R32 Low GWP Refrigerant

With sustainability as our top priority, the R32 refrigerant is rated with Zero Depletion Potential and a reduced Global Warming Potential, contributing to the protection of the environment and the future of our planet. Hitachi airCore600 employs R32 as its refrigerant to uphold our commitment to sustainability and environmental responsibility, resulting in a reduced GWP from 2090 to 675, comparable in performance to R410a refrigerants.

High efficiency

Hitachi airCore600 is equipped with a high-efficiency compressor that delivers powerful cooling performance at standard and high ambient temperatures. This high efficiency is attributed to the high-performance twin rotary compressor. The twin rotors balance out the centrifugal load resulting from rotation, reducing compressor vibration, lowering noise levels, and increasing reliability.

No matter how harsh the outdoor temperature is, airCore units are able to operate at temperatures ranging from as low as 16°C up to 48°C. This provides high performance across a wide ambient temperature range.


Economic Operation

An impressively low operating cost is a key advantage of inverter air conditioners. We've combined advanced inverter technologies with cutting-edge electronics and mechanical technologies to achieve a synergistic effect that enables improvements in heating/cooling performance efficiency. The results are better performance and lower energy consumption.


Easy Maintenance

Convenience is important, especially in our busy working lives. Several features have made AC maintenance easier. These include an interlock control interface with external devices, which allows you to connect to smoke detectors, key slots, or other devices; an error self-diagnosis function that helps scan your system to identify specific problems, making repairs more efficient; and auto-random restart, which prevents the units from overloading the circuit with power simultaneously.


Prevention and Protection

Hydrophilic aluminum coating prevents water and mineral deposits on the heat exchanger, maintaining long-term energy efficiency. Refrigerant leakage detection and alarm functions are available to ensure the safety of your AC system.

Wide choice and flexibility indoor units loved by designers and installers

Light Commercial systems have a wide choice of indoor units, including Cassette, Ducted units and floor/ceiling covertable units.



Inventor of the 4-way cassette

For decades, small commercial split systems used only floor-standing units, which tended to result in drafts and uneven air distribution. In 1984 Hitachi invented the 4-way cassette, enabling much improved air distribution in open-plan offices, shops, and other commercial spaces – even those with high ceilings.

2 different grid sizes

Today Hitachi’s range of 4-way cassettes for small commercial split systems can be found in meeting rooms, restaurants, open plan offices, retail stores and galleries all over the world. Our current range come in 2 different physical sizes, each designed to fit a standard ceiling grid, and they can be easily incorporated between light panels and other overhead fixtures.

Wide airflow distribution & easy maintenance

Louvres can be opened up to 90° ensure a wide angle of possible air flow paths. Meanwhile, the integrated filter can be removed and washed in minutes without needing to be a qualified HVAC technician.

Affordably integrate 1-way ventilation

A Fresh Air Inlet port enables outdoor air to be sucked into the unit and mixed with the conditioned airstream; an effective and low-cost way to introduce basic one-way ventilation to a commercial space, by simply connecting piping from the unit to the outdoors.

Temperature compensation for high ceilings

When installing in high ceilings above 2.5m, building managers can easily implement a temperature compensation mode using the optional wired room controller. This avoids the problem of inaccurate room temperature sensing when the cassette unit is high above floor level.



Integrates with the interior design of any space

Ducted units for small commercial split systems are available in a range of capacities and sizes, and are ideal for architects, interior designers, HVAC specialists and businesses looking for a way to integrate air conditioning discreetly into ceiling plenums. In fact, any space with a focus on design aesthetics – premium offices, hotels, lounges, restaurants & bars – will want to consider a ducted solution because the equipment is effectively hidden in the ceiling.

One unit, multiple air vents

A single ducted unit can be installed and connected to multiple air outlets, improving air distribution and potentially reducing capital investment as neighboring spaces could share a single unit with adequate capacity. Adjustable ESP (External Static Pressure) from 0-120Pa depending on model, supports multiple air outlets from a single unit, and ensures there is enough air pressure to navigate corners and turns in the ductwork.

From just 190mm height

Compact design minimizes the space between the cement and dropped ceiling, otherwise known as the ‘ceiling plenum’ or a ‘false ceiling’, allowing more usable height space within the room. The air return port can be connected from underneath or behind the unit, further increasing flexibility for space layout and installation.

Drainage Protection System prevents condensation damage

The design of the integrated drain pan allows condensation water to flow smoothly without leakage and prevent rust. If the drainpipe becomes clogged the unit will be automatically disabled to prevent water leakage.

Silent operation

Our ultra-quiet ducted units have a noise range starting from just 26dB-33dB on our smallest units (from low to high fan speeds), meaning that even in very quiet spaces the air conditioning would be hardly audible.

Floor/Ceiling Convertible


One unit, multiple uses

Because it can be fixed on the floor or suspended from a ceiling, it simplifies purchasing and installation by using a common unit type for different rooms and installation scenarios. Ideal for businesses looking to minimize installation costs, and don’t mind having a suspended unit visible in the ceiling or mounted to the floor, or for buildings where there is no suitable ceiling cavity to install ducted or cassette units.

Ceiling installation

Ideal for med-sized open-plan offices, classrooms, restaurants, or any other open space with a lot of furniture at ground level – by distributing air from the ceiling these units can provide effective and even coverage across a room.

Floor installation

Perfect for small offices, shops and studios that lack empty wall space above waist height, in floor mode the unit projects conditioned air out of the top, while taking returned air in the side. It is also popular for loft and attic spaces converted to commercial use, where there is no available ceiling space and even wall space is limited.

Protection from condensation

The integrated drain pan uses high-strength steel and a composite foam to improve the thermal insulation and anti-condensation properties of the unit.

Affordably integrate 1-way ventilation

Fresh Air Inlet port enables a pipe to the outside of the building to be connected, sucking in outdoor air and mixing with the conditioned airstream; an effective and low-cost way to introduce basic one-way ventilation to a commercial space.

Low vibration & noise

Moulded plastic fan housing ensures rigidity and therefore reduces vibration and noise caused by the fan.
