VRF Systems
The VRF system is a direct expansion air conditioning system that, through a refrigerant fluid, transports thermal or cooling energy from the outdoor unit to the terminal units in the various indoor rooms of the building. Scroll compressors managed by inverter electronics are able to modulate, in a continuous manner, the flow of refrigerant gas, "shifting" the necessary energy according to the thermal loads in the rooms. The system is suitable for the management of summer and winter air conditioning and the production of domestic hot water.
Outdoor units

VRF heat pump systems
The VRF CITY MULTI heat pump systems SMALL Y line, SMALL Y COMPACT line (for small applications) and Y line (for large applications) adopt a two-pipe refrigerant system, which allows the system to transition from cooling to heating and vice versa, ensuring that a high level of comfort is maintained in all zones.

VRF systems with heat recovery
The VRF CITY MULTI line R2 system offers the ultimate in freedom and flexibility in design and use: cooling one zone while heating another. The unique BC Distributor makes simultaneous cooling and heating possible and is the technological heart of the VRF CITY MULTI system R2 line.
