• 2-pipe R410A system from 4HP to 8HP
• Cooling duty between 10kW and 24kW
• Also available as a single split system

High Pressure Scroll
Hitachi use their own vertical scroll compressor in their VRF systems. This operates at a higher pressure than its competitors, enabling better oil management and discharge pressure.

Both top flow and side flow VRF systems offer cooling and heating modes via heat pumps, heat recovery technologies, and hot water creation.

Individual Remote Control
Each system can be controlled and with schedules set at long range, thanks to the airCloud Pro app.

Cost Effective Designs
Hitachi's centralized controller offers a lower cost control system, enabling any type of wiring route based on layout rather than AC system structure.

Improved Air Quality
ViroSense Z2 filter for 4-way Cassettes, and the Aqtiv-Ion kit for Ducted indoor units, offer a 99% effective on a range of viruses and bacteria, including SARS-CoV-2.
