The Fujitsu SET-ARTH45KHTA 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 more 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 5.6kW to 14.5kW 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.
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.
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. Rated input power is approximately 3.8kW in cooling mode and 3.42kW in heating mode.
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 substantially lower global warming potential than previous refrigerants.
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.
Demand Response Ready
The system supports demand response programs, allowing the unit to reduce energy usage when required by electricity providers.
UTY-RNRT Touch Controller Included
This system includes the Fujitsu UTY-RNRT touch panel controller for simple temperature adjustment, operating modes, scheduling, and zone control integration. Optional Wi-Fi control through Fujitsu anywAiR® technology is also available.
Ideal Applications
- Large homes
- Open-plan living areas
- Multi-room homes
- Offices
- Commercial spaces
- Homes with long duct runs
- Zoned ducted systems
