– Geographic Universality
Equipped with high efficiency fixed speed Hitachi compressors, PRIMAIRY offers powerful cooling and heating performance within a wide ambient temperature range, so its settings can be configured to handle any local profile.
- Cooling mode: -15 ~ 43℃
- Heating mode: -10 ~ 24℃

– Excellent cooling and heating performance delivers exceptional comfort
Powerful cooling performance at standard and low 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
Optimized fan speed in outdoor unit is based on actual load, that means higher efficiency and increased energy saving.
The smart defrost software and added defrost sensor precisely control the defrost time and effect, which can effectively eliminate defrost delay.

– Reliable partners for small businesses
How to know when a product is truly safe?
Multiple features and safety functions have been added to Hitachi air-conditioning units over the years as a function of continuous research and adaptation to make us 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.
- Refrigerant leakage detection: The indoor unit will stop operation automatically and show an error code when the refrigerant charging level is lower than 30%, to prevent compressor damage.
- The smart defrost software and added defrost sensor precisely control the defrost time and effect, which effectively prevents defrost delay.

– Think ahead and Easy Maintenance
PRIMAIRY’s expansion interface enables connection to a smoke detector, key slot or other device.
When the unit stops running, the error code is clearly displayed on the diagnostic panel of the outdoor unit for quick troubleshooting and maintenance. Units can automatically return to previous operating settings after a power outage, for simplified operation.

– Flexible and Convenient
Compactness and lightness: Free of unnecessary or weighty components, each unit can be easily organized into place by the installation team.
Up to 50m piping run and 30m height applications can be installed, for high flexibility in customizing system configuration
