City Multi VRF // BC-Controller


R2 technology

The system's central component is the BC-Controller, which distributes the refrigerant. Up to 50 indoor units can be connected to just one outdoor unit via the BC-Controller with just two pipes. The installation work is much less with two pipes, as fewer soldering joints are required, meaning there are fewer connections in the system and a lower risk of leaks as a result. Up to 950 metres of pipe can be laid with the R2 system and a maximum of 2,000 indoor units controlled centrally. With water-cooled R2 systems in particular, the recovered heat is released into a water network and can be stored if required.
