City Multi Hybrid VRF from Mitsubishi Electric combines refrigerant and water-based technology for efficient, reliable climate control. Refrigerant is used between the outdoor and branch controller, while water is used as a heat exchange medium between the branch box and indoor units. It offers flexible design, phased scalability, and AS/NZS 5149 compliance for medium—to large-scale applications.

City Multi Hybrid VRF
PURY-M(MP)-YNW-A1(-BS)
City Multi Hybrid VRF
The Hybrid VRF is part of the CITY MULTI product range, which consists of VRF air conditioning units that use refrigerant between the outdoor unit and the branch controller, and water between the branch box and the indoor units, designed for medium to large scale applications. Efficiency and reliability are at the very core of the Mitsubishi Electric Hybrid VRF systems.

CMB-WM108-1016V-AA/AB
The Hybrid VRF is part of the CITY MULTI product range, which consists of VRF air conditioning units that use refrigerant between the outdoor unit and the Hydro Branch Controller (HBC), and water between the Branch Controller and the indoor units, designed for medium to large scale applications.
City Multi Hybrid VRF
CMB-WM350/500F-AA
The new floor standing Vertical HYBRID Branch Controller (HBC) is designed with flexibility in mind. Key components of the Vertical HBCs are accessible from the front and at floor level during commissioning, meaning there is no need to break into the ceiling. The Vertical HBC is available as a 6-port main unit, with new compact 8 or 16-port sub-HBC options.

City Multi Hybrid VRF from Mitsubishi Electric combines refrigerant and water-based technology for efficient, reliable climate control. Refrigerant is used between outdoor and branch controller, while water connects branch box to indoor units, offering flexible design, phased scalability, and AS/NZS 5149 compliance for medium to large-scale applications.
The City Multi Hybrid VRF operates through a dual-circuit system controlled by the Hydro BC Controller (HBC):
Refrigerant-based heat transfer occurs between the outdoor unit and the HBC, where the HBC contains dedicated heat exchangers for the refrigerant-to-water energy transfer process. Outdoor units are available in two configurations:
Water circulates from the HBC to individual indoor fan coil units, with the HBC managing water flow and temperature control. This secondary circuit eliminates refrigerant from occupied spaces while maintaining individual zone control.
Temperature management can be executed through:
The HBC serves as the system’s central component, housing:
Refrigerant in Occupied Spaces: Enhanced Safety and Compliance
City Multi Hybrid’s innovative design uses water between the Hydro BC Controller (HBC) and indoor units, eliminating refrigerant from occupied spaces. This breakthrough delivers multiple advantages:
By using water as the heat transfer medium in occupied spaces, City Multi Hybrid offers the perfect balance of performance and safety without compromising energy efficiency.
The water circulation system between the HBC and indoor units provides naturally stable temperatures throughout the year. The Hybrid City Multi creates a more comfortable environment by delivering milder off-coil temperatures. This water-based approach helps maintain consistent temperature levels across different zones.
The 2-pipe heat recovery system reduces energy consumption during simultaneous cooling and heating operations. The energy-saving benefits increase with more frequent simultaneous operation. Additional efficiency gains can be achieved through centralised control and scheduled operation features, helping to optimise system performance.
