Water source VRF since 1954

Hitachi launched it’s first water-sourced AC product in 1954 (the FF500-FF750) with 1.6ton (7.5HP) capacity at the time. Our latest models are up to 18ton (85HP) per module, with the possibility to combine 3 modules to a single system

– Choose from Heat Pump or Heat Recovery Systems

Unified design and dimensions make it easier to deploy a mixture of Heat Recovery and Heat Pump units on a shared water loop, enabling the best balance of install cost and temperature control requirements for different zones.

Heat Pump type operates in either Heating or Cooling mode, making it suited for buildings where spaces share similar ambient temperatures, including both new buildings or refurbs looking for reliable winter heating solutions that can be based on renewables.

Heat Recovery type exchange heat energy in both the refrigerant circuit and the water loop, making them even more efficient than air-source heat recovery systems. They allow simultaneous cooling and heating in different zones; ideal where spaces have different levels of sun exposure and unequal occupancy – e.g. meeting rooms, public areas, classrooms, halls, etc.

– Exceptional energy efficiency and scalability

For projects where exceptional energy efficiency is a key objective, achieve up to cooling IEER 29.0 (Btu/Wh) and heating COP 6.31 (1). Individual module sizes range from 6-18 Tons and 48 Ton installations can be achieved by combining up to 3x 16 Ton modules.

– Flexible, slim, indoor installation

Experience the seamless integration of Hitachi's water source units inside your building, ensuring minimal impact on its appearance. With a compact chassis, these units easily fit into machine rooms or enclosed balconies and can be installed using stacked frames to save floor space. The flexible indoor-outdoor unit connection ratio of 50 – 130% allows for efficient system design, offering a wide selection of slim indoor unit types, including ducted, wall-mounted, cassette, floor-mounted, and concealed units. Connect up to 33 units on a single refrigerant loop for optimal flexibility and space utilization.

– Support your comfort & well-being

The water source VRF outdoor unit is designed to minimize operating noise, reducing it by up to 6dB for noise-sensitive areas, resulting in a low noise output of just 49dB. Additionally, with its indoor installation, heating operation is not interrupted by defrosting, ensuring continuous heating and optimal comfort.

In addition, we offer practical indoor air quality upgrades, such as the optional ViroSense Z filter for 4-way Cassettes, which provides 99.9% inhibition against SARS-COV-2(2), enhancing the air quality in your space.

– Protecting electrical components from condensate

Uses a mini refrigerant circuit to cool the electrical PCB, preventing the build-up of condensate and therefore improving reliability.
