Best in class HVAC efficiency

Offers significant improvements in energy consumption thanks to the high Cooling EER up to 5.40. As VRF systems operate most of the time under part load conditions, (at 50% or less of full capacity), air365 Max features SmoothDrive 2.0. This unique technology controls the output of by precisely controlling the compressor speed and measuring the gap in room vs set temperature with an accuracy of 0.1C. This reduces wear and tear on the compressor by reducing compressor start/stop events, improves temperature stability, and reduces energy consumption at part load by up to 39%. [1]

VRF that is easy to work with

A complete solution that saves time and money at every stage of your project, from Design to Maintenance. Our complete ecosystem of indoor & outdoor units, smart apps and hardware features work together as a complete solution.
Highlights include…



  • Design VRF systems using fewer outdoor units with single unit capacity up to 30HP (maximum combination up to 120HP) and 200% indoor unit connection capacity.

  • Engineers can configure VRF outdoor units up to 4X faster using the airCloud Tap application [2] . Simply tap a smart phone near an outdoor unit or wired controller to access more than 200 setting parameters via NFC. For complex installations settings may be copy-pasted to multiple units in just a few clicks.

Tech behind the VRF unit

We remain true to our legacy of fine Japanese design and engineering. Every Hitachi Cooling & Heating system is designed to perform reliably & efficiently with innovative technology that sets the benchmark for the industry.



  • Unique Heat Exchanger Design: proprietary sigma-shaped (Σ) heat exchanger that features a new 3-way path structure which expands the heat-transfer area and efficiency, and contains around 6000 aluminum fins and 350 copper tubes.

  • In-house scroll compressor: Driven by a DC inverter motor and can operate in tiny increments of 0.1Hz, leading to a wider outdoor unit operating temperature range & better efficiency.
