The Fujitsu SET-ARTH45KHTA-3PH is a high static reverse cycle ducted air conditioning system designed for larger 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 complex ducted installations where higher static pressure is needed to maintain even airflow across multiple rooms. With 12.5kW cooling and 15.0kW heating capacity, this model is ideal for large living areas, multi-room homes, offices, and spaces around 55–90m² depending on insulation and layout. The system can modulate from approximately 4.0kW to 14.0kW in cooling mode and from 5.2kW to 17.0kW 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.

Strong Airflow Output

The system delivers approximately 903 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.

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 is often preferred for larger ducted systems.

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.

Energy Efficient Performance

The system delivers an EER of approximately 3.29 and a COP of 4.09, helping reduce ongoing running costs while maintaining strong heating and cooling performance. Fujitsu states that the newer R32 high static range is up to 19.7% more energy efficient than previous models.

Quiet Operation

Indoor sound levels are approximately 43dBA on high fan speed and as low as 35dBA 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 offers improved efficiency and lower environmental impact compared to older refrigerants such as R410A. Fujitsu notes that R32 has a significantly lower global warming potential than previous refrigerant types.

Wide Operating Range

The unit can operate in outdoor temperatures up to 50°C in cooling mode, making it suitable for harsh Australian summer conditions and year-round performance.

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 multiple areas throughout the property.

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.

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 and auto changeover.

UTY-RNRT Touch Controller Included

This system includes the Fujitsu UTY-RNRT backlit touch panel wall 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
• Commercial spaces
• Homes with long duct runs
• Zoned ducted systems
