The fan-coil TWIN 12 uses dual high-pressure centrifugal fans to ensure superior air distribution. Rather than using one larger duct the twin uses two smaller ducts, one for each ventilator. This allows the installer to use more than one supply grill thus improving the cooling coverage of the fan coil and the effectiveness of the unit. A second and often more important feature is that the twin ventilator's low-profile water coil allows this unit to be installed in an area with little head room. Plug and Play electronic connections make installation easy.
