ducted solution designed for homes and commercial spaces that require stronger airflow and higher static pressure performance than a standard ducted system. With its high performance airflow design, strong static pressure capability, R32 refrigerant, included UTY-RNRT controller, and compatibility with zoning and Wi-Fi control, it is an excellent option for larger homes and more demanding ducted installations.
