Refrigerant Branch Units – Fujitsu General America
PINEBROOK, N.J. — Fujitsu General America has introduced two larger Refrigerant Branch Units (RBU) to simplify installations and to expand the heat recovery capability of their VR-II Series Airstage VRF systems.
The new RBUs, which manage simultaneous heating and cooling in heat recovery systems, can serve between eight and 12 zones. Previously, only four zones could be served by a single RBU.
