Outdoor unit lineup

Standard combination and compact size

Space efficiency has been achieved by significantly reducing the chassis of the outdoor units compared to previous models.

Reduces the number of systems and installation area

Since the installation area can be reduced, the reduced space can be used for other purposes. For example, the area can be used as a biotope to contribute to a sustainable future by greening it.

Comparison of multiple 80 HP systems installed, for example

Contributes to reduction of project costs

Up to 80HP can be selected for a single refrigerant system. This reduces the number of outdoor units and materials required for installation (piping, power lines, communication lines, racking, breakers, conduit, etc.) compared to conventional products. This product is designed to reduce project costs.

Energy saving technology that boosts operation efficiency

Powerful large propeller fan

By using CFD^*1 technology, a newly designed fan achieves high performance and low noise operation.

3 phase DC fan motor

Efficiency is substantially improved by high efficiency motor with sophisticated driver control. In addition, low noise is realized by DC fan motor.

Subcool heat exchanger

High Heat Exchange efficiency is achieved by using an internal projection shape double pipe construction.

Sine wave DC inverter control

High efficiency is realized by adoption of reduced switching loss IPM.

High system flexibility

The industry-leading high static pressure, long pipe design, and connection capacity, enable flexible installation on each floor and installation of various indoor units.

4-face heat exchanger

Heat exchange efficiency is significantly improved by the introduction of a 4-face heat exchanger that increases effective surface area.

14-20HP only

High Performance Scroll Compressor

The combination of a scroll compressor and our proprietary sensorless sine wave control that smoothly controls the input power into the motor can achieve a wider rotational frequency range from 15 to 120rps, resulting in high energy-efficiency and quieter operation.

Wide operating range

Designed to perform at ambient temperatures as high as 55°C. Installation in extreme temperature conditions is possible due to an increased operational range.

Intelligent refrigerant control

Fujitsu General is proposing outdoor units equipped with refrigerant control function. The refrigerant control operates with suitable control corresponding to the heat load of the room and offers a more comfortable environment. The refrigerant control also provides increased energy savings.

Class leading High energy efficiency

The use of our proprietary heat exchanger structure and high-efficiency Scroll compressors achieves class leading Energy Efficiency Ratio (EER) in every combination.

Energy Efficiency combinations

Overall piping length Max. 1,000 m

World’s top class overall piping length of 1,000 m allows for application in a wide variety of buildings.

700m in case of single outdoor unit

New refrigerant cooling technology

New Refrigerant Cooling Technology, ensures the stability of PCB temperature and improves reliability at high ambient temperatures. It is possible to cool the inverter power module even at high ambient temperatures. This helps to maintain air conditioner capacity and also ensures efficient and reliable operation.

Silicon coated PCB

High-ambienttemperature- compatible electronic components are used. Silicon coating is applied to all PCB circuits for corrosion protection.

High anti-corrosion screw

Zinc-chrome-acid film treatment applied to all screws.

Anti-corrosion coated casing parts

Satisfied the JRA* anti-corrosion regulation (9002)

Blue fin heat exchanger

Blue fin treatment of the condenser offers improved corrosion resistance and longer life of the heat exchanger. Adoption of blue coating for the fins in the heat exchanger provides protection against rust and salt damage.

PCB Protection Low - High voltage support

Even if the product is installed in an area where the power supply (voltage) is not stable, the PCB that controls the product is protected, so the product can be installed with peace of mind. For example, even if the system goes down due to factors such as lightning strikes, the system will operate at its original operational content when the power is restored, making management easy.

Protects against power supply mis-wiring

Even if there is a mistake in the wiring connection during the "reverse phase," "phase loss," or "missing phase" of the power connection during installation, the product will not be damaged and can be installed with peace of mind.

Easy maintenance

Service panel

The split service panel allows for maintenance from the top or bottom of the outdoor unit.

*

The bottom panel can not be removed without removing the top panel.

Easy-to-read 7-segment indicator lamp

Shows the following detailed operation and error status without the need of any special tools.

Error status can be checked on an outdoor unit's display

• System operation mode
• Discharge temperature and pressure
• Compressor operation status
• Address, type, and number of outdoor units

Automatic address setting

The address of the indoor unit and signal amplifier can be set through the automatic function setting on the outdoor unit PCB.

Various combinations

Avaliable in various combinations from 8HP to 80HP increments. Indoor units can be selected ranging from 2.2kW to 28kW capacity. Upto a maximum of 150% indoor unit connectable capacity.
