The Dx-Interface RA (Return air) control type
enables a third party DX-Coil to be connected to a Toshiba Carrier VRF system
(SMMS-e, SHRM-e). This controller enables to handle up to 16 ton of Dx-Coil. The DX-Coil which is controlled by Dx-controller
works as one of VRF indoor units.
Additionally VRF systems require an appropriately sized
Dx-PMV kit
which must be brazed to the DX Coil used in conjunction
with the
Dx-Controller
.
The Dx Interface RA control type also allows the larger Dx-Coil application by two Dx-PMV kit by one Dx-controller in one Dx-
Coil, or Interlaced / Split faced Dx-Coil with multiple Dx-controller and Dx-PMV kit.
