Fujitsu have announced they are extending the RB Box range to include 8 and 12-ports for 3-Pipe Heat Recovery VRF systems. These will accomany the 1 and 4-port RB boxes that are already available.
As per the existing 4-port RB box, the three pipes from the outdoor unit can be connected to either side of the RB boxes which allows them to be left or right-handed within the ceiling to suit the installtion. This eliminates complicated cross over piping arrangements.
Condensate drains are not required for any of Fujitsu’s RB boxes.
