Outdoor Units

Indoor Units

– Eco-friendly Refrigerant

With sustainability as a priority, the R32 refrigerant is rated to have zero depletion potential and lower global warming potential which helps protect the environment and our planet's future.

– Excellent cooling performance delivers exceptional comfort

Equipped with high efficiency fixed speed compressors, PRIMAIRY offers powerful cooling performance within a wide ambient temperature range all the way down from 16°C to up to 46°C. Its settings can be configured to handle your local profile.

– Excellent cooling performance delivers exceptional comfort

Powerful cooling performance at standard and high ambient temperatures. High performance twin rotary compressor delivers high efficiency. Twin rotors balance out centrifugal load caused by rotation. Reduced compressor vibration, lower noise level, and increased reliability.

– Advanced technology brings high efficiency and low energy consumption

The fins are an integral component of the unit that transfers and radiates heat. With our newly refined design, the fins facilitate improved heat exchange and contribute to greater efficiency, making it a energy-effective choice.

– Reliable partners for small businesses

An encompassing metal box design ensures full product safety. High pressure and low-pressure switches maintain the reliability of the system and the compressor. Temperature protection system, galvanized steel finish, durable production drainage system, and discharge temperature sensor ensure the AC systems’ smooth and secure operation.

– Prevention and Protection

A hydrophilic aluminum fin enhances heat exchanging performance by increasing water movement on fin surfaces and preventing water droplets from creating blockages between fins.
When the sensors detect a refrigerant leakage, the indoor unit will automatically shut down, protecting the compressor from damage caused by high temperatures. It will also display an error code, which will identify the refrigerant leakage and help with diagnosing the appropriate solution.

– Flexible and Convenient

With sustainability as a priority, the R32 refrigerant is rated to have zero depletion potential and lower global warming potential which helps protect the environment and our planet's future.

– 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.

Cassette

– Inventor of the 4-way cassette

For decades, light 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 light 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.

Ducted

– Integrates with the interior design of any space

Ducted units for light 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.

– Wide ESP range

A wide ESP range means PRIMAIRY is suitable for spaces with many discrete areas, including corners and recesses.
Multiple outlets can be connected to the ducted unit to ensure uniform air delivery even around tight spaces.
This system is easy to assemble quickly and accurately.

– Durable Protection Drainage System

This specially designed drain pan prevents leaks while effectively allowing condensate water to drain better, preventing rust for longer unit life. When the drain pipe is clogged and the water rises to a certain level, the float switch will send a signal to turn off the unit.

– Silent operation

Our ultra-quiet ducted units have a noise range of just 40-46dB 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.
