High efficiency
Heat recovery technology
MV6R heat recovery outdoor units can perform both cooling and heating operation simultaneously and independently within the same system, ensuring the maximum operating flexibility for the users. Heat recovery is achieved by diverting exhaust heat from indoor units in cooling mode to areas requiring heating, minimizing the heat exchange with outside environment. As a result, power input and electricity costs are minimized, ensuring the best energy efficiency. In addition, inverter technology allows to adapt precisely to variable capacity loads.
Independent control of heat exchangers and compressors
Both in cooling and heating mode, the outdoor heat exchanger and compressor are independently controlled to improve performances.
So, in a multiple-unit system, when the compressor of an outdoor unit does not operate due to a lower thermal load, its heat exchanger is kept active to maximize heat exchange surface and efficiency.
Phe (plate heat exchanger) subcooling
Plate Heat Exchanger as a secondary intercooler boosts up refrigerant subcooling and improves 10% energy efficiency.
EMS (Energy Management System)
- Floating refrigerant temperature for balancing comfort and efficiency
The evaporating temperature (in cooling) and condensing temperature (in heating) are automatically adjusted according to both indoor and outdoor temperature to maximize the comfort and energy efficiency, increasing the seasonal efficiency by 30%
- Capacity output limitation for shortage of electricity
With the integration of EMS, for projects with limited electricity supply, MV6R can be set to output 40-100% capacity.
Evi (Enhanced Vapor Injection) compressor
Thanks to the vapor injection DC inverter compressor, the MV6R series can run heating mode stably down to -25°C, furthermore strongly increasing the heating capacity especially at low ambient temperature. Compressor is designed to run at 7% modulation minimum, highly improving system efficiency at part load operation.

Wide Application range
Wide capacity range
VRF MV6R series capacity is up to 18HP with a single unit and up to a maximum of 54HP for a single system with a combination of 3 modules, covering all possible applications and building dimensions.
Wide operation range
VRF MV6R can operate in a wide ambient temperature range.
It can operate stably from -15°C up to 52°C in cooling mode and from -25°C to 19°C in
heating mode.
Simultaneous heating and cooling operation is guaranteed from -15°C to 27°C in main
cooling and from -15°C to 19°C in main heating.
Enhanced Comfort
Night silent mode
The night silent mode feature includes various scheduling options that can be used to reduce noise levels when low noise operation is required: only during night hours or continuously, and with different noise reductions levels limiting only maximum fan speed or compressor speed also.
Enhanced heating capacity
Thanks to the vapour injection DC Inverter compressor, heating capacity can achieve 100% output when the ambient temperature is down to -5°C and 90% output when ambient temperature is down to -15°C.
Continuous heating during defrost
As an alternative to the traditional defrost technology performed reverting the refrigerant cycle, in a multiple-units MV6R system it is possible to keep heating by defrosting alternatively and independently the heat exchangers of different units. Thus, it is possible to supply continuously heating without stopping for defrost operations.
