Modular TopFlow High Efficiency Heat Recovery

air365 Max Pro is a heat pump VRF with optimal energy efficiency and effortless comfort. It's an end-to-end solution that's easy to work with, ideal for HVAC pros and building owners seeking cost-efficient and adaptable HVAC systems.

– Best in class HVAC efficiency

Offers significant improvements in energy consumption thanks to the high Cooling IEER up to 6.20 and Heating COP up to 5.13 (Singapore NEA certification). 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 22HP and indoor unit connection capacity
- Engineers can configure VRF outdoor units up to 4X faster using the airCloud Tap application(2). 200%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.

– Seamless comfort

Seamless comfort for building occupants, anywhere, anytime. Solves common problems of HVAC solutions including unstable temperatures, cold or hot drafts, direct air, hot and cold rooms during season changes, and more.
- Constant indoor temperature even during part-load operation with SmoothDrive 2.0
- Original & leading-edge technology including GentleCool and CrowdSense, for enhanced occupant comfort
- Neighborhood-friendly outdoor unit with 4dB(A) lower noise output on average (Night Shift mode)
- Purifying your indoor air with our affordable IAQ solutions including ViroSense filters and the AQtiv-Ion ionizer kit

– 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
- Gas injection 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.

– HVAC solutions for specialist needs

A series of optional accessories for outdoor units ensure reliable operation even in extreme weather or marine environments.
1. Protection net: for locations where there occupants or passers-by may be near the outdoor units
2. Air outlet duct kit: air from the fan-outlet can be directed at a certain angle to avoid obstacles or other equipment
3. Snow protection hood: protects against heavy snowfalls ensuring you can run in cooling mode even if outdoor temperatures fall to -10 degree. In heating mode it can operate even without a snow protection hood down to ambient temperatures of -25 degree

– Other Benefits

IEER - Integrated Energy Efficiency Ratio

VRF Systems' patented Sigma-shaped heat exchanger and gas injection scroll compressor provide best-in-class energy efficiency, achieving up to IEER 6.20 (NEA certified) and offering cost-effective HVAC solutions for residential and commercial use.

Energy consumption at part-load

Thanks to our original direct capacity control technology SmoothDrive, energy consumption can be reduced by up to 39% during part-load operation (when the system is running at 50% or less of its capacity) (1)

Indoor unit connection ratio

Lower purchase costs with up to 200% indoor unit to outdoor unit connection ratio. It's e a cost-effective solution for commercial settings looking to install HVAC systems that provide efficient temperature control while being budget-friendly.

Faster configuration and quick installation

Engineers can configure VRF units 4X faster using the airCloud Tap app. Simply tap a smartphone near an outdoor unit to access more than 200 setting parameters via NFC. For complex installations settings may be copy-pasted to multiple units (2).

Oil return operation for balanced temperature

Our patented oil return control cycle runs for only 60 seconds (cooling mode) every hour for reliable performance and a balanced indoor environment. This technology helps prevent compressor damage and boosts energy efficiency in HVAC systems.
