FS-BOX
Flow Selector boxes are required on the Toshiba Carrier VRF heat recovery system available in multiple styles and sizes. Combination of single port and multiport Flow Selector boxes provide ease and greater flexibility during piping layout for a given building.
The Toshiba Carrier VRF Flow Selector Box (FS Box) is a key component in VRF heat recovery systems, enabling simultaneous heating and cooling within the same system. By managing refrigerant flow between indoor units, it supports flexible system design and efficient comfort control across diverse building zones.
Available in single‑port and multi‑port configurations, the FS Box supports adaptable piping arrangements. This flexibility makes it easier to design VRF systems for buildings with long runs, multiple zones, or evolving space requirements.
By directing refrigerant only where heating or cooling is needed, the FS Box helps VRF systems operate more efficiently. This targeted control improves comfort consistency across zones while supporting efficient system operation.
The Flow Selector Box supports VRF heat recovery by managing refrigerant flow to allow simultaneous heating and cooling across multiple building zones.
